I have a 96 e300d, and have a leak at the delivery valves. I have the seals, but the one step that I could not find an answer to is the collars that are in the area of the splined nuts. Do they need to come off before the splined nuts, or do they stay in place, and the splined nut simply unscrew? Thanks for any info you can provide.

Involves replacing one o-ring and crush washer per valve and torquing back down. Easiest to R & R intake manifold first but possible to do with it in place (I took mine off). Requires a special splined socket and torque wrench.
Has nothing to do with pump timing.
If you want to do it yourself let us know one of us will walk you through it.
