OM602 Diesel Oil Stem O-Rings & Viton O-Rings for Biodiesel

[ArmchairExpert]

For my OM602, 2.5 Turbo I bought a lifetime supply of the Oil Filter Stem O-Rings, Fuel Filter O-Rings, and enough Delivery Valve Seals for 4 or 5 engines.
If you have an oil leak at the IP Fuel Shutoff Lever the O-Ring is either the same 2 x 6 MM ID or 2 x8, can't remember offhand. They also have BunaN and Nitrile for slightly less.

Owners of other model engines can check their measurements and if different, use the lookup on McMaster-Carr.
