You're full of good news. :) I'm thinking that the MB galley plugs
are threaded, so they are unlikely to come out? I guess anything is possible.

Got home late tonight, so I didn't have time to put it up on ramps
and check the sender and gauge. However, I did pull the new filter
out and it was, unfortunately, fine. The stem O-rings were intact
and pliable, and the top and bottom filter gaskets were in
place. The oil canister was

I forgot, is this the E300?
Do those things have piston cooling jets?
Seems like 1995 was not a turbo year.
If a cooling jet fell off, I wonder how much
oil pressure would escape from the hole?
Another possibility (on any engine) is loss of

This is the E300. It is non-turbo, but does still have the piston
cooling jets. However, I do not know as they can fall off. I think
they are just a specific sized hole drilled in existing material, but
I may be wrong.
I have not detected any loss of oil anywhere, including into the

pan and scrape the crud out. Guess what I need to do on my tractor this fall?

I don't think it's anywhere near that dramatic. On my '83 300D Turbo

Thanks for the suggestion. Am I correct in assuming that the low oil

Yes, completely unrelated circuits, except that they do share grounds.
