What is your oil pressure at hot idle? If it is 1 bar or greater, you have nothing to worry about --as long as it increases the second you blip the throttle to 1000-1200 RPM. Mercedes actually says in their owners manual that less than 1 bar of oil pressure at hot idle is acceptable. Mine just turned 250K and idles hot at 1.75 bar.

With that out of the way, you might also want to check the rack damper pin in the back of the injector pump. The new redesigned one is gold zinc plated, the old one is silver colored.

Do a search of previous posts about the rack damper; there's lots of information on why it is needed and how to install / adjust it.

It's much easier and cheaper to tackle this than it is to go after the motor mounts, and if you have the old-style silver one, the new one WILL make a difference.
