Why does my 2001 Saab 9-5 smoke just at idle?

[phataus]

I just bought a 01 sa9-5 turbo(automatic) with 127k miles on it. On a scale 1-10 (10 being worst) it smokes black at about at 6 just at idle. I was wondering what it could be. Thanks

When did you change your engine oil last time? It should be ble smoke instead of black smoke.
This is caused by clogged pipes in the camshaft cover, which can produce pressure in the crankcase.
Remove the Ignition discharge module, remove the camshaft cover, clean the 2 crankcase ventilation pipes, Use a 6 mm fuel hose connected to compressed air, If necessary use a piece of wire. Fit the camshaft cover, fit the ignition discharge module.
