Ring Gap P1
Hi
I am building my P1 back to a stock engine using the old pistons with new NPR piston rings.
My old 1st and second ring gaps are both 0.30 ~ 0.40
The NPR rings are measuring 1st ring 0.25 ~ 0.30 2nd ring 0.45 ~ 0.50
Does this seem right ?
The car had covered a mere 22,000 miles
Thank for any help.
