Car puffing out white/blue smoke at idle

[Galant409VR$]

Well today after I got off of work I noticed my car was smoking pruty good when I was on the off ramp. When I got home I let it idle for awile in the drive way and it was just puffing out white/blue smoke. If I rev it to 2k it starts puffing out alot of smoke. Any ideas? I know it could be a valve seal or a craked valve guide or the turbo seal is blown But it makes boost so I dont think its the turbo...the egr valve Is blocked off by a block off plate so it isnt that. I checked the vent tube on the valve cover and thats clean

If i remember right white smoke is antifreeze burning and blue smoke is oil. Possible head gasket? I cant think of anything else that would be bad that would emit both of those.

Does the car still go into boost? could be the turbo seals blown.

turbo still makes boost and it hasnt over heated. I dont have a egr valve and it smells like fresh oil out of the exhaust. Im thing its a valve stem seal leaking of a valve guide craked any other ideas?

[awd-drifter]

my money is on the valve seals with the blue smoke...b/c that's my current issue.

How do I rule out all the other things it could be before I tare into the motor? I checked the turbo and it has very minimal shaft play. The coolant looks brand new and it hasnt over heated. Are the valve seals comon on the 4g63 motors? Could I still drive the car like this if I had too?

Thanks

Check the exhaust side of the turbo and look for oil. Should be able to rule that out fairly easily.
