Ok, I've asked before, and need some more opinions. When I bought my car, after long periods of idle, I'd notice it'd smoke when you hit the gas. Didn't seem like a big issue and actually forgot about it. Last summer I put a 3" catless dp on, and notice after about 1min of idling, sometimes less, it'd start smoking, and hitting the throttle would cause big plumes of smoke. Then it started to do it in the amount of time just at stop lights and stop signs. Then it was pretty much every time I'd accelerate. The intercooler would fill up with oil, probably about a cup or two of oil every oil change. So this is what I did. Thinking it's probably the turbo, but thought I'd start with simple things first.
First I ditched the PCV system and installed a catch can... didn't help with smoking, so it's not the PCV valve.
Winter hit and the smoking seemed to go away (probably mostly just blending in with typical winter exhaust vapor). but it did seem to stop consuming as much oil as it did. Then it started up again.
Earlier this month I swapped turbos, and it seemed to help a lot, but I still notice after idling for a few minutes, it'll put out a significant quantity of smoke. Now, I drained the intercooler, but didn't really "clean" it out. So parts of me says it's just that, but other parts say I'm kidding myself and there's more problems.
Can anyone else give me ideas? Smokes after periods of idle. Doesn't smoke on cold start-up, but will smoke a bit if started after only a short period of being off. Turbo new, PCV system redone. That's about all I can say right now.
