Hello guys, since my treasure is standing in the car gas conversion the suction tube has to be built in the middle. It’s a 2.6 V6 Now I found an explosion drawing in the clever book (see appendix) According to that the head screws have to be pulled after the suction tube expansion. The rebuilder thinks this is Quark and also I don’t understand the connection. Can someone tell me if you really want to do this or not ?
