Why is my exhaust smoking?

Asked by Thomas Oct 01, 2020 at 03:16 PM about the 2000 Saab 9-3 SE

Question type: Maintenance & Repair

I drive a 2000 Saab 9-3 and when I drive with
my new oil cap on it smokes out of the
exhaust. I had broke my old one so I ordered
the new one and just taped on the broken oil
cap. When I drive with the taped on cap there
is no smoke that comes out of the exhaust.
Can anyone explain to me why this might
happen and how I could fix it?

What color is the smoke? If it is white, you are burning coolant. Grey pop blueish, is oil burning. I would suspect your PCV and or crankcase hoses are clogged.

It is white smoke but do you have any clue why the oil cap would affect this?
