Hello,

Thank you for posting at TSN!

When experiencing smoke in the exhaust tailpipe upon engine start may have several possible causes such as the engine mechanicals(Cylinder Head Gasket, Etc.), and enriched fuel delivery, the turbocharger oil seals, and more.
The engine could benefit from a compression or leak-down test at all 4 cylinders which would eliminate the concern for the cylinder head gasket or related problem. Another DIY test would be to run the engine normally and wait until smoke begins to come from the tailpipe and then immediately turn off the engine. Pull all 4 spark plugs and inspect the electrode area for similar color and all matte dark grey. If any spark plugs appear to be of a different color or wet(Oil), there could be a problem with the engine internals(Valve Seals, Cylinder Head Gasket, Etc.).

The use of many turbocharger upgrades on the SAAB 2.0 or 2.1 applications could cause oil bypassing due to the larger compressor wheel which directly brings slower turbocharger shaft RPM at lower engine speeds, idle, etc.

Our findings with many hybrid turbochargers have shown that use of a stagger gap oil seal at the turbine could eliminate potential oil bypassing. The MITSUBISHI TE05 may not allow for this option oil seal although it may be possible to restrict oil delivery by use of a oil inlet gasket with reduced delivery which could still allow for adequate lubrication but eliminate the oil bypassing problem at the gapped turbine oil seal.


Best of luck with your project!,
