That fuel pump/filter arrangement looks familiar, but I can't decide if it was from my '88 Volvo 240 or from my '79 280ZX. Or am I wrong on both counts?

I wonder how long you can go without an oil change with an otherwise well maintained car running on synthetic under light driving?

On some modern cars, 15-20k is really not a stretch. I do 7500 miles in my turbocharged direct-injected four cylinder that's known to be harsh on its oils. With a larger sump and no turbo, the oil life could be considerably lengthened.

So, everyone fucks up, but man gotta hate on Ford because going 80+ over 18" bumps caused a repair bill of LESS THAN $1000. Jesus dude get over it.

I will say I wonder how many times you could get away with causing the same damage before you utterly scrap the frame - but then again I would hope that anyone who doesn't decide to go slower after the first time they do it would reinforce the thing instead.

Ignition systems are one of the big reasons modern cars behave so much nicer than old ones. Points systems required frequent replacement (and extremely frequent adjustment), standard coils couldn't put out all that hot of a spark, copper plugs don't last all that long, and long plug wires make those sparks even weaker. God help you if your advance mechanism failed for any reason (vacuum, mechanical, whatever).

By comparison, most modern ignition systems really can go the better part of 100k miles without even a second glance, and even at 100k miles, they'll outperform a fresh points setup.

YOU SHUT YOUR WHORE MOUTH :argh:

(and get off my lawn)

I put a $100 aftermarket HEI distributor (that $100 included everything from the drive gear through the cap and coil) in my truck to replace the old points setup, ran new 8mm plug wires, fresh plugs, and a non-resistor wire to feed the thing true 12V. Picked up at least two tenths in the quarter mile and 2MPG driving around town (went from averaging 10MPG to averaging 12MPG)

If/when I ever pick up another vehicle from that era again, step one is making sure the brakes work 100%, step two is making sure it runs okay as it is, step three is ditching the points in whatever manner is most economical.

How the hell is it that this is one of the most common fix 'er uppers? Are the battery brackets wear items on some cars or something?

I don't know why, but all of my cheap old cars - Nissan 280ZX, Volvo 240 and my Ranger - came to me with the original hold downs long since MIA. I tried to put an aftermarket holddown on the Ranger but it doesn't work so well, so it's pretty much going with Option 3. The Volvo also went with Option 3 and it was only a problem once, when I took a bump too hard and it pulled the positive wire out of the clamp, causing the whole thing to shut off.

What year Ranger? I think on my '98 it's a floating disc with a separate hub/bearing assembly, but on my GMC (and even on the '97 Suburban I learned to drive in) they did use the rotor as part of the hub. It makes it a pain in the rear end to get rotors turned or to replace them since you have to gently caress with the wheel bearing at the same time.

On one hand, there is zero excuse for Ford to let that car out the door with a driveshaft that's imbalanced at all. It may be "just a V6" but it is a 300hp car, and five years ago if someone had done that in a GT nobody would bat an eye / everyone would be screaming about Ford's poo poo quality.

On the other hand, there's equally zero excuse for why he kept his foot in it with an awful racket like that. Presumably he had to feel it too.

Way back in the early days of the fourth-gen F-body, a number of six-speed cars got out with imbalanced driveshafts, but you had to get it up over 100 to notice. GM still put out a TSB for it and gave anyone who complained the aluminum 1LE driveshaft.

IOwnCalculus

There's nothing wrong with the design of the car as a whole, the same car with a V8 will do those speeds without batting an eye, and I doubt the V8 has a significantly different design on its driveshaft - just bigger / better-balanced parts, my guess.

Cowwan posted:

I'm not saying there is something wrong with car as much as there is probably a reason for the limiter, even if it is just to sell v8's.

Usually it's just there for the tires. To go back to the fourthgen example, if you didn't tick the "Z-rated tire" option on an LT1 Z28, you got a speed limiter. If you did, the limiter disappeared.

Also, apparently the GT does have a significantly different driveshaft design - apparently it gets a two-piece. That seems...dumb. This isn't the '80s where the base Mustang is a Pinto-engined slug, or the '90s-'00s where the V6 is only the providence of high school girls.

The upper ball joints on my mom's Ranger were worse. The right side had a rusted tear in the top metal cap, there was no grease inside, there was a solid 1/2 cm play in all directions.

I replaced brake discs, bearings, pads, UCAs, lower ball joints, put it back together, one day later it blew the hardline that fed the back brakes. Fixed that, then the filler neck rusted through. Replaced that, still leaks a bit, need to drop the tank to replace the hose. The tank is plastic, so it CAN'T rust. Noticed while I was under the truck for the filler neck that the bedliner is now the main structural component of the bed. gently caress that truck.

Blagh. I know for a fact most of the front end of my Ranger is grease-free, but it still seems to go down the road well enough. Can't bring myself to spend the ~$400 or so in parts to do a full rebuild.

Ding. Insurance paid for all of it already based on its actual value as an engine / cargo / etc, so what's left can only be scrapped. There was another wreck which I forget the name of that had scores of mid-'00s Mazdas on board, including a bunch of Mazda3s and I believe early NCs. Despite the fact that most of them had no actual water damage and had just essentially been parked on a hill, Mazda / their insurance company didn't want even any of the parts from those cars on the road. Even only for track usage. They were all crushed and recycled, along with every other ounce of metal on the ship.

I would assume it its to isolate and cushion failures of the various parts., you don't want a seized alternator damaging your water pump, and you really don't want the entire thing stopping abruptly when 1 part fails.

Well, it has been done to a limited extent before - the GenII small-block Chevy (LT1/LT4) had a water pump driven off of the cam. Never heard of a catastrophic failure on the drive side of it, but the fuckers do leak like a sieve...right onto the water-sensitive Optispark!

That said, a lot of cars now have electric power steering; it's easier to package, and reduces parasitic losses considerably since now you're only loading the alternator when you're actually turning, instead of loading the belt drive all the time. I think many hybrids run the A/C compressor on electricity as well so that you still get cooling with the engine off. The water pump could be electrified either with more voltage, or maybe direct driven like that LT1, and then your only belt is the alternator.

so what makes a lot of noise? those gal'darn timing gears thats what.. so instead of making them out of a metal, westinghouse devised a fibrous material that held together extremely well and virtually eliminated noise and cut down on wear of the crank gear. They stuck around for many years but by the late 50s engines were making much greater power and the non metal timing gears were replaced with metal.

Nah, they never went away completely during that time. My 70's original 350 had one and sometime around 20 odd years ago it just separated from the camshaft. Did similar amounts of damage from what I was told, plus a timing cover from the chain running slack.

No poo poo, bodywork / panels / painting in the US is not cheap. The fender-bender (literally) in my Miata ran about $2k to repair and that couldn't have amounted to much more than a new fender, headlight, some plastic clips, and a tie rod or something similar. Nothing needed to be welded and only the fender needed to be painted.

In theory you can fix that because it wasn't as horrible as you think it was. Those pieces generally are replaceable.

You'd need a new armature and brushes, and depending on the cost of those parts / condition on the case and bearings of the motor, it may just be cheaper to replace the entire motor.

My first question is how is he going to handle throttle inputs to two vastly different engines?

I'd just run them both as cables, and perhaps put a lever on one of them so that the same amount of pedal travel gets you to 100% throttle on each engine.

The wildly varying power levels shouldn't be "that" different than a car with a 30/60 rearward bias on AWD.

So? Why would it matter if the front engine is doing 3000RPM in third gear and the rear is doing 4000RPM in second gear, if that's what matches up to the same forward speed? It's not like he's actually hooking these things up with a transfer case.
