Can anyone help me with changing my glow plugs. I have a '92 300D 124 602 engine. I can barely see them much less get in there and change them. My old '83 300D was a piece of cake....but this???? Are there any tricks or tips? What needs to be removed? Can a backyard mechanic do this or am I getting myself into trouble? Any help would be greatly appreciated.

Thanks, dtimmester
