Going to look at a 300D tomorrow. I've wanted a Mercedes for 10 years now, but high school and now college seem to have gotten in the way! The price is right on this one, so I've got to at least look at it!
Anyway, the car has 182,000 miles. I know all about MB diesel longevity from reading the posts here, and looking at the mileage on the cars in the classifieds, but I still think it would be a good idea to check the compression. HOW do you do this on a diesel? Through the Glow Plugs?? In the forum everyone always says: "Check the compression", but no one ever says how... Obviously a guage, but where do you find one that goes up to 300+psi? These 3.0 5cyls. should develope 320psi with a variation of no more than 25psi, correct? I am mechanically inclined, I just don't know how to do it on a diesel and cannot find any info regarding the procedure, particulary on a MB Turbodiesel.
What is the best way to check the turbo when I look at the car?
Also, what are the typical "soft spots" of a 123? Where do I need to look to aviod getting a hidden rust bucket? I don't mind changing out parts, but when th body is gone, there is no going back.
Any other thoughts before I look at her would be greatly appreciated.
Thank you!
