Hello! A question to the people who have the smart WIS program. If I want to change the cylinder head gasket, I have to reckon with which hourly approach in the workshop? My estimate is from 4 hours but I can also deceive myself. The change itself belongs only to the seal (without sealing mass or with sealing mass?) and 10 stretching screws! That’s right, right? The parts themselves amount to 77,80€, but now is the question of working hours. Must or should you let other parts change immediately? Ask only because often the workshops want to do even more x- other things. But I think only to let the seal change if it is necessary!
