Diesel Engine Specific Aid

I just bought an injector pop tester and checked out my injectors. I have three that pop at 124 bar and one at about 150 bar with a bad spray pattern. I ordered new nozzels but realized I did not know what the correct pop pressure was. I checked in this forum and could not find that information. Any help would be appriciated.

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.

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??

Traveling down the highway, I thought for a moment that the gremlin in my 240D (http://mercedessource.com/node/4065) had suddenly gotten chewed up and spit out the rear as, after the brief ruckus, my horsepower suddenly increased and the engine ran super-smooth. That dream was short-lived as my temperature gauge quickly pegged and I realized that I had no power-steering. After I pulled over and popped the hood, I discovered my crank pulley sitting sideways against the radiator, wrapped in a ball of belts and fan blade fragments. My question is this:
