Ok wtf is the trick to getting these damn dipsticks installed into the block... just broke a third one :BangHead::BangHead::BangHead::BangHead::BangHead:
Put an box wrench over the tube to the flange. So it will not go past. Then get a length of pipe over the tube and tap it in with a hammer. Will be pushing on the flange, the box wrench, not the top....
