Diesel Engine Specific Aid

79 240d oil pressure ?

I'm going to try this question again. My 79 240D just got a new (used but better than it had) engine.
The engine starts good when cold (20 degrees now) and has good power for it's age.
I'm running Schaeffers 9000 series 10/30 synthetic. Had good luck with this oil in other diesels we own including old dodge cummins, and our new 09 volks 2.0 tdi.
And maybe what it's doing is no big deal, but it doesn't seem right.

1977 300D no engine turnover

as if things couldn't possibly get worse from what they are. I just bought a can of engine starter at autozone, the guy there told me if i sprayed it in the intake and the car started it need glow plugs... well i did what he said and soon after my car started and ran. since my car set about a week without running i went and drove it about 5 mile when it started overheating.

1984 300D Power Loss... on Bio?!?

Hi there Forum Fiends, I'm helping a friend try and troubleshoot an issue he's been having with his '84 300D-T losing power while running biodiesel versus petrodiesel. The biodiesel is good quality ASTM-certified commercial stock, so I don't think fuel quality is the issue... A mechanic wanted several hundred bucks to open it up and diagnose! I'm thinking it can't be that complicated... Can it? Does anyone have any theories as to why this would occur?

75' 300D getting rid of A/C compressor

Hello - I have a 1975 300D with an A/C system that doesn't work (and I don't need anyways). I want to remove the A/C compressor because it gets in the way of reaching the alternator. I run Veg and am considering putting a diesel start up tank (fuel cell) in it's place since there is lots of room on that side of the engine and it would be easier than putting a tank in the trunk and running hoses all the way to it (if the york A/C compressor wasn't there there is plenty of room) So . . .

1984 300sd won't idle and hard start

Recently,

My car has been acting funny. It will only start if I give it gas and it won't idle to save it's life, I have to keep my foot on the gas at stop lights.

I replaced the stock fuel filter, air filter etc. I've read that it could be the ovp, but the socket is empty in my fuse box and I can't find anything that resembles it anywhere else. My dash lights (Brake warning etc) do come on at idle until I give it some gas.

Any suggestions would be appreciated.

1984 300D Turbo Injector heat shields

I just bought a 1984 300D Turbo Diesel with 204,000 miles and it ran great on the 700+ mile drive home getting 25 MPG with lots of power. The injector return lines were leaking a little so I got the Bio hose kit from Mercedessource and installed it last weekend. I pulled all 5 injectors out (keeping them in order) to get the old lines off (they all broke when I pulled on them) and put everything back together per instructions, but minus new heat shields. I now have the following problems that were not present before.

300SD Adjusted valves by the book, now won't rev ???

n/aI am new to Mercedes and just bought a nice running 1982 300SD. I wanted it to run nicer so I adjusted the valves. Now it acts as though the throttle is not connected, but it is. Can't hardly get it above idle, even when I push the throttle rod at the injector pump. Starts easy, sounds good,
no smoke. I rechecked the valve adjustment, it is spot on .004 intake, .014
exhaust. I had layed the linkage over to the side, don't think I bent
anything-but the speed control actuator does feel limp wristed-that is no
tension. I double checked linkage-seems correct-the rod to the injector pump has about 3/4 to 1 inch of travel-is that normal? Don't know how I could have
changed that. Could the supply pump coincidentally failed? All hoses in right
