Blueish smoke from exhaust??

[SleepingTsi94]

After car is started for 2minutes lots of smoke will come out of the exhaust. Then I'll take off and there will be no smoke. But if I sit there and rev it up a little bit it puffs it out again. Could it be the turbo seals, pistons rings, or the headgasket?

Sounds like valve guide seals to me. If you stop in traffic and take off after a minute does it smoke. If yes that is usually a sign of valve guide seals going. If it was your turbo seals youshould see oil in the intake hose. Pull the hose off your turbo and see if there is any oil. Keep us posted. Travis

Motor was rebuilt 4k ago by Kar King, but tonight i'll have more information about the blowing of the smoke. I'll have someone follow behind me, and so forth.

+ 2 on the valve seals, my car is doing the same thing right now. I picked up this stuff called 4 cyl engine restore, it comes in a silver can that looks like a soda can, helps bring up compression, helps with valve seals and small oil leaks. Ive used it for a few oil changes and it has helped with the blue smoke. Though there is no mechanic in a "bottle" it will help for the time being.

I had a compression check done maybe a week ago and got 145 across the board.

Do it again to see if there is any change?

Was it a cold or hot compression test? Did you hold the throttle open?

I didn't do it my self. I had a shop do it here in town. Which one should I look into doing. What do you mean by holding it open?

You'll want to do a hot compression check. Go out and run the motor until it's at operating temperature, then check it. To 'hold it open', just mash the gas pedal to the floor while you're cranking it.

Here's some info on doing a compression test. http://www.dsmgrrrl.com/FAQs/compression.htm

KK gonna be doing the compression check here soon. I just took it out to warm it up to do it and it drove fine. And once I came to a complete stop it started smoking. And I let and that was the end of it. Now im back out home with it ideling outside and no smoke is coming out. Still on for vavle seals? And will the compression check be able to tell me?

Well did the compression check and got good numbers all way across consistent. So im guessing my bets on the turbo. I pulled off the intake from turbo and there was some oil once I put my hand in there.
