some texas redneck posted:That's what I was thinking. The calipers are likely fine, but the lines are already rusting, and the master cylinder and ABS pump aren't designed for that kind of heat. No telling what kind of damage was done to the electrical system, particularly with that loom that runs next to one of the lines. Then id put it on the owner.. Tell them that the system was shot and that it caused it. Honestly I'm surprised that the abs system had that kind of power flowing through it.

abs pressure pumps and solenoids draw huge amounts of current due to the required force and speed required for actuation. some specs I've seen seem to suggest surge currents of 60-80A. basically, inductive loads are a bitch.

I guess that's not too surprising since the ABS solenoids and motor(s) probably need a fair amount of juice. OTOH never doubt the ability of a short to pump ridiculous amounts of current through anything. I've had dealings with very low voltage things (we're talking a couple of millivolts at best) that were shorted and left the chassis of the device too hot to touch.

14 INCH DICK TURBO posted:Mechanical failure in progress at the shop. Somehow someone grounded the battery to short on the brake hardline and the master cylinder is boiling over and the lines are glowing red. On standby with the extinguishers. this happened to the clutch of my friends integra. he wondered why teh hell he couldn't get it to start... then the smoke came. I guess that stainless steel braided clutch line wasn't such a great idea after all.

Positive cable to the starter grounded out on the motor mount, the shortest path back to the battery was apparently through my power steering high line, which promptly exploded. It was cool in that "hay this is a novel way to get stranded" sort of way.

On my Integra, the ground bolt was a few inches away from the battery and just clamped near the edge of the hood opening. Well that bolt got a little rusted and wasn't conducting. So I would go out and try to start it, it would light up the dash and then when I turned the key I would hear a CLICK! and then it would go completely dead. Took me 2 weeks and someone standing on the other side of the hood to realize that when I tried to start it, it was jumping a spark all the way from the battery terminal to the bolt, arcing a little piece out of it and draining the battery. So I took that bolt off, cleaned it and the wire, and put it back together, even with all the little divots eaten out of the top of it. Car ran fine.

This is the second time I've seen this magazine referenced recently and each time it's happened what I am reminded of was reading Krass and Bernie as a kid which was drawn by George Trosley and how awkward it was when I transitioned to Hustler a few years later and there was George again, not quite using the same characters but almost. When I was around 12 I used the Let's Draw the 1982 Camaro to draw a poster for the science fair and they attempted to call me out for cheating but when I showed them the magazine and how I did it, I ended up with 1st prize.

Hm, something doesn't look right about this fuel pump. Let's take a clo...    More of a PO failure than anything, but who the gently caress considers JB Weld a good idea for electrical connections near high-pressure fuel?

^ Its not the best of ideas/execution but at least they were on the right track. It isn't electrically conductive after setting so had the wiring been sufficiently covered the connectors would have been insulated.

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?

It's from an '89 240. Fortunately, those globs came off the posts pretty easily, but now I need to figure out what I'm going to do when I wire the pump back in-the connectors Volvo used aren't an off-the-shelf part, and I don't think standard bullet connectors are going to cut it.

are the threads even remotely salvageable? I'd try cleaning them up and soldering on pigtails that could be properly connectorized. Or just replace the whole pump over it.. seems like a waste but I've done it with alternators that I decided were electrical hazards.

There aren't any threads. The stock wiring has push-on connectors, like these: that go into a plastic collar surrounding the stud. Unfortunately, those connectors are long gone from the harness, and there doesn't appear to be any similar replacement on the open market. I'm probably going to have to use solder and heatshrink for the time being.

Assuming you plumb in a good external accessory oil filter? In that case, basically until your car consumes the oil. Otherwise? Not that long. Oil gets contaminated with carbon quite fast.

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.
