I am putting new split skirt pistons into my RP.
The pistons I had inherited with the car have been condemned by Nick Turley, so they're going. The bores show very little wear, a maximum of .002" above the standard 2.2", but for other reasons I am having the block bored +.010".
On checking the old rings, the compression ring gap is .023" and the oil ring gap is .030", which are way more than the .006" recommended.
My question is, just how critical is the ring gap, and would these excessive gaps explain the oiling plugs I have been blighted by?
