I am curious if someone could say why i have a respectable amount of carbon build up on pistons 1 and 4 but not on 2 and 3? Is this a sighn of anything or style of runing condition.. ?? It is the first time i have seen my pistons since purchase last year any info is good info.

When was this motor rebuilt? how many miles?
Your rings did not seat...but you still need to put in new rings. I cant really see those pics that well...they need better focus and each cylinder needs to be shown with the piston at the bottom of the stroke. Rich |
