Earlier Sprinter vans have been running WVO for years as have been VW TDI's, all at 20,000 + PSI. And, yes, the key to longevity is the quality of the fuel and the operator of the system (don't run it cold, completely purge the system before shut down).
Back to the ML...
It has had the turbo seals replaced and the servomotor replaced.
He is not sure if the oil cooler seals have been replaced.
Does anyone know if the failure of the seals is evident by visual inspection ?
What fluid leaks ? Oil, coolant, or both ? Can the failure cause a mixing of the oil into the coolant or the coolant into the oil ?
Thanks,
Greg

Oil only.
1. You can use a borescope to peek at the aft part of the oil cooler. Without a borescope you Can't really see nothing from the top side as all is covered by fuel filter, intake manifold, turbocharger and swirl motor.
2. From the bottom you can look for traces of oil where the block meets the bell housing. Most of oil will be visible coming from the left side but not really traceable to anyplace specific as it is coming from a through hole drain in the vee of the engine block.
Old seals were reddish orange; new seals are purple.
Hope this helps
