Just a small quick question I couldn't find the answer to, where is the Oil seal and how much will it cost to replace a new one?

 

It's inside the engine.
Check out prices for "rebuild".
I'd say we're talking $1,000 EASY done by a "professional".

Go to the Factory Service Manual and read the ENGINE section. The engine section disassembles the engine and then reassembles it. You can see graphics of the seals in that section.
