Yep.

Yeah, it looks like the wrist pin seized up in the piston. Notice the bluing on the end of the rod and there are small cracks in the piston around the wrist pin. Nash, is the #3 cylinder the one with the broken oil squirter?

It is 2.0ls also. Mostly seems to be guys making 550whp+ on either block. Or at least on 6-bolts.

I would guess it spun the rod bearing then cut oil off to the wrist pin, thus breaking the rod etc.

Bzzzt... The rod bearing is perfect, the rod falls back down just from gravity when you pick it up. The wrist pin just seized for some reason.

It looks like it to me.

The pin is thermal fit so it is intentionally siezed The piston pin gets oil off the cylinder wall, the rod journal just puts a stream of oil on the wall as well. It isn't a direct feed or only source for the pin.

Good luck with that, let us know how that holds up.

Hess had a 2.4.

I wonder if cryo treating blocks would made a significant difference with the cracking issues.

Wow, I didn't think that thing was still running. Did you really push 530HP out of it? It says 91 on the Elite list and that was a 90. Anyway, excellent work with that car Andy. Best of luck with your next project.

Thanks again for such an awesome deal! The car did end up putting down 531 fwhp, not bad for stock internals. That was the best $360 I have ever spent!
