      and now for my 2nd question the day…..
      Before I remove the engine (Strut Replacement), I want to do a compression test. I need to purchase a tester worthy of the task. I believe I need to remove the heaters to do the test. So I am thinking I will need an “adapter” to Thread/ Insert into the head where the heaters were. Anyone know anything about this? This is for the W58.

      Generally speaking, you use a compression tester in the injector holes – I’m
      not sure there’s an adapter for the pre-heater holes, but a diesel mechanic
      would know better.

      Alan-
      It certainly would be easier to use the screw in glow plug hole rather than the fuel injector. Diesel compression testers usually come as a set with adaptors to fit common engines. Perhaps you could remove one glow plug then match it up to an adaptor at someplace where they have diesel engine compression testers.
      Two cautions:
      Pull all the glow plugs out before you spin the starter. If the engine starts, it will ruin your day.
      Be sure that the adaptor does not extend further into the engine than the glow plug does.

      There are special purpose adapters made for compression testing a diesel.
      You’ll use it so rarely that its hardly worth the investment. I used a
      different tool for my compression test, a checkbook. I hired a mechanic to
      do it for me.
