My bet is still the ringlands. Did you check the oil pan for any pieces of floating metal? </TD></TR></TABLE>

i just pulled the pistons they look just fine to me ?? i wish i had a digi cam so i could show you but there were no evident cracks, i still am stumped on the tapping/ knocking noise i heard ? wow! the rings are all intack too.

 

does this sound odd to anyone? what the hell else could it be making the noise?

 

Any opinions?¿

So does this mean this pistons is garbage and causes you to lose compression? I've seen pistons where the wrist pin is deeper into the piston. This is used for people who want to run longer rods. (Couldnt find a better pic but this will explain what I'm saying)



Not the ringlands. Ringlands breaking is not that common at all.

Tell me this wouldn't cause excessive blow-by...

 

yeah it was my ring lands .... i dropped the piston by accident today and the ring land that was broke fell off, i looked at that piston like 20 times and never saw it until today


what causes that to happen ?

Detonation. Cracked ringlands can sometimes by difficult to find is the fractures are hairline but the symptoms are always the same, loss of compression and excessive blow-by.
