Cam shaft oil starvation

hey all, i am new to MB and new to diesels. i am learning as i go. i have worked on many cars but diesel is a new game for me thanks for your time.. i have a 1981 240d with a 4sp. seems like it has a lot of power. she has less than 100k but there is a little blow by... my question today is about the cam shaft i did a valve adjust (my first on this type of vavle set up) i am noticeing that the second cam lobe from the front seems to not have any oil on it after running the engine. . with the engine running the oil is squirting out of the oil tube but not on the center of the lobe. the 1st cam lobe is always dripping with oil and the oil squirts dead center.

Dead 81 300D - No Start

Haven't had time to troubleshoot this, but I thought I'd throw out the symptoms to keep me away from any dead ends. 1981 300D, 200K: 1. Started and drove car twice in AM yesterday. 2. Sat for 3.5 hrs and then was completely dead- no starter action, no lights, interior lights work, some dash indications, all dying when cranking attempted. Chattering coming from glow plug relay. 3. Given the totality and suddenness of these symptoms, I'm wondering about a short that just happened during this short interval of rest. 4. Tried jumpering - no response, and the cables got warm at the source vehicle.

'82 300TD lacking power at midrange and up.

Well here is the quick version of the story. I'm the second owner of this vehicle. Have owned it since '94. Have always had her maintained on schedule. She currently has 346K miles on her. The compression is very good. She has always started up easily and quickly. Lately, (and it could be biodiesel related) she seems to lack power at freeway speeds (uphill and passing) especially noticeable at altitude...more than in the past. I have changed fuel filters recently but perhaps need to again. Just changed the injectors and she idles smoother when cold...but shakes somewhat when warm at idle. Have replaced rack damper bolt. btw, it appears my primer pump leaks a little when pumping...can that be a source for an air leak??

1977 300D Loss of power while going uphill

I've heard that 77 300D is not a strong car to begin with, but mine actually slows down and barely makes it up the standard Washington state hills. At the bottom of a hill I could be going 40mph, and by the time I get to the top it slows down to as slow as 25mph!! So far I replaced both fuel filters, air filter, checked compression, compression is right about 330 PSI in all 5 cylinders, which as I understand is pretty good for this engine (or is it?). What else should I check or do to fix this? Any help or ideas would be appreciated. Roman
