Default Re: Rear Main Bearing Oil Behavior

I reringed my model a engine and now have a rear main leak. Any thoughts on how long it takes for rings to seat? I know it's a loaded question.. I had a couple thou clearance about 1' down between the piston and bore on all 4 cylinders and put new rings on the original pistons (.125 overbore andd don't know of bigger pistons out there). Once i got it running it would leak 7-8 drops per minute at idle. It's down to ~ 4 drops per minute after 325 miles of driving.
