Well it seems my OM 617 in 1985 300sd has low compereesion.

Hi Paul....Well it seems...

Hi Paul....Well it seems my OM 617 in 1985 300sd has low compereesion. I',ve located a used replacement engine that looks good. My old engine had the behind the right headlight air cleaner with associated turbo connector elbow, (which had a hole in it!!)....the replacement engine was configured with the lower profile air cleaner attached above the turbo. To make hook up of the replacement engine easier, my approach would be to swap out the entire manifold/turbo charger units....i.e.....replace the unit on the replacement motor with the manifold/turbocharger from the old motor. Looks like it will bolt right on....but am I missing something? Can you decribe for me the differences/reasoning in these two air filter/turbo configurations given they came out of the same year and model of Benz? Thank you, ***** *****.

Mechanic's Assistant: Have you checked the fuses? Have you checked the bulbs?

Humm?....I'm sorry maybe you didn't receive my inquiry? I'm removing a 617 engine and have a question regarding the turbo. Please see above. Thank you.

Mechanic's Assistant: Are you fixing your 300SD yourself? What have you tried so far?

Yes....I'm replacing the motor. I have the new one on the stand and the old one is out of the car.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I don't think so....thanks...

Hi, my name is***** long as both engines are the OM617.951 engines you will be fine. The two different set ups are for California and Federal emissions. I would reuse everything from your original engine.
