OM 602 question for the experts...

I'm new to the diesel world.....I have a '91 300d w/ 74k and was wondering does this car need valves adjusted like on the 617.

while driving I noticed that driving about 15-25mph and taking foot off pedal then barely pushing on pedal that notice some clicking.
is this normal?

No, your car has hydraulic lifters. The lifters could be the clicking, but you should be able to hear them at idle.

No and probably yes

A DEEP-SKIRTED CAST-IRON BLOCK, a high-volume oil pump, forged steel connecting rods, a spin-forged crankshaft, and a valve train free of pushrods and rocker arms all help the Diesel engine achieve bulldog toughness.


1.) Double-roller timing chain
2.) Direct acting overhead cam
3.) Precombustion chambers
4.) Forged steel connecting rods
5.) Spin forged steel crankshaft

But I'm no "expert"
