I'm I insane for thinking that a 1990 Accord in one of the shittiest colours imaginable (light brown) with only 33k miles on it is pretty cool? I mean it's pretty much only due to the fact that it's like new.
It's so obviously driven by a pensioner, and therefore still in pretty much mint condition.

VVVVV: I won't lie, I did actually entertain the thought of buying it. I think the novelty of being a pensioner would wear off too quickly though.

How likely is it that the AC will need refilling due to that the car has been standing for ~4 years without use, and not because there is an actual leak?

Owner lists the classic "AC needs refill" in the ad, which usually means it's shitted itself, but in this case the car has been unused for 4 years. Also, isn't it odd that a CV-joint breaks, gets replaced and then breaks within a year?

refrigerant doesn't leak particularly faster when sitting, but it does naturally seep out over long periods of time. How old is the car?

Memento posted:

First question: reasonably likely. If the AC isn't used regularly, the oil doesn't get pushed around the system and the seals can perish and let the magic gas out.

Second question could easily be down to driver behaviour. I drove a Mazda 323 Turbo (very similar to this but with a TD04 turbo running 16psi) for eight years without losing a single CV joint. I sold it to a friend's little brother and I replaced three for him in the space of a year. Anyone who drives a powerful front wheel drive car and likes to floor it with the steering wheel cranked to full lock will break them on the regular.

I see. Which means it's probably been driven hard.

After doing some quick rough calculations: It's $1500, and with transport + fix it up + sort the import I'd probably spend another $1500, which would make it 2/3 of the price of most with the same year / miles. It's too big a risk, since on the pictures it has lovely rims and lovely sound system stuff. No leather neither, so it's not worth the risk. Don't really want to deal with a car that hasn't been driven for ~4 years neither, that is too far away to go check out.

Thanks for the info though, I'll keep those things in mind for the next time.

What tires should I get for my rear wheel drive car for winter. It's only bellow 40 for about three months out of the year but it rains more than just about anywhere else in the world. Never had anything but 4x4s for the winter with all terrains or better.

I'd get proper winter tires, put them on when the average temperature is ~41 and be comfortable and safe. Especially if it snows or goes below freezing (early mornings?). But even if it doesn't, winter tires are going to handle everything much better at below 40 than summer tires or all season tires (which suck) do.

I've sort of ignored cars for a long time and I barely know how they work let alone how to do any sort of basic repairs. Is there a good online resource or book that explains how cars work and goes into detail about mechanical issues and upkeep?

When I was first getting into bicycles a few years ago I stumbled upon Sheldon Brown's site, which is a fantastic resource for everything from technical details to bicycle manufacturer history. Reading that site increased my knowledge of bicycles enough that I was able to assemble my own bike from scratch and do all sorts of repairs. Is there anything similar for cars? (I recognize cars are quite a bit more complex than bicycles. I'm not expecting to be able to assemble my own car after reading a book/website)

Hah, I too used Sheldon Brown to learn more about bicycle stuff.
Some of the YouTube channels I watch are ChrisFix (quick How-To-Videos that show a brake change in 10 minutes or less), EricTheCarGuy (more of a slower film through the process of him fixing something on a car). I like the ChrisFix style for specific jobs, but EricTheCarGUy style for general understanding, and getting comfortable with cars. There are tons of videos on the tube. If you get into detailing, AMMONYC is my favourite. He revived my OCD.

Also, car make / model specific forums are always good. Well they can be, if there aren't total shitlords. It kind of depends on the car make. I know Alfa Forums are usually extremely friendly and helpful, while the Vauxhall forums (I know because I read up on the M32 gearbox) have "gurus" that can be dicks to people asking about jobs deemed "too hard for plebs to do" by said gurus.

So for some reason I've been reading about rust on cars instead of doing my drat thesis. I noticed that pretty much every video about rust repair on YouTube has > 25% dislikes. From what I gather it's (when it's not clearly a hack job) because of not removing the panel that rusted, regardless of if it's cleaned or not.
But at the same time I've seen guides on websites where they wire brush it / scrape it, chemically treat it, wire brush it / scrape it, chemically treat it, et.c. until all rust (including the rust in the pitting) is gone, then they treat it again to protect corrosion while they work on it. After that they epoxy it then paint. This was an area the size of maybe 4x4cm on a trunk.
Wouldn't this work fine?

Also, what's a good way to keep rust away from the underside of a car? Besides cleaning it during the winter, I've heard different stories. In one camp they are all for the undercoating and treating it, while in the other they say that all this does it make it look nice, while rust grows inside the coating and it's harder to spot. Then there is stuff like Dinitrol which seem to work.

Some vehicles are easier to undercoat than others.

I'm no expert though and this is just from my own personal experience

I used this spray stuff called Fluid Film on the underside my 2013 Prius C. - it's a very oily lanolin-based stuff that protects the metal from rusting. I sprayed it on the underside of the car - every chassis and suspension bolt head. Sprayed the tie-rod threads too to make them easier to adjust. So far it has worked VERY well. Even after two years - the coating is still there.

Thanks for the info guys. I'll check out Fluid Film.
I finally found an Alfa 156, that the owner put through a Dinitrol rust protection thing when he bought it 5 years ago. I don't know if that a local thing or exists in the US / rest of Europe, but basically they keep the car for a couple of days, inspect it, spray anti corrosion poo poo inside all the cavities and protect the underside.
The owner hasn't noticed any rust so far. If I buy it, I'd like to keep it as free of rust as possible. But I'm not spending 1/5-1/3 of the cars value on rust protection if I can help it, which is why I'm researching rust protection. Doesn't help that I live in a country that sees snowy winters, and salted roads.

Now I just gotta go see the car and fail miserably at haggling and pay too much.

So I drove 3½ hours to see an Alfa 156 today and on outside inspection it was in very good condition (found no rust at all, and I was pretty thorough) except for some minor cosmetic stuff, even less stone chips than on our 2014 car. So far so good. But when we went for a test drive my first reaction was "Woah this engine / exhaust is loud as hell", but then when I accelerated up to motorway speeds (worst when accelration) there was a very loud drone. I couldn't hear what my dad sitting in the back seat was saying to me, and to be honest, after I few minutes I felt drained. My girlfriend noticed it too and was annoyed by it.
So I tried to pin point what the sound could be caused by and put the clutch in at different speeds, which did nothing to change the sound. It was 100% dependent on the speed we were going, with the exception that it got worse when accelerating. The owner said that he never noticed it (which is pretty insane, but could be because it's slowy been getting worse) and that it's been the same sound since he got it 5 years ago. So we swapped places and I sat in the front passanger seat and it was just as clear but I now noticed pretty heavy vibrations from the the floor panel where I had the feet (pretty far up forward), which got much worse (as with the sound) when he accelerated hard. It was so loud that I couldn't hear the engine rev, and that's even with a "sportier" exhaust fitted.

We had some theories and I guessed that it must be wheel bearing, drive shafts or gearbox/flywheel since it wasn't dependent on engine revs, but vehicle speed. No change in sound when turning, and was only silent at very low speeds.

I walked away because I reasoned that I don't want to pay for an already overpriced car where I then have to fix a sound like that. Also I don't think I could have drived 3½ back with that sound without stopping to take breaks.

Anyone have any ideas? Not going to buy it but it'll be good to have an idea what the hell it could be if I even encounter it again.

Even with the sound coming from the middle front, and there was no change in sound when turning the car? If it's "only" bearing I probably could have changed them pretty cheap, but like I said, I don't think I could have driven for 3½H with that sound. Oh and the clutch had very little travel. Might just be how those cars are, but 10-15cm travel feels a bit little.

I chose to go with gut feeling, and walked away. Maybe it was a mistake if it's "only" a bearing. Oh well. Still amazed that the owner didn't notice it.

Any chance it had a lightweight/aluminum flywheel? I have a 12lb aluminum flywheel in my Focus and it makes all kinds of excess noise that would be a massive cause for concern if I heard it without knowing about the flywheel.I get a grinding/scraping noise when I'm rolling in gear off-throttle or while engine braking, and the car almost sounds like a diesel at idle from a rattling noise the TOB makes that is normally absorbed by the stock 30lb flywheel.

I should add that these noises are totally normal with a lightweight flywheel in my car, numerous other people with the same modification have reported the same and I've put many tens of thousands of miles on it without any mechanical issues.

No clatter that I could hear. None of the grinding or scraping noise. At first I was confused as hell because I heard what I first thought was engine sound, but then I looked at the rev counter and I was on ~2k, and the sound was pretty constant. So I realized that I couldn't actually hear the engine at all when driving, except when accelerating hard. Barely then to be honest. The owner had no idea, and he bought it from a dealer. It really was unberable.

For reference, my old '98 shitbox Carisma I had a couple of years ago wasn't even close to being this loud. The 156 is 6 years newer and a "premium" car by comparison so it really isn't normal. If it's a mod that makes it sound like that I'm not interested anyway. Just sucks to drive for 7 hours to have a problem like that show up, and the owner not noticing. Really weird.

Edit: Ok after listening on youtube I'm 90% sure it's the wheel bearing(s). Mystery solved I guess. Now I know. But that also means that the owner has been driving around with bad wheel bearing for years. :psyduck:

This is a really dumb question, but how the hell does one stop smoothly in an automatic? I never drive autos, and when I drive normally in my manual car I always let up the brake just before the car fully stops to eliminate that jolt that otherwise arises when holding the brake in while fully stopping. I've never been able to do it in an automatic, and it's even worse when the car has a stop/start function.
Is it just something that will come with time, or is it pretty much impossible to do in an automatic? It might seem petty, but I don't think I could live with having that drat jolt every time I fully stop now that I've spent almost 10 years not doing it.

Another thing I can't stand is the "lag" between pressing the gas and the gearbox deciding what gear to be in / downshifting where nothing seems to happen. Obviously this is something that varies from car to car, but I had a rental Volvo V40 that was utterly useless. The Hyundai I40 I test drove yesterday was much better, but still felt very uncivilized compared to driving with a manual. I don't know what to try that isn't a super expensive car, that still has a good enough automatic.

Also I never get the feeling of driving / having proper control of the car in an auto, but that's probably just a habit thing.

The reason I'm whining is that the girlfriend likes automatics, and more and more new cars are automatics so I kinda want to know how much it's me and how much it's the technology. I don't really want to spend a ton of money on something that I won't enjoy in the end.

Modulate your braking pressure. Learn to anticipate that jolt, and ease up on the brakes just before it happens to mitigate the jolty feeling.

So in other words, it's not possible avoid completely. I did get close to avoiding it, but then the brake pressure wasn't enough to keep the car from wanting to drive again.

Really stupid question incoming. I recently got a new car. In the past I have had cheap, beat-up cars that just served to get me from A to B. Now that I have a nicer, new car, I'd like to ensure that I take good care of it. I'm well aware of all the preventative care/maintenance I need to do for it, but I need help on the exterior.

My car has to be stored outside, with no cover from the elements. I live in the bay area, where the temps are ~30-50 at night and 60-90 during the day. It is incredibly windy where I live and rain is sporadic (though infrequent lately). It usually gets a lot of sun during the day. However, there is a fair amount of humidity and the car is often wet with dew every morning. I've been washing it using gas station car washes every few weeks, but it feels pricey for what I'm getting (not much). What are some recommendations for cleaning and protecting the car? I've tried searching online, but there are so many brands and products that it left my head spinning (do I need to use clay or wax or polish or some combo of all three). I found a self service wash area nearby that I can use to wash (can't do it in driveway due to drought restrictions). But I need a little help with the other stuff. I have a really old (10+ years) can of liquid glass that I remember a relative swearing by. But I'm open to other suggestions. Ideally, I'd like something that isn't super expensive, easy to use, and won't require a lot of reapplications (I have a 2 week-old that is taking up a lot of my time and energy). My biggest focus is something that can repel the moisture and prevent a lot of dirt/pollen buildup and sun exposure from affecting the exterior. Any tips ro recommendations?

Whatever you do, don't use any brushes, water blades or rough towels on the car. You could get the car treated ("sealed") professionally, which is supposed to last a long time and make it easier to wash. I don't know what options are available in the US. After that you could do a quick pressure wash every now and then (before it gets too horrid) and be happy with that.

If you want to do it by hand, properly I'd get some nice stuff from theragcompany.com (I think they have starter kits), a couple of buckets and some products like Meguiar's. Watch some videos on youtube.

How silly is it to buy an "almost finished restoring it" 65' Corvair Coupé with "a lot of spares" assuming that it's complete? In the US, not very. But I'm in Europe and have to rely on getting parts from the US which means 100% more expensive after shipping and customs.

Some old dude selling it unfinished for $2700 due to illness. I didn't know anything about the Corvair before, but it's a cool blend of European and American styles.

In general, unfinished projects sell for way less than what's been put into them so far, but you're at the mercy of what's been done so far, and to what standard. They may have dealt with a lot of stuff already, or they may have made things worse and added more jobs for you to do.

You need to go take a good look at it and assess whether you think it's worth it to you.

Speaking of condensation: I recently (as it's getting colder) noticed the windows fogging up, then I noticed that the passenger side floors were soaking wet. As the sides and roof lining are bone dry, the prime suspect is a clogged A/C drain and that it's been going on for quite a while.
The next suspect is that water somehow is getting in from under the car, but assuming that there aren't any rust holes etc, is that even possible? Most of the bottom of the car is covered in plastic undertrays, but I kind of recently broke a couple of screwets, and it's not as "tight" as before.

I haven't had the time to get under the car and have a look. Been doing my best to try to dry it out so far.

But I need to take off the wipers to access the scuttle bay, not something I can really do here since I got street parking.
The only other thing I've done is spray some (low viscosity) Dinitrol rust proofing into the rocker panels / beams. Nothing that should in any way clog up potential drain holes or anything.
Have to buy some time right now, might be able to get away and pull out the passenger side interior and dry it out / go leak hunting. :v:

How should I go about fixing this scratch? It looks like maybe some parts of it are down to the metal, and possibly have a little rust on there. It could also be that the scratch was caused by a wall and has brick dust in there.

Worst case scenario, am I gonna need to shell out a couple hundred pounds for a pro to fix this, or is it something I can do at home given time and internet expertise?

I've seen people online posting about rotary buffers and wet sanding and it seems like a lot of money invested, and I have no idea how much of that is necessary.

If it isn't an expensive car and you have access to a garage I'd try to paint it myself. Might not be perfect, but with 2 component paints and good prep work you can get good results. Especially since it probably won't be a couple hundred pounds to fix unless you get a "really good price".

I expected it to be worn tie rod ends or a blown out steering box or worn intermediate shaft ujoints, but it ended up being the nut on the TRE at his pitman arm was 3 turns looser than it should have been and the taper stud was flapping around in the hole :aaa:

He'd been over it a few times looking by hand and trying to identify the feeling, but what it took was him wiggling the wheel a few inches back and forth while I looked at all the moving parts and found the one that was moving where it shouldn't be.

Thanks, I'll do that tomorrow. In the meantime I did some more research and this model (and the ones that share the chassis) apparently eats strut mounts for breakfast lunch and dinner, so it's very likely. No play in the steering. I recently MOT:d it and specifically asked if there was anything about the suspension that seemed worn, but there was nothing. It's been the last couple of weeks or so (also with freezing and thawing temperatures) that the sound (and vibration to the floor) has been present.

The suspension mounts are located in the scuttle tray, and not inside the engine bay like on other cars, so they get exposed to a lot of rain.

I read that catalytic converters don't mix well with carbs due to the small band of air fuel ratio needed. Or that's just people exaggerating?
I'll look into the later year motors (didn't think about that) and fuel injection.

Does it still run on leaded petrol?

If so, getting hardened valve seats and running it on unleaded will save a lot of brain damage.
Would prefer to not make people around me even more braindead.

I don't actually have a car that needs it, but will probably have an older car in the near-ish future. I don't really care about the CO2 emissions, because compared to a new car it's already better off from being old. I'm more concerned with the local pollutants if I'm going to use it a lot. I probably won't mind spending a bit just to clean it up. Especially since I'm likely to drive in the city. I'll probably get a car from the mid 80's, so it'll probably have some emission reducing stuff on it from factory.

May have some? Everything from that time is going to have cats and a sealed fuel system at a minimum. In good repair many are likely to be drat near the same as an average car from the 90s/early 2000s.

Ah yes of course. I think I was a bit too tired when I wrote that. No reason to "feel bad" for driving an older car then really.

Ok, then I'm back to my earliest possible solution. Sticking a hockey puck between the frame mount and the stand, just like this:



Is this safe enough?

If you want to be even safer, cut out a bit of the puck so that it fits the jackstand "head" snugly. I actually bought some hockey pucks that I'm going to make into pinch weld adaptors.

As far as Youtube... for any reasonably common car, you can put in <car> <job to complete> and find at least a few reasonably detailed walkthroughs on it. I like both ChrisFix and EricTheCarGuy myself.

Just as small note: If you watch ChrisFix and decide "Hey he's pretty good at fixing cars, lets watch his "detailing" videos". Be mindful that that's one area that he's lacking pretty severely in.

I'm back with more manual transmission questions (is this the right thread for this? seems like most people need help fixing their cars, not driving them) I did my first long drive in a MT car this weekend and want to clarify a few things about driving stick on the highway. My wife (the owner of said manual car) has her own way of doing things but it's often at odds with what I've seen online, so I'd like to understand not just the what/how but also the why. For reference, the car is just a 2008 civic 5MT.

1. Merging on to the highway: a couple videos I watched online showed people merging in 2nd or 3rd and then shifting up once in traffic. One guy stayed in 2nd and seemed to push his car up almost to redline. My wife likes to just gear up sequentially and be in 5th before merging in. She likes to shift to 5th gear at about 90km/h. Seems to me it would make the most sense to take 4th gear up to 100km/h (putting me at maybe 3500rpm) and then shift to 5th once I'm on the highway. How do you do it?

2. Passing: everyone online seems to say to downshift if you want to pass someone on the highway, with some people even saying they get down into 3rd. My wife just stays in 5th gear. I find the car basically has no pull in 5th when I'm already going 110km/h or so, but she says putting it in 4th at that speed would be bad for the engine. Is this just econobox reality or can I drop it into 4th and get some extra acceleration at that speed? Is it bad for the lifespan of the car to do this?

Also, this is getting more into "how do cars go" territory but why does downshifting let you accelerate faster even though I just as often hear people talking about downshifting in order to engine brake?

Huge amount of variables, but rule of thumb is to always be in a gear that allows you to react quickly when in situations that require it. Then when it's chill, highest gear possible for best MPG. When it comes to passing it's down to the car / situation. If I pass on a highway I usually don't have to shift down because the car has pull and it doesn't lug the engine. If I pass on a country road I usually downshift to get past as quickly as possible. Lugging the engine is worse than revving it. People such a weird aversion to revving engines.
Why you shouldn't do what you wife is doing:

Also lol paul walker. You think John Q Public washes their car more than once every couple months? If bird poop did damage to modern cars you'd see millions with shoddy paint.

...but that's also why John Q Public drives around in a filthy car with lovely paint that when they actually decide to wash it they just make it worse by using a local swirl-o-matic wash or decide that they'll manually induce the swirls by using sponges they drop on the ground / the local wash bay brush.

If I can feel grooves on rear disc brakes, how bad is it?

lovely picture but can't take the rims off right now. At least the pads seem to have a lot of material left.

Eh, that's pretty normal for an old rotor. That looks like a small (1-2mm lip) where the rotors are worn. As long as you're not nearing the rotor's minimum thickness, the pads are wearing evenly, and the rotor wear is consistent across both sides I would file this under 'replace rotors when pads get low.'

Cool, thanks! I figured that the MOT-equivalent would have said something 6 months ago if it was in horrible condition. I don't drive very much, so I doubt there's much wear since then.
