(85 380SL)

I got to work with serious valvetrain noise, both sides. Looked under the oil cap and only drops were coming out of the oil tube hole visible to me. On my 560 and on this car I know I should see a stream. The car was running normal oil pressure and the oil was slightly below the halfway mark between the red on the dipstick.I put in more to get it near the top of the "upper" red guide. No change. Mileage is now 111K. Cam lobe I can see is not scored or damaged(yet).

Any ideas would be appreciated. I brought it home, parked it, and can't take it apart now because its hot. I will after work, though.

-MAYBE an oil tube popped off (again)? Both sides??? See below.
-Blockage in engine (unlikely that plastic guide chunks are a problem, see below)
-cam oiler tubes blocked with sludge (both?) Unlikely, the engine is very clean and the oiler tubes were cleaned when the fittings were replaced. It was very clean and unblocked before cleaning, but I did it anyway.

History of engine:

Bought at 95K with serious knock/banging on RH side
Upon purchase, replaced timing chain, upper guides/, tensioner, tensioner arm. I don't think this had ever been previously done. The old guides were not chipped or broken.
Knock was due to popped-off oil tube fitting on RH side, unmaintained for several months of driving, leading to multiple RH cam lobe wipeout; all cam followers as well as RH cam were replaced properly with break-in lube, etc.
Oiler tube fittings were replaced with new and installed properly all the way in seats, and were never re-inserted (which would wear the barbs out).
Oil changed while in my posession at 3K intervals. The oil is clean and the filters look pretty good when replaced.
Oil pressure is 2 bar idle, 3+ bar off-idle.

Needless to say, I'm worried. I thought that this problem was put to bed.
