As a mechanical engineering student I have some sort of weird fetish for catastrophic mechanical failures.

Ooooo goody


My GTP's original block, was a little too low on coolant and a little too aggressive on timing. First track outing.


Friends car. Small bolt accidentally left in intake during assembly. Ran for about 5 seconds.


Torque! I didn't think those cute little tires had it in them. First track outing in the Corolla.


2000 Catera. Bought with jumped timing belt.


Note to self: Scirocco radiator does not have the cooling capacity for a FI engine of twice the displacement.


Valve dropped in the GTP on the highway. Unsure of exact cause but have a couple theories.

This is the best I have, it's part of a generator set. That's the radiator on top, and in the middle is a vertically mounted electric motor that drives a five blade fan. The air exhausts out the top of the enclosure. Well, it did until the fan got itself broked.

I was told they were incorrect lug lengths for the studs and simply weren't long enough, or something to the effect.

1/2" Lug Nuts on a M12 Stud.

Was able to get them on and tighten them (stripping the thread in the process).

Fixed that for you.

We have these handy video tags now that allow YouTube videos to be embedded. I think you have to enable it in your settings though.

That's wrong!


Maybe it's because I've been watching horror movies instead of sleeping, but all these pictures of mechanical carnage suddenly made me think that the block only exists to keep the more murderous parts of the engine from breaking out and killing us all.

But that's just silly.

An engine block can twist when overheated. Combine that with torque and you can easily bend an engine block.

I saw something similar years ago in person, I wish I had photographed it - a VW 5-valve that had a timing failure of some sort, and mashed all of the valves into the head. One of the valve heads had broken off of the stem and embedded itself firmly (at about a 70* angle) in the valve seat.

Cast metals can be made hard, but not tough. And I am pretty sure they aren't forging blocks now. Hell, a block's heat point is past the burning point of oil.

My guess is mild warpage is what the fellow is talking about.
