I pulled the engine (617.950) from my '79 300SD to transplant into a better body. It's got 245K miles on it so I'd like to replace the sensible stuff while the motor is out of the car. Right now I'm thinking for starters the timing chain + slide rails and
oil cooler lines (weeping like crazy).

What I'm not sure I want to do or not is the turbo which has a bit of oil in the intake when I pulled off the air filter assembly. Is this an indication of a failing compressor oil seal or from blowby coming out of the valve cover ventilation? Do I rebuild while I've got it out? It's a garrett t3 I believe (haven't looked at it real close yet).

Any other suggestions for things that should be done while it's out would also be appreciated.

Thanks
