I pulled the intake on my OM603 today to replace the leaking gasket. (previous owner replaced the glow plugs without doing the gasket --> leak) Everything went fine and I've bought new bolts, as the old bolts were starting to get worn.

But now I see that access to the whole left side of the engine, like injection pump etc. is really good. Is there anything down there around the injection pump that I should check/replace while I have the intake off and such good room to perform any work?

Depending on how old the glow plugs are............and how skillled a mechanic you are............changing them now might not be a bad idea.

Changing them without the manifold in place is 10 minutes...........changing them with the manifold in place is where the skill (and tools) are required.

You might consider cleaning and lubing the "throttle" linkage. ATF seems to be the lubricant of choice.

The glow plugs were done a few months ago, just before I bought it - I haven't owned the car more than a few months.. But thanks for the tip!
