My question for you guys that have already done it is, is the oil cooler really bad Leaking from the cross over tube from oil filter housing to the block.
Notice the oil filter housing was replaced. Suspect that the crossover oring is leaking. Recommend taking back to the shop that replaced the oil filter housing. once again, back to the shop that covers oil cooler under warranty for a 3rd time! The turbo oil input line is above all of that, and either leaks at the top of the center of the turbo (its under the heat shield), or at the oil cooler

It’s way higher than i was expecting, and there are other parts such as a tensioner and belt that i don’t feel like are any part of the replacement of the oil cooler.
Hello experts:) i`m owner of a ml350 bt from year 2013, 115000km on clock. I had noticed a litle oil leak from rear of engine over time (6 mounts). I took the car to workshop. They said the oilcooler seals was leaking.
