Default Re: Breaking a timing belt

Plus, the piston holes wouldn't have melted edges on them, they'd just be a clean fracture and nothing else (the valvetrain wouldn't have any more energy left after a few good piston hits and it isn't getting driven with a broken belt).
That's a LOT more damage than the engine shutting off at 40MPH because of a broken belt. I see the bent/broken valves, but that belt must have jumped a few teeth a long time before it actually broke in order to blow holes in the piston tops..

Where did that picture come from? What's the real story behind it?

I have an 00 Rio out in the lot that was towed in as a no start, low compression. I have not pulled the head, but with a digital borescope, I was seeing the top of the rod. It will snap the head off a valve in one hit, and then it rides around and smashes the piston crown. The pistons are very thin on these pieces of shit also, and break easily.

Add in the fact that the customer usually sits there and cranks on them till the battery goes dead....and its not hard to get that much carnage in a minimal amount of time.

I took that Rio in on trade on the tow/diagnostic bill, and it is going to the local High School tomorrow morning for its final death lol students will fuck up anything.

If they get the head off it without breaking everything, I will try to get pics of it and post them up. I wish I had a memory card in that borescope (traded up to the one that will record a video or image now from Strap-On)

appears that way. The bellhousing is too small to be an auto on those cars (converter is thick as fuck on them pieces of shit)
