I had a seal driver for the tail stock that I used to drive them on. Yes, they are tight and should be. It wouldn't leak with a good fit and an new "O" ring installed. The dipstick might if you are using the old "o" ring style. Do yourself a favor and update to the new style dipstick that uses the top hat style seal on it. They will not leak. The old ones "O" ring style are notorious leakers.
