I'm getting a big puff of blue oil smoke on engine start if the car has been sitting as little as 30 minutes. Engine is new, so I don't suspect valve guides/seals. Also, after engine is shut down, there is a clicking sound which continues for 10-20 seconds & seems to be coming from the turbine side of the turbocharger (PT-52). I wonder if these two problems are related. What do you guys think?
