It was in a bay like that at the emissions station with cement block walls and floor. I went deaf for 10 minutes or so and I'm sure I lost some hearing permanently from that. It was so much louder than any gun I've ever heard.

I'm about 10 pages and 1.5 months late in replying to these, but gently caress it. Original post.Sponge! posted:How in the... Geoj posted:Was this your piston from a few pages back...? GnarlyCharlie4u posted:what in the gently caress? InitialDave posted:"I'm sure we can port it out a bit more, pass that die grinder over here" That last one actually isn't very far from the truth. As far as we can tell, the previous owner ported the heads and made the valve bowls thinner than they should be, then a blown heater hose on the highway caused the engine to overheat, cracking that area of the bowl. Finally, the head got pressure tested which lead to the pencil-sized hole you see in the photo. Billy Tully posted:I bet that guy was pissed when the third head gasket was leaking too. We actually only changed it the once (well, twice if you count the replacement head) before deciding to get the head tested. It was still incredibly aggravating. Moral of the story: Don't buy a racecar some redneck built in his garage and expect it to be fine.

About a year ago, I get a call from a friend of mine saying his truck just went "BOOM" while on the expressway. He said it had been shaking for a while, just "didn't have the time to get it looked at."  I don't think "BOOM" was the only noise made here:   I can only imagine how long it was like this before it let go.    Note the near perfect indentations the drive shaft made in both the muffler and the gas tank.  Amazingly enough, the drive shaft somehow managed to not slip out of the trans. I told him to count his blessings and then play the lottery in hopes he'd win enough money to pay to have a new drive shaft made.

Less of a mechanical failure more of a WTF nature. A picture from a friend of a friend.  From the recent tornadoes a 2x4 driven through the sidewall of a tire.

After the #2 cap broke apart in my hands upon disassembly (  ) and seeing the oil pump carnage, I ended up trashing the block and the crank just to be safe.Now I know the limits of the stock main bolts

Savington posted:Well done. How much power, how many hours? Is that a stock crank? the last tune was 747whp/690lb-ft at 38psi and this happened just as boost came on in 5th gear. We stuck a rod through the side of the block last November and re-used the crank so that probably had something to do with it. 4 events and less than 30 laps on the rebuild. It's a BC, we also have some bent BC I-beam rods and a cracked cylinder wall.

Beast Pussy posted:so your car won't start? Oh, sounds like it jumped timing. It was just about the start of when I was beginning to learn how to at least work on the basics of a car, so it wasn't until a couple of days later when I'm finally going point-to-point (  ) to narrow down why the car does so poorly with any fuel/spark added to turning over, that I took the cap off, and the rotor came with it.Put the bolt back in, with the tiniest hair of lock-tite, and minutes later I'm back to a perfectly working car. Well, and a comedically loud exhaust.

Revolvyerom posted:I had a very similar thing happen to me driving along the waterfront in Seattle on my Z31. Out of sheer bad luck I suppose, the ignition rotor had managed to back out the bolt securing it to the post, and it literally went from one cylinder firing just fine, to the biggest explosion I had yet heard going off right under my rear end under the car. Peeled the muffler open just like that. Sucks to be you. I've had fun things like the distributor shaft disengaging from the distributor drive shaft while driving (2 part keyed thing, VW), and the rotor floating up and getting caught on an electrode. That sort of thing. makes a nice pop doesn't it. Malfunctioning LPG is fun too. Nothing like a failed start letting rip with a bang in the exhaust and intake at the same time. I love having to reassemble the LPG plumbing, drag the punched in filter out of the airbox and re-seat it and close it again when I'm in a hurry. On the subject. Minor mechanical failure with annoying consequences. Anyone know how hot the exhaust on an LPG car gets when it's running lean? You could probably use it to heat a house effectively. A house full of asphyxiated people. Anyway it seems to be enough heat that it can melt the vinyl cover on the front of a caravan over a meter away. It would have been a horrible failure if the caravan's LPG tank were about 1' further right. What happens when a small domestic LPG tank is heated a lot anyway?

It expands, ruptures (generally with some force), and is unpleasant to be around at that moment. That's assuming you keep it away from ignition sources like fire, sparks, or (as they told us in the dept training, but neither I nor nobody I've spoken to had seen the air mix be perfect enough and a car's cables arcing badly enough) a running car. Then it's extremely unpleasant to be around at that moment.

Well poo poo. That would have been unpleasant. I really wish I had access to the DECA "museum". When I was doing training for my truck license we were shown a couple of rooms that had mangled parts laid out everywhere. It was pretty much a student's hall of shame. There were chewed turbos, driveshafts split and bent, wrecked drums bearings and wheels, a few mangled pistons and valves and various other sundry items. We even had to play a game of "guess what that part used to be" for some of them. I guess when teaching people how to drive heavy machinery there will be casualties. Especially people that have trouble understanding that an econobox and a truck with dual range crashbox with half gears are a totally different vehicle.

Having had the unfortunate experience of a SCUBA tank popping its burst disk and providing an exciting demonstration of Newton's second law, I'd say this is optimistic to the point of euphemism. On the plus side they generally have to get pretty warm for anything to go seriously wrong, though a sunny day plus hotter than normal exhaust would be more than I'd like to bet on.

Mythbusters just did something with an LP grill tank - same thing but smaller, right? They put it in a burning building, after about 20 minutes the safety vent popped and essentially created a semi-controlled blowtorch for 10 seconds. The only way they could get an explosion was to rig the pressure release valve so it wouldn't work. Essentially what you get is a big explosion with shrapnel from the broken tank all over the place. To get that they had to set it on a specially created gas burner that looked like about 20 blowtorches going off at once, for about ten minutes. They were trying to re-create the myth that the tank turned into a rocket that flew 150 feet in the air. They were kind of able to do it by rigging a gun to shoot a hole in the bottom just as the tank started to bulge. It went maybe 60 feet, then started spinning because it didn't have stabilizer fins.

The water heater rocket worked pretty goddamn good though, and morons replace that overpressure valve all the time, because they're morons.
