Why is oil coming out of your motorcycle exhaust?

This could be caused by a clogged PCV valve, worn internal seals, or worn valve guides. A clogged PCV valve will pressurize the engine internally, which force oil past important seals into the exhaust stream. Likewise with worn seals, oil simply leaks out. Worn valve guides makes it possible for oil to seep down the exhaust valve into the exhaust stream.


Your car smokes from the exhaust manifold area and tailpipe when the car is cold or been sitting up for a hour?

The cause could be worn valve guides. As the engine cools oil can seep down through the valve guides around the valve stems and collect in the head and top of the cylinders to be burned off when the engine is started.

How soon should valve guide seals be changed after discovering that oil is dripping into the cylinders and causing blue smoke at ignition?

You probably won't ever have to change them if you don't want to. It'll just smoke as little when you first start it up. Usually not a big deal. ----------- If your valve guides are worn, then your rings and your cylinder walls are probably worn too. If you fix your valve guides without attending to the other issues, the increased compression may cause problems with the seal of the rings.
