I have a flathead that is smoking white now big time , last year broke 2 compression rings, 2 weeks in a row never found out why....just replaced rings again I have not checked with bore gauge yet but ring gap is within .002 everywhere in cyl it's checked.... .010 piston skirt clearance. ( like to see .004 but don't think prob)
.005 compression ring
.013 for scraper
.030 on oil
Guides look good .....
Now headgasket was leaking near exhaust valve , I know it will make a ohv smoke but what about a flathead,
Just seems weird , lots of oil on piston and valves when I remove head .
Also broke engine in on electric break in stand
