91 350SDL - are there Monarch nozzles available?

I have converted an 83 300TD and am quite happy with this car. I put Monarch nozzles in the injectors.

I have a 91 350SDL (118K) that I want to convert with a two tank system. I have it installed and checked out getting oil from the tank in the trunk where I have the WVO pump. No problems getting oil all the way through the system. The air has been pumped out.

I checked the WVO tank and made sure air could enter it as I pump WVO out of it.

I switch over when the oil is about 140 degrees and the engine soon starts chugging and then dies. If I switch back to diesel and crank for a bit, then I can restart the car.

Even if I switch over when the engine is warm and the car is just idling it is not very happy. (unlike my 300TD).

instructions for installing new door adjustment switch on '82 300SD

I ordered this kit from Mercedes Source. You have to solder in the wires into this kit for a new electrical switch for the drivers power seat adjustment. But it didn't come with instructions. I have done soldering before but I would like a few tips on how to do this right the first time without messing anything up. For one thing, there is no crimping involved right? Aside from a soldering iron, I shouldn't need any special tools right?

Engine won't shut off instantly/'82 300SD

It looks like I might have a vacuum leak. After turning off the engine via the steering column the engine still runs for about 2 seconds. If I press on the diesel pedal the engine will actually speed up a little then shut off. I would would like to know: Is the system under positive pressure or negative pressure? How do you test the fuel pump stop diaphragm to see if it holds pressure? Also the door locks still work but the brake booster isn't as effective recently as I have been having these problems.

91 350SDL -- oil in the intake manifold

I found that there is a lot of engine oil droplets coming into the intake manifold...and think it must be bad oil seals in the turbo.

I am working through 350SDL issues and found the solid hose broken that goes between the air intake (pressure side) and the mechanical accuator that opens the waste-gate. I am assuming that this has caused the previous drivers to drive it over-pressured. Would that impact the turbo oil seals so that they could now be leaking into the intake air? Are there other things I should check knowing this has happened?
