Well what a way to start off 2007

I wouldnt even think about rebuilding or doing anything with dsms after your luck. It will never be cheaper, maybe short term, but look how much youve spent on this platform already...

Or put his 67 on it and make 550hp. It's a little smaller than what they typicaly use but not much.

Sorry to hear about your car Brian. If you decide to part it out, I may be interested in the shell.

Somebody help me with my engine failure analysis; I'm not seeing how oil and/or coolant issues could lead to an engine crankwalking? Every crankwalk case I have ever seen has been due to faulty engineering, improper machining, and/or improper assembly.

Oil starvation can cause premature wear. It looks like the 7 bolt I just pulled out of a car was because of a pretty badly dented oil pan (the pickup was smashed pretty good). This was causing oil starvation.

Not having the mains aligned properly is one of the common causes for a rebuilt engine to crank walk.

Okay, but how does the premature wear as a result of oil starvation lead to crankwalk? I see how it ruins bearings but I'm not seeing how it causes crankwalk.

Exactly what I thought.

What do you think crankwalk is?? It is the thrust bearing being eaten away. Poor lubrication + clutch being pushed in = crankwalk

I don't think it is crankwalked. Brian just guessed that due to the noise it made, my guess would probably be a spun bearing from the repeaded oil starvation issues and contamination.
