Short of buying the expensive tool(s) listed in the FSM, anyone have any tips for removing/installing the timing cover seal on big blocks?

Put it in place and find an old small block piston or a piece of aluminum that is slightly bigger than the seal--get it all level on the bench and one whack it will go in fine--maybe two if you are timid--just try and get it started square--You can put another piece on the piston to have a good place to whack---double check the little tensioner spring around the seal to make sure you did not knock it off--if so pop it right back on and keep rolling

Quote:drill 2 small holes the dia of your smallest pin punch (maybe 1/8") in the front of the cover opposite each other maybe at 12 and 6 o'clock around the flat perimeter & drive the seal out the back side evenly. When you drive in the new seal it will cover the holes back up. As said find a round flat plate of scrap metal or hard wood slightly larger OD than the seal & set the cover on something flat/stable & LEVEL/SUPPORT it & get the seal barely started SQUARE w an easy tap or 2 then drive it home w a BFH & something for an extension like a 1" dia 8" drift w as few strokes as possible as each stroke increases the odds you will either tilt it and or distort the thin perimeter edge as the flat face side of the seal goes in the recess 1st & you tap the open face
anyone have any tips for removing

This is not possible since the steel shell of the seal is inside the cover, what would you push on ?

No there are a number of ways to remove the seal , but doing it in a press isn't one of them unless you are also trying to destroy the cover.
