Found oil leak, what do I do now?

Im almost positive oil leak is coming from rear main seal. It is seaping out of the bottom of transmission where it meets the back and bottom of oil pan. Isnt that where the rear main seal is? If I am right, after I buy a new seal, what do I do then? Is this a pain in the butt to fix? Thanks, I dont know what I am doing.....

Never seen a 258 that didn't seep. Just marking it's territory.

Mine did too. I just happened to have a motor that doesn't leak and now am in the process of finishing the swap. It doesn't help much that it is COLD here. It is one of those things where you have to weigh, amount of work to fix and how much does it bother you. I know I will get the opportunity to fix the motor that I pulled but until it warms up I haven't done it yet. Anyway good luck.

Before attacking a rear main, I highly recommend you run the engine for a few minutes to warm it up and then take a clean rag and rub the engine head around the back side below the valve cover. If you find oil there, you have found the leak likely, well 'a' 'valve cover' leak that for sure imitates a rear main seal leak perfectly.

Oh yes, and the engine tilts back so it runs right down to the bottom.

if you find it is your rms leaking, here's an excellent step-by-step with pics write-up on how to do it. it's not an overly difficult job, but it is a pita. pretty messy and time consuming but doable if you're somewhat mechanically inclined.

Did mine a few months back. As you will see when you read the step by step instructions will have to remove a motor mount. Even with the motor mount out is was still a little tricky getting it in to place without knocking a gasket loose. Having a extra set of hands around really made getting the oil pan back in to place easier.
