85 300TD A/C belt keeps coming loose.
I'm having an issue with my A/C compressor belt on my 85 300td. It keeps coming loose.
When I bought the car 2 months ago, the belt was missing completely and I was not sure if the A/C worked or not. I installed a new conti belt. The a/c works perfectly except after 200 miles or so the belt comes loose. Yesterday I checked the belt and now it looks slightly chewed up on one side.
I'm not sure if the problem is A/C pulley or something else.

1982 300DT vacuum troubleshooting
I recently purchased the Vacuum Troubleshooting kit and have begun to tackle some minor issues with my wagon.
Right off the bat I find something not specified in your manual.
I started with a vacuum pump test and my gauge is reading 16.5 inHG. When I remove the line from the booster it reads 19 inHG - neither seems REALLY low, but are below the 20-23 inch range.
I have two questions:
1. Is there a way to determine if my checkvalve is leaking versus a slow leak in the pump itself?

79 W123 300D- compression check w/o radiator in place?
Have a blown radiator which I pulled- How do I do an engine compression check to rule out cracked head or blown head gasket w/o the rad in place? Doesn't make sense to reinstall the radiator (-it's blown) or install a new rad just to test. Any ideas will be welcome as none of the mechanics down here seem to have any clue...

83 300D Turbodiesel - Strong vibration under load
I recently purchased this 83, 123 chassis Turbodiesel about 3 months ago. It has 160K miles and has been very well maintained. I recently replaced the injectors, glow plugs, adjusted the valves twice, with three weeks between adjustments, and the compression currently checks out at 340,380,380,380,380. I got quite a bit of benefit from doing a diesel purge, banjo cleanout, and ALDA adjustment. All of my efforts are aimed at bringing this car as close to optimal operations as possible.

79 W123 300D-Blown Radiator?
Driving down the interstate on my way to a gig (I'm a musician)- First noted the BATT light come on-Which I assumed correctly to be a shot belt- but also noted the engine was overheating.This is a new (3yrs old) OEM BEHR radiator I installed) Pulled over-antifreeze all over, radiator cap intact,but the top of the radiator was tilted about 20 degrees from horizontal, tilting up at the engine side, exposing the rubber tubular gasket around the top, and the metal mesh underneath. Obviously bent up somehow and in doing so disconnected the plastic housing.

82 300TD Engine Heater
Making my question simpler. I am removing the engine plug to install the block heater. I am using a 19mm 1/2 inch drive Allen an extension and a 20 inch breaker bar. I have put some torque on it and it does not budge. I do not want to break anything. How much torque is safe? Any suggestions?
Thank you
