Smoking g12

Post by nigelpreece »

I have a 1959 g12.. Runs fine but does blacken the timing side exhaust.. Don't see any smoke normally. Today, after standing for 2 weeks, it smoked from the same pot on startup and dripped oil from the down pipe /exhaust union. Any thoughts?? Value guide. Tight valve? Just done 20 miles and running fine. Cheers nigel... Might be wet supping?

Wet supping is drinking beer! You obviously mean wet SUMPING. In only two weeks there SHOULD not be too much oil in the engine cases. I would have thought if it had wet sumped that it would have tried to get out both sides. Personally I would suspect something is wrong on the timing side. How long has it been together? Have you done many miles?
