Proper compression for 92 300D?

Hello everyone,
just wondered what proper compression is for a diesel. I have a 92 300D, and my shop recently did a cold compression test with the following numbers- #1-340, #2-330, #3-290, #4-320, #5-320.
He said that these were pretty good for a car w/ 270k- I just wondered what anyone else thought. The car seems to start fine, and runs well.
Thanks!

1982 300SD wipers problem-

I have a 1982 300Sd that I am repairing for my kids to drive. I can hear the wiper motor running but the arms do not move? I know I have read somewhere about a Bakelite piece or something that wears out and it controls the arm movement. IS there a simple modification repair that can be done...AND how do I get to it, and how do I make the repairs.

1984 300D Decrease in mileage

My Benz "Old Yella" had recently slipped a little in the miles per gallon dept. I have developed an obsession with the car and stay right on top of things mechanically so I was a little puzzled. The air filter was coming up on my periodic maintainence schedule so I decided on trying out a K+N. I usually change air filters after about 20,000 miles of use. This figure is flexible as all driving conditions are not the same. Dust, road salt and sand can all gather in the filter and constrict air flow which is essential to internal combustion engines.
