BMW valve stem seal replacement
When you start your BMW you see smoke billowing from the exhaust. This is a clear sign of a problem and you find yourself asking, “What causes BMW to smoke?” If the smoke is blue or gray in color you may be experiencing a common problem for BMWs—a malfunctioning valve stem seal. These components control the amount of oil that goes into the valve stem interface to lubricate the valve guide and combustion chamber. It usually fails because of a clearance problem between the valve and valve guide that’s located in the cylinder head. If it fails and bluish or gray smoke puffs out of your exhaust, the seal needs to be replaced.

How do you diagnose a bad valve stem seal?
