Hello Elche^^ I have an urgent request and hope that someone can help me here… So this is the following: I drove 500km with my Volvo on vacation the day before yesterday… and when I was driving down from the highway, my oil control lamp comes in. So I stopped, look what’s going on… engine absolutely dry. So fill up oil… and look there: 4l was missing!! So the bucket swallowed 4l/500km… then I hit the engine again and heard that the engine is horribly clapping… I thought spontaneously about the hydro impact… and the next day in the workshop the master also thinks: Hydro impact and probably also valve shaft seals broken… I would like to exchange these now, because the repair in the workshop probably costs a fortune… and in this way I ask if someone can give me tips about it. Specifically: – How big is the effort? – Are special tools needed? – What do you have to pay attention to? – Does the repair at all cost? My Elch now has 238 even got to give me some advice – if I’ve got some advice?
