Those bearings aren't too bad.

But hey, while its out and apart its cheaper to replace them :).

The exedy is a heavy duty unit - based on the part number

Good ole broken ringland.

Looks like my guess was reasonably accurate. Seems to be the first thing that lets go on the factory engines when you start to give it a bit.

Im surprised thats its a heavy duty clutch when I went to first look at it I couldnt take it for a test drive because it needed a new clutch and they said they wouldn't be putting a hd one in.

Finished stripping the engine today and found the no 2 piston is also cracked. Not sure why it didnt show up on the compression test.

Should be pickin up a 5s bottom end Monday or Tuesday.

clutch disc may be better material etc but doesn't mean you have the heavier pressure plate to match?

So which pistons did you root, 2 and ??

2 and 3

2 is the closer one in the pic with only one small bit missing

Great to see you have been doing everything yourself, very cool indeed. Looking forward to this build!

Exactly what happened to my stock gen2 bottom end. Except I had three dead pistons :(
Good luck with the build!

Interesting... Gen 3 obviously. Leaning out of inner two cylinders causing detonation was a well know problem with the gen 2, think the gen 3 made some slight improvements, perhaps it is still an issue? Weren't running any individual cylinder trims?

Obviously this sort of problem is hard to detect without being able to measure the AFR on each exhaust runner, or alternatively, exhaust gas temperature. To avoid the same happening again, perhaps have some exhaust temp sensor bungs fited to the manifold and make use of them when tuning to dial in some trims to individual cylinders if required.

Your tuner is competent?
