Cleaning Oil Seperator 240D
1982 240D
I have my intake manifold off the car right now for cleaning because it is plugged from EGR and I noticed quite a bit of oil in the cylinders 1 and 2 intake runners. The oil appears to be coming from the oil seperator connection to the intake manifold. Is there any easy way to clean this oil seperator to make sure it isn't plugged up and is still doing a good job? I was just going to flush some brake cleaner through it and make sure it was clear of obstructions and then flush oil through it to clean the brake cleaner out. Any other suggestions?

Whats the oil consumption rate?? My '79 240D uses about 1 qt. per 1200 miles and has no oil separator, just mainlines blowby to intake manifold. There's always a puddle of oil at the intake manny that doesnt bother me at all.

I believe the oil consumption has been 1 qt per gas tank for the past 100k miles.

I decided not to clean out the seperator because it looked OK. When I took apart the intake manifold, there was a noticible amount of oil that had run down the first two intake runners. I have also just recently had glow plug failures in the first two cylinders after only 20,000 miles or so. Could these two things be related?

I've been wondering about cleaning out mine too. It seems to be kinda' saturated.
I was thinking of removing it from the air cleaner and soaking it in a bucket of diesel, then take it out and let it drip dry before reinstalling it. Anybody have any thoughts on that plan...?

Maddog, yer usin or losing 1 qt oil per approx 400 miles? Unless ye got massive oil leak something's wrong and it probly aint the oil separator either.
Have mentioned my '79 non-oil seperator equipped 240D w/190k on the clock uses about 1 qt per 1200 miles so you'd have standard of measurement for straight blowby oil consumption in normal healthy 616 engine. 1 qt per 400 miles sounds excessive. How many miles on the engine?? Could be valve guides and seals is where yer oil's going. It's an easy job pulling the 616 cyl head for valve work. Whole thing from nuts to soup probly cost ye less than $499 if professionally done and should easily add another coupla hundred k miles to engine life even if the car's already got 300k+ Awhile ago on this forum everybody wondered why MB diesels rarely seem to last much beyond 390k miles. The answer is simple - NOBODY bothers doing cyl head valve work as regular maintenance at/near 300k when oughta be done so the engine can reach an easy 5-600k miles. |

Rule it out- run the line to a catch tank and see how much oil collects in it.
