Baffle mod stolen from another list:

More than likely the compression is low. Cause could be either wear (most likely) or really carboned up rings that aren't sealing. Using Mobil 1 synthetic oil would help in that case.

I don't remember any more, but I wonder if your engine is one that would benefit from fixing a fault in the oil separator, located on the underside of the valve cover.

Here's the fix, passed on by Marshall Booth on another list, should be obvious if you need to do it:

Subject: Re: [DIESEL] Fixing valve cover baffle

The late Randy Durrance documented the "official" MB fix some years ago.

This is usually done when the valves get adjusted. Pull the valve cover off and look at the front edge of the oil baffle plate where it meets the inside of the valve cover close to the oil cap and breather. If it has been fixed, you'll see a gray epoxy covered area. If it needs fixing, you'll see about an eighth inch gap. Clean the area with brake-clean and apply epoxy. Don't use RTV. Don't use J-B Weld (it takes too long to dry and will ooze through the gap. The official stuff was Lock-Tight /NAPA 5-minute epoxy. It does an excellent job and is oil resistant. We used to do this at the M-B dealer in the 1980s. It paid an additional 2 tenths of an hour to do the job with a valve adjustment. Regards,
Randy D.

Make sure that you have the revised flat one piece hose that connects the valve cover vent to the air cleaner and not the
3 piece original one. It's inexpensive - maybe $12 last time
I checked.

Thank you, I saw that post at one time but couldn't find it. I noticed that sealer was just hanging by a thread so I pulled it out and might as well replace it.

Also, it would likely not hurt the engine, as if it fell, it'd travel back down into the sump, and would then either get caught in the intake strainer screen, or would end up on the oil filter.

The oil goes from Pan->strainer->oil pump->oil filter->rest of engine->back to pan (and some goes through the oil cooler if its open) So it'd probably be filtered out first.
The baffle gives the hot gases more time a surface to separate but how important it is to seal up that corner I dont know.

I agree, It proly wouldn't hurt anything ,I just dont like the idea of that stuff floating around in there.
