Smoke from exhaust with no load
#24
I would say those results are pretty good and a big relief. All losses were past the rings. According to every piece of literature out there anything under 10% is considered excellent condition. Keep in mind, ring gaps are set relatively loose on this car as they should be so some blow by is expected.

So it's no better. Used a qt of oil on my way to work, it's weird because it doesn't even smoke much. Pulled the plugs, still a pool of oil on the pistons. I'm honestly done, I'm not gonna sell the car but I'm gonna put it away till the winter when I have time to do another rebuild. Pretty much gotta be the oil control rings at this point,

83.50mm Arias pistons using the Arias supplied rings. I gave the pistons to machine shop for measurement but I assembled the bottom end. Not sure what p2w measurement he went with. I don't recall but I believe I set the gaps to 0.021. I should know better but I'm second guessing everything now and wondering if I installed the scraper rings all upside down. I obviously make the same mistake on all 4 cylinders whatever it was. I have a lift in the garage and a cherry picker so it isn't the end of the world to pull it apart, I'm just tired of working on it although my wife is insisting I should just fix it. I was gonna swap in my 6 speed soon anyway so I guess pulling the engine is ok. I'm honestly just glad I'm not gonna have to pull the oil pump, crank, water pump ect.. just checking and replacing the rings isn't nearly as much work as the full rebuild.

Look at Arias end gap recommendations for oil ring: 0.20" per inch of bore... Guess it was in spec
