81 240D 3 Water Pumps In 6 Months

Hi--- I have an '81 240D fitted with the 2-tank Greasecar system. Don't do too much of my own work, but I'm using the 75 MPH Guide to keep Anna happy and healthy. So far, so good... but, I've gone through 3 water pumps in less than 10,000 miles. The 1st was the original, so I new that would happen. And it did at exactly 120,000. Had it replaced with a Bosch, which promptly failed. Had it replaced again with a German pump, the name eludes me. Well, this pump also failed and I'm having it replaced with a Mercedes pump. Fortunately, this is all warranty work.

82 300D has slight miss on one cylinder

82 300D has slight miss. This engine has 157,000 miles on it and runs good at highway speed. I can losen the fitting on each injector and make it run like a gas engine when you pull a plug wire. Has only slight miss when all injectors are tight. There is definitly a lose in power at low speed taking off from a light etc. The injectors have been pop tested and all are good. Compression test shows around 325 to 350 psi on all cylinders. I have adjusted the valves twice to make sure one was not to tight.

Diesel Engine Specific Aid

Okay, so I bought a 1983 300D Turbodiesel. And now:

Hi all. New member as of today, and today I also picked up my 2nd Benz. I have some experience with my 1971 280S, but today, I bought my first diesel. The cars rather amazing overall, for a black on black leather car with original paint. One owner. 200K miles. A few little problems that I already see answers and/or parts for. Here's my concern. The car is amazingly slow from a stop to 10 or 20 MPH. Then it's decent, much like a gas car. I see an unusual "part", seemingly disconnected in the engine compartment. It's like a little frame with heavy coils inside of it. What is that part??? It seems to perform much better once it's warmed. I know NOTHING of it's history aside from a clean VIN check, one owner, 400 miles in the last 2 years and it was probably garaged.

84 300TD Wagon won't start parked on a hill

My '84 300TD Wagon won't start if parked facing uphill - even the SMALLEST of inclines actually. Doesn't seem to have a probably parked facing downhill. Because bleeding the injectors gets it to start, I'm assuming it's air "in the system". Is there something I can do about this or is it just because the car is old? Thanks.
