Help! exhaust smoke smoke & more smoke...
 

Every so often when starting the car the exhaust will smoke for about 2 min!! and not thin light smoke but heavy, recently however it smoked for about 5 min. After burning smell is oil burning.. I check fluid levels constantly and do oil changes regularly. She rarely ever has trouble starting and runs great. Whats going on with the smoke? Any ideas as to what is bad or what is going bad?
