smoking 2001 9-3

How big a cloud? Even my 86 turbo doesn't smoke on startup, so it's definitely not 'normal' for turbos. But if it's only a little smoke, it may not be worth worrying about.

Does it smoke on any other time, like on overrun?

Most likely a problem with the crankcase ventilation. This is common on the B205 and B235 engines with Trionic 7. Saab has sent several service tips to dealers about crankcase ventilation problems. If a clogged crankcase ventilation system is not fixed the oil will be contaiminated leading to a broken turbo and/or broken timing chain. High oil consumtion and oil leaks are also probable results of a clogged crankcase ventilation system.

False.

I have no idea. We don't use that expression here in Sweden.

I'm told by the dealer that the ignition system puts one final spray of fuel on the top of the pistons, for whatever reason, it may be easy start, it may not. This is automatic and cannot be defeated.

The initial puff of smoke you see is due to that. I understand that continuous white smoke or continuous blue smoke (water into the cylinders or oil into the cylinders) is the real problem.

From what I read, some turbos have been replaced at this stage. If this is a warranty replacement, it's a different situation from the "you pay" situation. From the reaction of your dealer, it might still be in warranty, perhaps not.

Wrong, has nothing to do with blue smoke. IF it was fuel, it would be black smoke. Blue smoke is ALWAYS oil.

Cheers!

It was one puff of smoke, not a stream. Could have easily gotten the color wrong, but I think the rest is accurate.

The blue smoke may have nothing to do with the turbo. It may be caused of worn valve guides. Pull out your spark plugs and look at the porcelain insulator around the center electrode of the spark plugs. You see any oil?

No, Saab's doesn't suffer from probs with worn valve guides. This problem is reserved for Ford and BMW owners. ;o))

Cheers!

While it's true that the valve guides seldom need replacing, one of my 900s was at one time very smoky, which was due to valve stem seals not sealing properly.
