Re: blowing crank seals out of case
It is probably just a question of 28 years of wear have loosened yo the mating face a little. If you think of the construction of the crankcase the seal is going to be the weakest spot. When I rebuild my 86 I just tapped the seals in and after 2.5 hours engine time I popped the rear seal. When I replaced them both last summer I used Loctite blue bearing seal and so far all is good.

Re: blowing crank seals out of case
I failed to use locktight the first time I replaced the seals. Guess what I had to do last week.... Seems to be fine now, good advise to follow.
