You still have not made a case, at least to me, for not seating input shaft seal all the way in to the cavity. Steptoe ought to know and that is what he says that he does. Easy enough to make the pvc seating tool if you want to.
I'm fairly certain that I say an uncovered bearing from the cavity in my 2000 build date. That does not mean that yours is not covered. I don't see what difference that makes anyhow. I do not recall an groove cut in the cavity to oil the bearing such that driving the oil seal in too far would block it.
I'll get some pics this time while I'm in there. I'll even use the snake cam and get in there close if it looks like something.
