Does anyone have the story on the GM truck? That's way beyond any radiator failure, unless he was using liquid propane as a coolant.

How about horrible failures of a mechanic? The 3 inch PCV to intake hose for my neon was $32, so I rerouted it instead of paying the dealership to send me the wrong part again. Click here for the full 1600x1200 image.

Blue hoses have been shown to add like 4 more HP but you can kind of negate the loss with a sweet braided stainless hose sleeve.

I think he was talking about the sheared off bolts that hold the wheel that was there on. Unless your conversation just went over my head.

wow that makes me glad I torqued down all the caps on the rod's when I was helping my dad rebuild one of the 1271's on his boat. Nothing more fun than laying on your back, just above the bilge, catching rods as my dad drops the cylinders into place....

Yup, if they stay in long enough it will start to turn into ash but they usually foul to the point of not working before then. I have to pull and clean them every few hundred miles, I'm pretty much just seeing how long an engine can run like that at this point. Being an AMC 258, I'm not holding my breath.

Try getting a spark plug anti-fouling adapter most auto parts places have them if you ask. As I understand it its a sleeve that goes in first and helps prevent the poo poo building up.

oxbrain posted:Run hotter plugs. That's my plan next time I get paid, but I'm making these plugs last a little while at least. The biggest problem areas are when you take too long cranking it, and if it idles too long. I would need one of those anti-foul for each cylinder. A few are worse than the others, but they're all bad. The carb running rich doesn't help but my hands are tied there, I have a million projects going on at once and I'd rather this thing runs poorly instead of not running at all.

Am I stupid or is an anti-fouler a washer that makes the plug a hotter plug by keeping it from threading in so far?

ab0z posted:Am I stupid or is an anti-fouler a washer that makes the plug a hotter plug by keeping it from threading in so far? A tube that moves the plug all the way out of the cylinder head with just a small, like 1/4" hole where the spark and mixture can meet. Effectively an oil shield, but kind of a hack.

IOwnCalculus posted:If you're fouling plugs that quickly, "performance" is defined by "is it running". Yeah, by that point having optimum ignition in the combustion chamber is a drop in the bucket. It's been knocking for thousands of miles now, which makes me think it's just pistons slapping around in the bores instead of a bad rod. Doesn't matter to me, as long as it goes down the road for a while longer. I'll try and get pics once I finally tear it apart. I'll have to get some mics and stuff so I can see just how hilariously out of spec this engine is. Maybe I'll put my protective case on my camera and take video of the exhaust pipe during a cold start later

Well, its not really automotive, but it does involve a centrifugal pump, so its close enough, right?

And don't worry, if you've read any of this thread, there are a lot more things in here than just automotive. But who cares, mechanical carnage seems to be very welcomed here in AI.

Negromancer posted:holy poo poo. I need the story that goes along with that picture, and hopefully more pictures of the carnage. Unfortunately, its a mystery to this day. One of our inspectors went out to a customers warehouse, and they noticed that the pump casing was cracked in half like that. The rust is just from sitting outside our warehouse for a month or so. Both Aurora and the seller's technical experts came out to look at the pump, but they couldn't figure it out either. For those that don't know, that's a vertical in-line fire pump, and it had only been installed four years previous. I have other pictures, let me see if I can't host them. Here's the impeller with the discharge attached.  Click here for the full 600x800 image.  Click here for the full 600x800 image.  Click here for the full 600x800 image.  Click here for the full 600x800 image.  Click here for the full 600x800 image.  Click here for the full 600x800 image. No one that's seen this has ever seen a pump hosed up this bad that wasn't caused by an improper installation, or a large rock from an unflushed underground connection. This wasn't caused by any rock, and there wasn't any cavitation.

You should be able to analyze the cracks to tell how they were caused; there are always tell-tale signs (though the rust may make them difficult to spot now). I suspect casting defect and fatigue.
