Piston to case clearance issues!
A friend, at my suggestion, is rebuilding a 2.2T with the longer stroke and higher compression piston. On the surface all seems well but as he put the pistons on the rods it has become apparent that there is a clearance issue when you rotate the crank the piston bottom juuuuussst bottoms out on the case by the piston squirters ect. I've also noticed that there is a 1-2mm rim around the bottom of the piston that looks ripe for the machining (off)!!. Lets have some suggestions fellas cuz we need help and the case is all sealed up, would prefer not to go in there again.
Cheers,
Nabil
p.s. the case is a the stock 3R '70 T and the pistons are stock 2.2S's and the crank is a 2.4L 70.4mm stoke.
