Default Front oil seal question

Front oil seal is leaking on my 93' vert LT1. I've done a lot of work on chevy 350 engines. Will this job be difficult? Thanks for any comments.

Pretty straight-forward, but it is space confined.

Gotta remove the waterpump, opti, balancer, and the hub. Pry the old seal out with a screwdriver. Clean up any debris. Put a Very light coat of RTV around the outer edges of the new seal (serves as a lubricant during the install), and tap the seal in place.

For a seal installer, I use a short piece of PVC with one end capped. The open end slips over the crank snout and fits the OD of the seal while the capped end give you something to tap against.

Man you are already there, just remove the timing cover and install it on the bench. It's just one more gasket to buy in the big picture. That's the way I have always done it. Now you won't be space limited.

Don't forget to drop the oil pan before removing the front cover, as the front cover fits into the oil pan gasket. If you don't drop the pan, you will likely tear the oil pan gasket trying to remove the front timing cover. If you go that far, might as well pull out the stock cam and install a hot cam...
