They are at a slight angle naturally so oil accumulated on left, you can see the mark and about 5mm to the left is the residual oil

Over 12 hours I think they are fine, any advice?
Apologies this isn’t cosworth related but rings are rings!

i know I have guides gone on a Norton commando but unsure about rings

i poured low viscosity oil on the pistons and marked the pistons the left Pot after 12 hours hadn’t drained anything

the right one drained about 5mm from the mark over the same period

worth sticking it back together or new rings?

that was the original plan but can’t get the barrels off now!!!

i think like you say for the price I will just percervier and do them

thanks
