Hi all, my GL450CDi is leaking oil on the right side of the engine just above the lower turbo. I it’s been over 2 years now since I have done the oil cooler seals on this car and then the oil was coming out between the bell housing and the engine. But this time the engine oil looking form under the car it’s above the turbo. I took all the top engine cover off to see if somehow at the top but Bo I could see anything obvious from the top is got to be at the bottom but somewhere above the turbo. Anyone had this before or have an idea of what/where the oil will most commonly come from? Need to find this leak! Any help will Will appreciated. Thanks
