Another oil separator question (old 240D)
It's not a great pic. but see the piece at the top arrow? I believe thats the current oil separator, which is letting too much into the intake. Want to mount the one from a later model 240D, but I'm confused about what's up with that pipe that I think the oil drains through. The later one drains to the sump, so will I have to cap these drains? I read in another post about oil mist making it through the separator lubing the turbo, any issues on this engine?

I know the 240D engine does not have a turbo, so there won't be any issues with oil vapors lubing the turbo. There must be a vent/breather to the atmosphere. Preferably between the valve cover and the oil separator. As long as you have a line from the valve cover going to a oil separator, and another line going from the bottom of the oil separator back to the sump you should be fine. I would cap any stock lines that you don't use.

No can do unless you put the oil pan from a later 240 on it. The early (615 engine) 220/240s only have that vac valve on there -- diverts the oil/blowby stream to the intake butterfly at low vac and into the intake manifold at high vac. There is no drain back to the pan.
This means they have higher oil consumption than the later ones. I believe you can retro-fit the mainfold and oil pan, but you will have to design the correct throttle/tranny linkage as the W123 (which has the 616 engine with oil separator in the air filter housing) has a different thorttle/ tranny linakge.

So those aren't oil drains. At first, just to see the effect, planning on collecting the oil and not hooking up a drain to the pan yet. On the 123 240D that's the donor car, the separator isn't in the air filter, but is a separate unit off to the side. Anybody else out there done this? For Peter, I have thought about swapping the entire intake to get away from the oil bath filter, but there's no venturi tube in there for the pnumatic governor in my I.P. plus all the linkage swap, so thats on hold.

Oil separator
240Dnewbie,
Go quickly down to yor local pick-n-pull and get one of the 300DT or 300D air cleaner housings with the oil separator built into it. Install it on your car. attach a rubber hose to the bottom out let with a hose clamp. Run the hose down to the area just under and behind the radiator. Acquire a quart size empty plastic, peanut butter jar. Buy a barbed hose fitting a the hardware store and install it in the peanut butter jar lid. Connect the rubber hose to the barbed fitting on the lid. Now make yourself an "L" bracket or purchase one at the same hardware store. A couple of bolts through the lid into the bracket and a couple more bolt into the area near radiator bottom and you now have a collector bottle that you empty back into the oil filler cap. Lid stays bolted in place and the jar body unscrews easily. Wear rubber gloves when emptying jar, can be messy. Occasionally I forget to empty mine but oil spots on the garage floor warn me to empty jar. Eventually one can get a second small sub oil pan and install a connector and one way valve and you never have to lose your ministerial dignity again by crawling under the car to empty the peanut jar. It works!!! This commercial brought to you by Skippy Peanut Butter. Ben

I don't think it will fit. My 240 has the oil bath air filter off to the side, so no mounts on the intake manifold, and can't swap manifolds because it needs the venturi for the pnunatic governor that later models don't have.

So!
240Newbie,
So, make yourself another bracket and mount the 300DT or 300D filter body on top of the fender well. Ben

Sorry, guys, the later air filter won't fit even if you change the manifold -- inner fender is much closer on the W115 than on the W123, besides the problems with what to do with the oil that drips out.
I'd just leave it alone if it isn't dripping oil and live with the consumption problem unless and until you want to attempt the linkage setup. This isn't going to be easy. Peter

YES! It's totally different. Going to be easier to fab a bracket for the later style 240D seperator. Here's some comparison shots...

How about sideways with induction cowling sticking out the hood?
