My Bonneville has an oil leak, and I'm not quite sure where it is. There is no dripping on the ground, and I'm pretty sure it is not burning it, as there is no smoke in the exhaust or oil on the plugs. Although, I do occasionally smell something, like some oil dripped on something hot on the engine. Anybody have any ideas where it could be at?
Didn't you also identify in some prior threads that the valve inlets or something to that nature is a source for oil loss with no oil found on ground or seen out the exhaust? I have a like condition with my Bonny and my valve cover gaskets are ok.
With no outside leaks of oil found, and missing a high amount of oil and not seeing much if any smoke, valve seals can be the problem. They only leak when the car is parked and not running. And only leak a small amount.
