Ever sense i put on a brand new full exhaust my car has been puffing out smoke that smells appears to be oil. There doesnt look like there are any leaks coming from the head so i think the gasket is fine, and ive even checked the spark plugs as well. Any ideas of what the problem could be?

 

How long has it been going on? What type of exhaust?

 

its only started to get bad lately, the exhaust is an N1(not Apexi) 2.5 inch piping catback

 

I would go so far as to guess that it may just be some kind of exhaust leak cooking something to cause the smell... have you checked for just a simple leak?

 

what color is the smoke and what model car is this, and year?

 

Ill bet its a 420a... just my guess.

 

The smoke does have a bluish tint to it so thats why i think it has something to do with oil, and Dusty is good cuz it is a GS 420a

 

Allllllright, points for me, lol

 

yes kudos 4 u
and there arent any leaks in the whole thing that i can tell

 

well then i would say your best bet is to do a compression test and see what you get. I think you probably have a bad head gasket, or a seal
