valve seals???

[newkid17]

ok so my girlfriends 92 is blowing a little bit of blue smoke.... first thing that came to mind was rings....but i was talking to my tech teacher and he said he would check valve seals first..... what do you guys think? and to do valve seals would i have to take the engine out????

my 92 needs valve cover gaskets... would i need to tear the engine out to do that as well?
