Symptoms:
The classic symptom of bad valve stem seals is, if when starting the car,
after it has set for a little while (say over night), clouds of smoke appear
from the exhaust and then stops after a few seconds. What happens is, while
the car is setting, oil leaks down the valve stem past the seal and
accumulates in the cylinder chamber. When you start the car, that oil is
burned off out the exhaust pipe.

Bluish/White Smoke from tailpipe at startup.

What should in a case like this?
