what is FSM (14-100)?

FSM = factory service manual. Mine isn't an official copy because I bought it before discovering that MB sells the same thing for half the price. Mine seems to cover a bunch of different models and years, and claims to cover the 79/80 TD (non-turbo) models too.

14-100 is the section of the manual I'm referring to.. in case you or others wanted to look it up and comment on its applicability.

As for mismatch, near as I can tell from my manual, it sounds like MB offered an option or field upgrade to change the air cleaner from a oil bath version to a dry paper-element one sometime in that model run. I'm wondering if the replacement engine had an oil-bath air filter and the original had the dry paper filter. I can totally understand why they would keep the dry over the bath during the switch. Unfortunatly my manual doesn't describe the upgrade nor where the oil separator on either version drained to.

I know on my car, the separator drains to a tube that connects into the side of the oil pan. But it's a newer model.

If you want, we can get together sometime and compare cars.. maybe see if we can figure out where your separator is supposed to drain to.

I'm also wondering if maybe there's a leaking plug in your oil pan that accounts for a lot of oil lost to drippage. With all that oil dripping onto the manifold, you probably couldn't tell if there was a major leak somewhere else.

Sounds like you need that pan and the tube that went int he hole to complete the swap. I just hope you don't have to pull the engine to make the swap.
