Pulled the head and came. They are in great shape. #2 piston is sitting 6-7mm lower than the rest. Apparently I was making to much power for the forged K1 H beam rods. Hope to pull the motor tomorrow and lay the rods on the bench I have a feeling the bend is significant.

It reminds me of that college question
What is the fastest way between any two points on the face of the earth...........
a curved line, a zig zag or a straight line. Lots of people say a straight line but the earth is curved. HAHA.
Given that it has dropped I could drag out some old geometry and trig and figure out the arc before I pull the bottom end but at this point its safe to say that its bad.1989 332IS -S-Fiddy Four-Some weight removed.

So are you replacing rods and keeping the turbo setup?

I do not advise anyone purchase K1 Rods. They did this on 12 psi.1989 332IS -S-Fiddy Four-Some weight removed.

Yeah, google did confirm that. I wonder how their failure rate compares to others. Was it predetonation that caused this?

Very unlikely as the timing was concervative and the comp ratio was so low.Originally posted by Dagamus(NM) View Post1989 332IS -S-Fiddy Four-Some weight removed.

It is all out material failure. I think JE should stick to making Pistons those looked good on disassembly.1989 332IS -S-Fiddy Four-Some weight removed.
