Interesting problem with RD28T.

[Shaunous]

Hi everyone! I'd like to get your advice. As there are not so many cars like mine in my city I meet difficulties with service and repair information.

The problem:
After my car has been idling for 5 minutes or more, the exhaust starts to have blue smoke with smell of burned oil, after a few kilometers in city traffic the smoke is disappeared.
If vehicle stands in traffic jam for 10-15 minutes the blue exhaust appears again after start of motion.
The oil consumption in this mode is 100-200 g per week. (I replace oil every 7000 km. and use this oil - http://www.liqui-moly.de/liquimoly/p...oiladb=web.nsf).
But! If I start engine and began motion immediately I haven’t any smoke and oil level is not falling away. (except traffic jam).
PS. The turbo compressor is wet by oil.

Your turbo compressor/inlet side is wet? The way you are describing sounds as if under load it's not burning oil, can you check if the exhaust side/turbine is wet with oil, I know this is a pain, or even check if the compressor/turbine shaft has any movement, up/down movement isn't so bad if its minimal, but it shouldnt have any forwards/backwards movement.

If it is only the inlet side of the turbo that is wet, trace where the oil is coming from along the inlet as it may just be the PCV filter letting to much oil into the inlet.
