Moinsen, today the elk was supposed to get its new oil trap. So it was done and everything was dismantled and then the shock: Both holes in the engine block were completely dense with oil charcoal. I carefully tried to pour out the stuff. When the holes were so far free, I took out more stuff with a wire. I found out that the holes are open at the right angle and there is also oil coal in it. I am sure that parts have also migrated into the engine. So the elk. Tomorrow is going to a self-help workshop. My plan is to dismantle the oil tank and clean everything. My question is: Does anyone know how the nodding channels of the drilling continue? Is it going directly into the oil tank? In another Volvo_Forum I have just read that the channels do not lead into the oil tank. But how do you want to clean them and where do the channels go??? Who can bring light into the dark? Oh, yes… is it right that the oil bath “only” is sealed with means?
