Yo guys
i was running a turbo bluetop in ae86 ... it went kaput ..was still running but heaps of smoke was coming out of oil breathers on head.
My question
i pulled the engine apart and was sure it would be a piston skirt broken ... but ... all pistons were fine bar one that had a little crack in it on the skirt ..but it wasnt the one giving the pressure test reading of 100psi all the others were 200psi ...what do you guys think was the problem ?
my second guess is rings ..but could something have run a muck in the head ? valve seats ? ...
how do you check to see if rings are worn ?
and what tests can i do on head myself to check whats wrong ?
also 200,000kms motor ..and bearings were still mint
