I believe he is referring to the cylinders cracking under load and power, not rods beating the shit out of it...
;).

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?

Now let's hope we don't get the rash of cracked cylinder walls that are plagueing more and more DSM'rs around the country with 2.4 blocks.

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.

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. :p


Oh yeah, and I'm going to have Jet weld up the hole in block. Be just as good as new.

Hess had a 2.4.

Was Hess' a 2.0 or 2.4?

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