I used probe FPS flat tops #p2482f, 4.000 bore, std size. Probe didnt have rings in stock this time so they said any standard ring set will work so I got a set of sealedpower #e251k moly rings 5/64 top, 5/64 second, 3/16 oil ring, std tension. no file fit, std end gap cant remember what it is off the top of my head. Everything went together smooth didnt break any rings or overlap on the expander. Checked dip stick for any marks if hitting crank none visible. Only pops out at 4500-5000rpm or higher. Same shit it did to me last time but at least it didnt blow the rear main like last time. I should have got an evac pump like Jeff said the first time I posted this problem, would have saved me an engine tear down. I will do a leak down but wont get to it for a couple of days I will post the results, probably same as last time. I just cant understand why a n/a engine with new rings and hone would do this again. Pcv appears to be working I have a small oil seperator between it and the intake and there is some oil in it and the pcv is new ford stuff. Just frustrating. Thanks for the reply gearhead.
