You know, there was a picture of a locomotive that threw a piston into a house earlier in this thread. For the longest time I've been trying to figure out how that would happen, and this is the only reason I can think of. I knew about diesels running away but I never really thought about it in this context, thank you.

Do you need me to repost the pictures of the destroyed engine from my first ship? That was a diesel that overspeeded. Messy.

This found it's way into my flower bed. I don't know where it came from. The only two cars that are usually in my driveway are an old suburban and a new Xterra. I guess it's my neighbor's way of saying I need to water my plants?

Seriously, no clue where it came from.




I'm almost positive that's a KA24E water pump - which would be a SOHC 240SX (89-91 I think) or a D21 (Hardbody) 4 cylinder truck.

Looks like it got chucked out a window or something - it's dinged up in ways that just don't happen when you're removing it, unless they took one hell of a big hammer to it. When I changed mine it came off with one decent whack from a mallet, same when I changed one on a friend's 240SX.

I dunno, if that event happened like the other he was describing, if the nut and hub were still attached to the wheel, well, I think the nut did its' job, and was probably put on properly (or terribly hosed up enough to break a hub? I don't think so though.) Of course you can't tell why the gently caress the wheel just pops right off that 911 in the video so whatever, probably some stupid poo poo like improper tightening. But 450ftlbs on one of those nuts? Jesus. Talking about spinning a tire against concrete when the car is fully resting upon the ground, that's crazy.

This was a Volvo B230 with sleeved cylinders, a 2.5L stroker crank, and a half-cemented block. As far as the owner can figure, one of the cylinder sleeves let go at 28PSI and it hydrolocked.

Almost literally what you think it is. It's filling up part of the block with cement to make it resist distortion (sort of like a closed deck block, but on crack).

They also used to call them "hard blocks" or "filled blocks." Old school drag-strip tech.

e: I think they usually pour it into the coolant passages, so a half cemented block would be halfway to the head with cement.

Cakefool posted:

Under extreme stress (read: tons of boost) you get cylinder wall deformation, which usually ends in Bad Things so in some drag car cases they fill the water jackets with filler, making the block more rigid and obviously no longer water cooled.

Drag racing thing. They literally fill half the block's water passages with cement (or a purpose made substance) to strengthen it. The decreased cooling isn't much of a concern when you're only going flat out for a 1/4 mile at a time.

Yes. If the valve seals, piston rings, or turbo start leaking sufficient oil, they will run away. Any diesel can. They'll just eat their own lubricating oil till it runs out and then die a horrible death unless you can find a way to block the intake of air.

But with the locomotives, I'm pretty sure there is a cutoff for the generator to the motors, so even if the engine ran away they'd just cut the feed of power.

on an AC locomotive the em2000 would probably throw the crowbar resistor if the engine runs past 950 rpm. this would lock down the generator and quickly stop the engine.

Plus a lot of those cars are running alcohol fuels, which burn cooler, so there's not as much cooling load.

Why would you ever want only half the water jacket filled with cement? You're blocking all the coolant passages either way, why not fill it up and get more rigidity?

That's not an oil leak. That's the automatic oil change and chassis protection feature.

So you can drive it to the strip, convinced that it's safe since you've still got some coolant flowing but really you're just softening everything up so it blows-out at the drags like the above pics.

DARKEST SKETCH


Lady drops off her 1998 Ford Expedition at my shop for a brake inspection. When asked what kind of problem she's having, she simply says: "It makes noise in the front."

Bringing it in from the parking lot was a borderline suicide attempt. Aside from the extremely low brake pedal and the horrendous metal-on-metal grind of what's left of the front brakes; there was also an obnoxious groaning creak every time the suspension moved or the wheel was turned.

First thing I saw after pulling off the right front wheel:



Turns out that one of the bolts that go through the caliper slide and hold it to the support was missing for so long the other one just finally snapped under the stress. Look close enough and you can see the snapped end still in the support, also what's left of one of the pads themselves:


The brake rotor. Not the worst I've seen, but still pretty bad:



Oh, and about that creaking noise:

VA does inspections. Sometimes I think it's mostly a way for shops to charge $30 for a $.99 light bulb, but though it's a pain in the rear end to have to go waste a few hours some morning sitting in line at a local shop, it really does cut down on the number of total shitheaps plying the streets.

IF I HAVEN'T MENTIONED MY FIVE TON LATELY, CHECK MY AIR INTAKE FOR CHEMICAL WEAPONS


kastein posted:

I've put something like 5k on the one in my other jeep with the head gasket completely blown between cylinders 3 and 4.

All these motors still run perfectly (well, aside from the one with the chunk of missing head gasket... and I drove that one to the airport today) without a single tick or odd sound and perfect oil pressure.

If you want to be able to brutally abuse a vehicle in ways that should never be done, and still not have to replace any major components, buy a jeep with an inline 4 or inline 6.

kastein posted:

I expect the middle of the HG in my 98 XJ to look about the same when I take it out. I think I'm up to 10k miles on it since it dropped two cylinders now. Compression test showed 150, 150, 30, 30, 150, 150 psi readings.

as promised...


hmmm there seems to be a problem


bottom of HG, cylinders 4-1


bottom of HG, cylinders 6-4


top of HG, cylinders 4-1


top of HG, cylinders 6-4


detail: lack of HG cylinders 3-4


cylinders 2-3 were close to burning through too, from the look of it. In fact it probably already started leaking, I felt a noticeable decrease in power from the already horrible lack of power.

Again, this was a running driving vehicle that could be persuaded to maintain 75-80mph on the highway and got 15mpg, or 13 if I drove it like I stole it.

And the best part is that the head and block surfaces look like I can probably just clean it up and slap another gasket in. I was expecting significant erosion and flame polishing since I basically wrote the motor off a year ago and have been trying to kill it since then (4.0s are $100 in my area, I'd rather slap a new one in than do a head gasket in-vehicle...) but never actually succeeded.

Guess it's time to put the new motor in, and maybe throw a gasket in this one and keep it as a spare. Oil pressure was great and there weren't any bad noises aside from the rushing of compression from cylinder to cylinder and the horrible OH GOD PLEASE KILL ME NOW chugging of a 4/6 cylinder motor.

I think the state inspections here in Maine are a good thing. Sure, it pisses me off to make my car safe to pass sometimes, but with all the rust, total heaps would be driving around.
But my car has good joints, brakes, suspension is ok, nothing is very loose, and no rust holes that are too big. And it will pass, it all depends on where you go. He even told me to get the minor fuel leak fixed sometime before next year inspection.

I love it when the only brake light that works is half of the center light but it's covered with a 'GRAND AM' diffuser so only about 1/2 of the light from half of the brake light is actually being shown.
