Smoke doesn't come out while driving on throttle really, but when slowing down and as the rooms get lower it'll smoke a puff out. I changed PCV valves too. Mostly comes out of the right side exhaust and some on the left.

Guessing......Probably not turbo, Due to it would be coming out of both pipes the same.

So If it smokes worse when you first start it up, Valve guides ?, due to oil has had time to leak down into the cylinders, when the car warms up metal expands and the guides seal better, Thinking oil rings, or valve guides, you should be able to do a leak down test on the cylinders might tell you something, heck just a compression test might pin point it to one cyl or another. Or look at plugs, clean them up real good , then go for a drive, re check, you might see the culprit. Not good either way. But again just guessing

the car doesn't smoke on startup at all. Only when it's fully warmed up does it smoke. But it's very light. Until I drive it then let off the gas and a puff of smoke will come out then go back to be being light smoke again.
