Default Smoke from exhaust - exploring options? - 03-05-2018, 10:46 AM

Hey everyone!

Last post I made was in November about my misfires in the engine, but new spark plugs remedied that!

Now I'm having a little trouble with smoke from my exhaust, and I'm hoping it's as easy of a fix as the spark plugs for the misfire. Most of the smoke is coming from the left pipe, and I can't honestly tell what color the smoke is, or what maybe to look for. I can put up a video later! <- Also lots of carbon in the exhaust tips.

The previous owner put in Conventional 10w-30 in it, just a quart, and that's what I had to drive it home on. I'm hoping that since he clearly didn't know what to put in the car, that he might not have changed the oil filter regularly, and an oil/filter change will fix the smoke, does this sound like it this could fix the issue?

Thank you!

Does it smell like fuel or like oil? To be honest it looks normal to me considering it is a cold start and it's running rich.

Where are you located? Was the car kept inside or outside during winter? Do you have *** less d p's? Does it smoke when the engine is warmed up and if it does is it still smoking mostly from the left pipe?

I'm in Indiana! That start was around 50 degrees Fahrenheit. It smokes a lot more under heavy acceleration, and was kept outside.

Based on BMW recommendations 10w30 oil is too thick for this engine when it's cold. I would do a compression test first
