I have a leak all around my oil pan. My problem is the truck is a 1990 with 103k miles. It had 95k when I bought it in April. I think it just sat too long and dried the seals up.

1) Maybe I should try some stop leak?
2) Replacing the oil pan, should I try lifting the engine up or just take it out?

 

No, man. Just no.

Just remove the nuts on the motor mounts and lift the engine a few inches. Don't replace the whole oil pan, just the gasket (wasn't sure if you mistyped that or genuinely wanted to change the whole pan.)
