If you live in a big enough city you can usually find someone around town who will clean out the carbon build up for a few hundred dollars.

That reminds me I need to do it in my Genesis, a little over 50k and I'm sure it's easier to get rid of before it gets bad. That being said, I'll take it any day over port fuel injection. They added about 40hp by bumping the compression ratio of the motor and increased fuel economy while doing that. Worth the occasional extra maintenance to me.

Does no-one sell carburettor cleaner where you live? Dump a pile of that in the intake, leave it overnight, take the plugs out the next morning and give it a crank (or turn it over by hand, or if you're feeling brave/foolish or crank it with the plug leads off) and put the plugs back in. Your engine oil may be somewhat secondhand if the stuff bleeds down your rings.

They even make a version for cleaning valves by injecting it into the intake with a straw under the throttle body.

The normal cleaning method is walnut blasting so I'm sure seafoam will work perfectly.

I doubt most people will notice it until it starts affecting performance at the 0-30% engine power range, given that most drivers seem to think they will break the car if they do more than breathe on the throttle/brake, corner at over 15mph, or turn the steering wheel past one turn in either direction. At that point the ports are probably mostly full of carbon buildup.

At least that's not as bad as an issue with the engine of I think the M5. There are ports that run through the entire engine for some sort of emissions thing that eventually fill up with carbon and get clogged. This does't really affect performance but it does pop up a code in the ECU. The only way to clear the code is to take the engine apart and run a pipe cleaner through all the ports to clear them.

That sounds remarkably like the emissions system on an Audi 1.8t engine, except those also have a multitude of bespoke molded rubber elbows and tees and poo poo that have turned into a strange amalgam of tar and dried up rubber that shatters the second you look at it funny except it also leaves thick greasy tarry sludge on your hands, oh and they're all held on with oetiker clamps. It's loving bullshit and a friend of mine tuned his just to delete all the emissions codes for that system so he could rip it off and put blockoff plates on instead of spending 3 figures on bullshit at the dealer to reassemble it after painstakingly de-sludging/de-carboning the whole thing.

IIRC this was the E39 M5 and only was an issue if you didn't regularly flog the car.

Lightbulb Out posted:IIRC this was the E39 M5 and only was an issue if you didn't regularly flog the car. Yeah my brother has an E39 M5 and it has that problem. It's an issue with the secondary air injection system specifically. He daily drives it on a highway to get to work and definitely isn't the most conservative driver but it cropped up anyway. At this point those cars are getting up there in terms of mileage so it almost seems like an inevitability that this issue will come up unless you take it to the track for a full-on Italian tuneup every few months or pull the heads and get them walnut blasted. Like someone else mentioned it doesn't really seem to affect performance and just turns a light on so he ignores it. Also while we're on the topic of carbon buildup..      2005 Corolla (1ZZ-FE engine) that I did the intake manifold gasket on a while back. The factory manifold gasket was poorly designed piece of trash that could fail as early as 30k miles and this one still had it at ~130k with the associated massive vacuum leak. The entire intake tract has a nice thick layer of buildup but the valves were perfectly clean. I never did find out where all that oil came from. The dipstick level never moves so it's almost as if someone dumped half a bottle of oil on one corner of the engine and left it there.

The old fashioned way to clean carbon off intake valves was to get it really good and hot ( 10 minutes of highway speed) hold the throttle plate slightly open and let it ingest a pencil stream of water which will flake the poo poo off the valves. Probably not viable on anything with a cat but hey

One of the big culprits is PCV valves that never get changed and block up, which I assume forces oil vapors backwards down the fresh air hose for the PCV system.

Yup; I've read about all the issues like stuck piston rings and other stuff but like I said the oil dipstick level never seems to move. I replaced the PCV valve too at one point and the old one tested good so..  The oil dipstick probably isn't a very accurate measurment now that I think about it. I should find some time to give the engine block a good clean and see if anything is leaking. I haven't taken the intake manifold off again since doing that gasket two years ago because

I have to admit something. I have no idea if my engine has PCV, and if it does, no idea where the PCV valve is. There's a breather hose from the valve cover to the intake, but I've never been able to find a part number for a PCV valve. Rockauto does list a "PCV Breather Hose" that looks like the hose I mentioned. Almost 155k and it loses about a quart and a half between ~9-10k synthetic oil changes, so if it does have a PCV valve, I guess it's working the way it should? I'd assume it's built into the valve cover if it has one. I've never even had the valve cover off, so I have no idea what it looks like inside.  e: I guess I'm the horrible mechanical failure here, but if it ain't broke... drat thing doesn't even leak. randomidiot fucked around with this message at 07:28 on Oct 12, 2016 |

I don't have any photos as evidence but I swear a majority of the Cayennes and X5's I've seen is recent months have had the back tires bald for at least a 1/3rd of their depth. Always on the outside of the tire and some worse than others but generally the back tires are knackered. Is it a case of not giving a poo poo or do the tires really wear that poorly just on the outside 1/3rd? I think the winner of the award though was the X5 with all four tires bald on the outside edges.

X5's and Cayennes now hit the mark of Cheap enough for the poors to buy a 10 year old one. My work parking lot have been recently filling with these and I know why: (It's not like I work at a place where the majority makes bank. I"m probably in teh top 10% of earners in the building and I don't earn that much. ). People buy them because "HEY I can get a Cayenne/x5 for less than a 2013 civic, time to live the baller style life I wanted 10 years ago when they were 70k!" Drive them on the tires that came form the used dealer which were probably passable at the time, and don't align it because they can only barely afford the car. Shop says you need tires sometimes soon.. that'll be $1,200 Continues to drive on bald poo poo tires with no alignment until tax money comes.

I saw a guy absolutely lose it the other day at a tire shop because he was told that after blowing out one tire on his BMW X3 he now had to replace all four rather than chew up the centre diff. I'm guessing a full set of tires for that X3 was probably about the same as what he would have paid for an entire used Corolla.

I had to replace all four on my Corolla the other day. The mechanic pointed out a couple of tyres sitting on the other side of the shop, initially I thought they were racing slicks given the size of them. Nope just off the back of an X5-M and bald as gently caress. Apparently the woman only replaced them due to a massive nail through one, the fronts were just as bad but NOPE

I'm not sure if it's related but X5s always look like they have a lot of negative rear camber. Not sure if it's just the wide-rear end tyres accentuating it or if there's some suspension fuckery going on to try and save the outer edge of the tyre.

Many new cars come with the rear set up like that. Basically they assume the bushing which helps keep that alignment true will wear out. Thus no longer having so much negative camber.

We usually take camber out of the rear when setting up most modern cars for track to get a smidge of rotation.
