Smoking at idle, valve seals or worse?

[QUOTE="Rich B., post: 16691185, member: 202599"] Don’t have a turbocharger by chance? The ceramic bearings seem to leak on those back in the days, valve seals a possibility also. My ‘67 one time I filled crankcase with kerosene and ran a few minutes at idle. Yup, it cleans things up; Marvel Mystery Oil is similar, don’t drive car or race engine while clearing. Oil was terrible back in the ‘60’s. Just breaking out of the high detergent times if I recall correctly. Nope, car won’t start if running straight 30wt oil in January lmao. [/QUOTE]
