i just bought a 89 supra turbo, and my cousin was driving it home from the old owner and noticed that the oil pressure was low. he pulled into a toyota dealership in kentucky and they told him that the crank seal was leaking. he put oil in it and the pressure was fine,but i'm wondering how much is this going to cost me and how hard is it to fix. thanks.

Assuming that you're talking about the rear seal: pull the tranny, remove the seal (or you can remove the seal carrier first), put a light film of oil on the new seal & lightly tap it into place using a block of wood to distribute the pressure from the hammer.
The "crank seal" is in front. The "main seal" is in the rear. As the poster above indicated, were they talking front or rear?
The front is even easier.
Pull the radiator and hoses, fan, front main pulley, timing belt covers, and then the timing belt pulley off the end of the crank. Peel out the old seal, put in the new one in the same manner as described above for the rear, bolt it all together (perferably with a new timing belt, can't hurt!) and you are good to go.

thanks for your answers guys, but the news is worse. my mechanic looked at it and said that the rings are messed up. so looks like i'll be replacing cam seals,crank seals, timing belt, and head gasket all at once. any suggestions on what to do while i've got it tore down. i can get the heads resurfaced, but the block is stilll going to be in the car.
would it be smart to go ahead and replace oil pump since the oil pressure was low, or would the bad rings make the oil pressure low? sorry for the dumb sounding questions, but i am a construction worker and not a mechanic. thanks again for the help.
ALso... it would be smart to replace the oil pump if you pull the block. It can't hurt, and it might help in a big way.

no
to replace rings requires access to the bottom end WHCH requires lifting the motor to remove the cross member which still needs the bottom end removed to mic the crank and stuff. Engine has to come out.
It sounds to me like you will be dropping a bunch of money on somebody that really doesnt know what they are doing.
