piston groove
Ok, the 73 FSM manual calls out .0015-.0040 for the compression rings and .0002-.0050 for the oil ring. EDIT: I see by the spec the OP is right on the high side. I’d have a hard time letting that go unless it’s just a dead stocker that won’t see a lot of miles or you just don’t have the money to change the pistons.
