By the time you get enough stuff removed to get access to the front seal you are only about 6 bolts away from pulling the engine. I go ahead and put it on an engine stand to make it easier to work on. I've found things that made me glad I got a good look in there.

The front seal actually seals to the crank pulley, so when the crank pulley is removed there is a little gap. I don't think that gap is wide enough to get the old seal out and new seal in without at least removing the timing cover. A sneaky-pete tool might pull the seal outta the oil pan groove but I usually end up gradually destroying the old seal rather than getting one nice big piece pulled out.

With the engine on a stand I can be sure the job is done right. I can pull the pan, check the oil pump tube, and replace the rear seal.

I prefer to use a one-piece seal on the front if I'm using a new crank pulley. Some of the one piece seals come with a renew sleeve. If my crank pulley is bad enough to need one of those sleeves I'm just going to use a rope seal that will conform to whatever grooves it has.
