I installed a billet rod an a wiesco flat top piston 2.756 standard bore an a dyno cam when installing piston the 2 oil rail rings in the oil expander ring droped in pretty easy, top compression ring I had to use a pop sicle stick is it normal for the first set of rings to go in no problem without a ring compresser ? first part of break in drained oil in a shimmy metal look with tiny pieces of metal is this normal to? refilled with oil an started it again ran for about 15 min drained oil clean as a whistle. refilled with oil , started it again oil started to burn just a lil when I was just giving it a few bumps of throttle so I turned engine off pulled the head in oil laying on top of piston on the bottom side u guys don't think I have destroyed my engine do u this was brand new oem predator that had never been started it already had a fresh hone cut cylinder from factory. please give me some advice if ever happened to anyone. I put 14 oz non detergent oil into motor didn't come up on the check stick so I add about 5 more oz idk if it to much oil or if I have really screwed sum up I hope not
