interested if anyone has encountered similar problem please?
i have a 1962 750 atlas motor fitted to domiracer narrow featherbed frame
a problem evolved since fitting manx style oil tank ,
i have oil flooding inlet rocker box running down valve guides
hence james bond very smokey motor after idling hot
easy test to check if rings or head causing smoke is to block off oil feed to head and see if smoke stops
i wish i tried this test before fitting new rings ...duh
i have six start oil pump gears and straight rocker shafts fitted
i replaced valve stem oil seals,checked rocker shafts flats facing towards valves,check factory drain rhs of head all ok
eventually i fitted additional 9mm ID external drain from lowest point in inlet rocker box comes out under inlet manifold to rear of timing cover and the problem seems to be solved.
i use 50 grade penrite oil, max oil pressure is 40psi and when running hot 20psi at 2500revs/5 psi at idle
just wondering if anyone else had this problem and how they fixed it ?
