Hey guys, had a real shock this arvo, took the hybrid (2T/3T) out of the car to fix oil leaks, i had preveously did this less than a week ago to fix the leak, but it go worse. Anyway, we took it out, took the sump off and a piece of piston was sitting in the sump  , its one of the couterweights of the number 2 piston. Ive only driven the car twice since it was last taken out due to the amount of oil leaking out (last thing i needed was a yellow). From my knowledge it is rare for this part to fail as it really doesnt have any stress on it. We think that when it was originally machined that the guy either drop the piston or clamped it too tight. The question is, what can i do about it??  during the 2 times i drove it nothing happened, no loss of power or adverse noise. What do you think i should do??
this a large pic ~1.4MB of the piston b4 install, part which broke is indicated

well i would imagine you would replace it otherwise it will not work as it was meant to. if you left it, i would imagine it would wear out or break prematurely.

piston skirt.
from the other site's pic, this thing really looks like a piston from a long stroke truck engine.
i have no experience with a 2/3T.
which side is it from?? both are important, but one side gets a lot more load on it during the power stroke. on all RWD/FR engines, they rotate clockwise when looking at the front(flywheel is counter CW), and the right side gets that load.
it may last a long time, but i wouldn't chance it. probably dropped - cast is brittle.
it also shows the importance of piston balance!!

yes piston skirt, couldnt remember the proper name, i think it was on the intake side but ill confirm that in the morning. Im not sure as to wat im going to do about it, luckily there are no score marks on the bore so block shouldnt need anything done to it. My worst nightmare, ive been babying this engine since we built it not long ago, havnt even hit 5 1/2 grand. But yeah looking like im gonna have to get another piston machined and installed aarrrrrrrgggg

keep engine out of car
strip down
replace broken piston
check other pistons for signs of damage
re-balance engine
replace rings if needed and hone bores if required
