Blue smoke, but only sometimes? Please help.

[beast_bl]

Alright guys,
Here it is.

I have a 93 TSi AWD, 5-speed, 75kmiles, K&N filter, stock everthing else. I'm losing oil level, not fast, and getting blue smoke, which leads me to believe that I'm burning oil. Here is the tricky part, I only get blue smoke sometimes.

Here's when, after idling/sitting in traffic for a while, I get blue smoke. On occasion, I get it if after start up. But it goes away after a high rpm run, or a highway run.

I have two options, my valve seals, or my turbo seals. If there are any other options, please let me know, or if you think you may know which it is as per the circumstances, please post.

Thanks in advance.

First guess is valve seals. Have someone else drive it, and follow it down a hill with the throttle closed and the vacuum up. Also, check your compression.

does the hose that hooks up into the turbos intakes coming from the valve cover smokes ? looks like vapor

check the head gasket cuz it could be cracked or rotted....also u should consider maybe getting ur piston rings done....mine had the same problem
