piston rings: what's right?
Posted: 24 May 2021 14:40
I know there are many piston ring threads on here, but I can't find an answer to my particular question, so here goes.
I've got the old pistons out of a spare Strada engine I have to put into my re-furbed engine (eventually).
Both pistons have identical rings.
My old photocopied Harglo workshop manual shows that the front piston should have a spring on the oil control ring (bottom) and one of these (the rear one) is broken
Neither of the pistons have this spring on them.
Mdina Italia lists some rings, but they do appear to have springs on them, but of a different design to the Harglo image.
I'm getting the barrels honed, and measured, and, if all is good, I was going to just fit a new set of rings.
Does it need a spring? are the Mdina rings interchangeable?
Cheers!
