Always looking to cut weight anyway I safely can. Getting order together for aluminum bolts for car. Places like 4 x 3/8 bolts for hat,14 or so for transmission pan and others. Wondering how much TQ is needed to keep valve body sealed up? Lots of bolts there and while not a lot of weight its weight I can shave off car, e ven replacing every other one would help. So how much TQ needed on bolts. This is just valve body not valve body to case bolts.
