ok so my car got stolen a little while back. When i got it back it smoked a little and has gotten worse. I checked the oil and it smells like gas pritty bad. So i did a oil change to get the crap out and then pulled the spark plugs.

the spark plugs look like its running lean witch doesnt make much sins to me. I desided to do a compression test and got 150 all across the board. After the oil change it smokes worse than befor i plan on a leak down test. But any ideas that u guy may have if its a fuel problem or coolant the smoke smells like gas to if that help

Is your 02 sensor connected and functioning correctly?
BOV: do you have one?
Is it a recirculating one or are you venting?
Monitor your spark plugs to make sure you possibly don't have a leaky injector?
Do those things and report back as they are crucial to figuring out your dilemma.

my o2 is installed. But with all the oil from my turbo it may be covered. so i will check that first thing. My bov is vented but never had a problem with it. and my spark plugs are white at the tips. But am still going to see if one of my injectors is leaking. hope not cuz the only other ones i have are 550 cc. I will check a few things thanks for ur help i will let u know.
