[illness]

i'm planning on removing my engine soon so i can replace the oil pan.

i'm looking for suggestions like,

"while you have the engine out you better change the __________"

OR

"its easier to do _________ while the engine is out"

so far i'm replacing:

oil pan

rear main seal

exhaust manifolds gaskets (the bolts are rusted bad so if figured i'll beat them before they beat me)

thanks in advance for the help.
