The factory MB turbo drain setup is a joke. Almost impossible to get at the flange on the turbo, who in their right mind would install an o-ring seal slip-fit in the upside down position, is asking for a leak. The lower tube is impossible to pull free without liberal cutting of the lower seal with a utility knife..... The whole setup sucks. I changed all the seals when I had the thing apart for a headgasket but doing it just for the turbo drain is silly IMHO. RT
