Hey guys. I'm installing some new piston rings in a B3 engine block from an '89 L, and I had a few beginner questions about what to expect. I'm using the original pistons, and I had the block's cylinder's honed. I purchased a piston ring set from autozone, and the brand is Sealed Power. I measured the gaps of the first and second compression rings, I got about .018". The manual says the max is .012", but my block has 190k on it, with freshly honed cylinders. I reasoned that this would be mostly acceptable, since I trust the fellow who did the machining, and I just put on all new rings. Should I be alright?
From what the Ford repair manual told me, I came up with this gap diagram:
I dunked the pistons in motor oil, oiled the cylinders, and they fit pretty dang snug. Sliding them down to meet the crank was kind of hard, but not horribly impossible. I installed all four pistons the same way, and they all felt very snug. I can turn the crank from the sprocket with a ratchet, but there is resistance. To make one full rotation, it takes about 15-18 ft-lbs of force (which isn't that forceful by my feel) when the pistons are in the middle of the cylinders.
How am I doing? Google searching just made me worry more, lol
