well yea, I will admit, i started this thread a LONG time ago and since then, wrecked the Benz. I have been working on the body since then, and now have it in pretty good shape. The engine...well, i never bothered with it, besides removing the extra solenoids for the two battery setup, which has proven to be a very wise idea. The engine came to the point where it wouldn't even turn over, but after removing the whole series/parallel junk, it turns over, and I managed to start it last week.

So I'm at the point where my battery IS good. It is a very good, Energizer brand battery, and has around 700CCA I believe. That is sufficient for starting this Benz in my experience.

So when I am cranking this engine over, it seems like there is something that is "resisting" the starter. It seems like the starter is having to strain to turn over the engine. After awhile though, it will turn over the engine like any other car that is in good cranking condition.

Another thing I'd like to add is that I have all new glowplugs, and I've checked them, they are working. Also, I've checked the relay, all pins on the relay are receiving battery voltage, but I have yet to check the current of the plug that goes to the glowplugs. From my understanding it should be about .1 ohm for each glowplug. PLEASE correct me if I am wrong, because that is just what I read on another website. Also, I have a heat gun (with the little laser light that tells the temp of the thing the light is on) and each glow plug seems to be at at least 15-20 degrees higher than it was if it were cold (around 50 degrees F).

The constant fluctuation in the starter is what is really bothering me. Would something like VALVE ADJUSTMENT have anything to do with making the engine harder to turn over by the starter? Meaning adding more resistance to the whole starting process??? I would truly love to adjust the valves, but if I don't have to, then I'm not going to.

So I guess my main question is, would valve position change, overtime, increase the load on the starter??

ALSO!! Another thing. When I push the gas pedal while turning over the engine, the engine IMMEDIATELY goes into "slow crank" mode and barely wants to turn over. This HAS to mean something to somebody!!!

When I PRESS THE FUEL PEDAL WHILE STARTING, the engine IMMEDIATELY goes from turning over decently to turning over VERY SLOWLY. So slow, that there is no chance that it could even start.

Once again, thanks EVERYBODY for the help. I've gone through ALL the basics though. Glowplugs, battery, checked for fuel delivery, checked vacuum, and almost anything else "basic."

Help once again would be appreciated!! Surely these facts I've listed will bring something to mind to those that are diesel/Benz experienced!!

I'm so thankful for a forum like this...its so handy for the DIY'er!!

also, I don't think I need another starter...but if anyone thinks that the symptoms presented are due to the starter, then I am willing to get another one. They just cost an arm and a member.
