Im putting a full topend on my 315 (re-nicosil piston ect ect ect) and i have been given conflicting info about ring gapping by two well respected trials mechanics.
one says no need to gap the rings as the tolerances are so fine, and the other say they need gapping to stop the piston nipping, i am undecidad any info or advice would be good thanks.
I didnt bother gapping my she-co and it was totaly fine.
