I'd say that you have no choice but to pull it and find the problem. Could be a hole in the piston or a broken piston, bad valve, hard to say. I had a 360 that had 3 broken rings in it. Didn't ever know until I took it apart. It didn't smoke out the exhaust but had some out of the breather, sounds more sever than just a broken ring, but I could be wrong.------------------ 1970 coupe restored with the help of my dad. 306 with 650 dp holley, Weiand Stealth intake, headers, mme custom roller cam, harland sharp roller rockers, kb pistons, 10.3:1 compression ratio, pertonix ignitor 2 with matched coil, lakewood bellhousing, 4-speed toploader, and 3.50 9" locker rear. 1986 f-150, 5.0, factory towing package with original c-6 trans
