My 1985 GL1200 starts puking blue smoke after about a minute of idling. It is also leaking oil from the timing cover (which I know isn't good). I checked to make sure the crankcase ventilation port wasn't blocked and removed the filter just to make sure. I also rechecked the torque on the headbolts at 41ft/lbs. When I took the heads off, there was some pitting on two cylinders but my local machine shop said it should be fine, so I doubt blow-by is the main issue. The engine is of unknown mileage but from the looks of the insides it seemed like it wasn't very high. I also have a different intake on it; don't think that's the cause but figured I'd let you guys know. I'm thinking I installed the head gaskets incorrectly. Either that or maybe the valve stem seals are going bad. They didn't look bad when I took apart the heads but who knows. I plan on taking off the timing cover next to try to find the leaking oil source, then possibly doing a compression test just to be safe. Any other ideas?
