It's correct that the o-rings and copper washers are the same as those for the OM603 such as the 87 300D. I don't know why these parts are not being carried for the OM606.

I didn't know that one is supposed to replace the compression springs when doing this job. I don't even see these in the catalog. I also don't know why but after each time I did this job I got more nailing at idle, but it should subside eventually. It took my '96 about a month after this job to get rid of the idle knock when warm; there's still some when the engine is cold but it was there before the job too. Also I don't see any need for taking out the pressure valve and carrier while doing this job, only what's above these parts.
