I have a bran new seal that's already installed in a new metal casing. I also have a new timing cover but they don't seem to agree with each other. I've sanded the paint off the seal casing, sanded the timing cover surface, tryed oiling and lubing, doesn't seem to want to go in square. I've been setting it on the work bench and using a block of wood and a hammer. Is there any better method. Has anybody else had this problem? Thanks guys.
