There are o-rings inside the delivery valve holders.
You need a special splined socket to remove and torque the delivery valve holders. There's also a special torque sequence that's in some MB service book but not the basic 300D shop manual. Sixto 87 300D

I don't think this point was made in that otherwise informative thread -
http://www.peachparts.com/shopforum/showpost.php?p=911422&postcount=11 It's the technical data manual (TDM) that has the torque procedure not found in the factory service manual (FSM). Sixto 87 300D
