I would like some advise on my saab se turbo please my car is blowing blue smoke ive been told it is my turbo if so could it of done any damage to my engine

It appears to be a known issue.
Blue smoke is oil.
White smoke is water.
Black smoke is rich mixture.

Blue smoke is probably from the turbo bearings.

Blue smoke is oil burning. You may have a bad seal in the turbo sucking oil into the intake stream.

Blowing blue smoke is NOT an issue with the turbo, it is an issue with either piston rings or valve guides. You need an engine overhaul.

Did you check coolant level???

It is most likely due to worn valve seals and would require engine head removal and servicing/rebuild.

a manual for the car will have the download diagnostics all spelled out for you. You really need the manual to do any work beyond basic maintenance on a vehicle such as this...

I would replace to turbo. To make sure it is the turbo and not the head gasket, remove the air intake to the turbo (not a hard job) and then (with engine off) grab that turbo shaft. Try and pull and push it and move it up and down. If there is ANY play, it's the turbo. If you got 161k out of one turbo, that is VERY GOOD. Normal is 120k or less. There is a guy on ebay that sells rebuilt for about $300. If you do the work yourself (Experienced Tuner) you can save $1k. Else you will have to have a shop do it, usually about $1,200 or so for everything. If you are in the WI area, we could work something out.

WHITE SMOKE MEANS ENGINE IS BURNING ANTIFREEZE.TURBO WILL SMOKE HEAVY BLUE WHEN TURBO SEAL FAIL.ALSO YOU WILL LOSE POWER.YOUR CAR IS TOO NEW.TO HAVE PROBLEMS.YOUR CAR SHOULD BE WARRANTY COVER.TAKE IT TO SAAB DEALERSHIP.LET THEM CHECK IT OUT.

One way to check for a blown head gasket, is to simply smell the coolant reservoir. Pop the cap, and see if it smells like raw gas. Every headgasket, I've diagnosed has had this smell, even if the oil is not contaminated. Another way is to hook up a coolant pressure tester, and run the vehicle for 15-20 mins or so. If the head gasket is blown, the pressure will exceed 15 psi. sometimes as high as 25 psi. If there is oil in the coolant overflow tank, the head is cracked, about 90% of the time.
I'm working on a 03 Saab 95 2.3l t. This vehicle smokes on initial start up, then the smoke disapates, and the vehicle is fine. Another mechanic diagnosed it as bad valve seals. I disconnected the pcv system, and the vehicle no longer smokes. If the valve seals have gone bad, the vehicle will smoke on acceleration. Also if the turbo seals are leaking it will smoke more heavily on acceleration.

What? that's crazy! why wont you take advises from several mechanics? this is the best solution.
