need some fast help, Doing valve adjustment!!
i am in the middle of my valve adjustment on my 240D. i just took the valve cover off, and found something interesting. the cam lobes are clean, and with that i mean there is no black oil on them. they almost seem dry, with only a super minute layer on them, but it seems dry.
yesterday i changed the oil to Rotella Syn 5W 40, and i drove it about 5 miles. so would this explain the clean cams. i mean they look dry. i have a pic below, should i be concerned? also while i was under the car, i took a picture of my linkages? i have a 4 speed, and when i shift i hear a light metal clinging, like there is some loose gap when somewhere when i am shifting. took pics of the linkages underneath, there is a large gap between where i am pointing, kind seems like there is supposed to be some rubber grommit in there to keep it from being loose. can someone help me ID some parts? thanks everyone

Looks like you need new shift bushings.
I'd be worried about the cam. It almost looks like there is rust on starting to form on the lobes. It might get a little messy, but I think you should run it for a few seconds with the valvecover off to see if there is oil coming out the rail. It should look like this: |

i mean can it be that clean because i just changed the oil (ie not black yet), and i did not turn it on in the last 18 hours?
there seemed to be a very very small film of oil on it.

Oil drains. I see nothing wrong with a clean cam, and shiny lobes. However, clean as they may be, they are not shiny....looks like rust as ForcedInduction mentioned. Does the surface feel smooth? Smooth or smoother than glass? It should.

it does feel super smooth, i think i will do the valve adjustment, put everything together, run the engine for 1 minute and then take the valve cover off and check it out. that way i can see if everything is lubed up. now the valve cover had oil in it, with that i mean it was oiled up totally on the inside. so that might have just been a fluke.

Did the car sit unused for a long time at some point in its recent history?...
That might explain the spots that appear to be rust on the cam lobes. I think your idea of running it for a couple of minutes and then pulling the cover again to be sure is a good idea. However, if it was running fine beforehand, then I don't think you have much to worry about. Mike

I assume the 240D is the same way, but on my 300SD I can remove the oil filler cap while the engine is running and see oil being squirted on the camshaft from the spray bar. It's more of a 'stream' than a 'squirt'

Blowby question...
Quote:
On mine, I get some oil from under the oilcap (even though I've flipped over the oil cap seal) - is that typically caused by blowby as well?!

A bit of wheel bearing grease on the seal will also stop any oil getting past the cap. |

I haven't tried it with the plastic caps... I don't know if it will work on those or not. Mike
