John,
Welcome!
Regarding the
oil leak, make sure that it isn't something like a loose bolt at the rear of the valve that allows
oil to drip along the engine and eventually drop from the tranny/ engine area appearing to come from the rear main seal. I was sure that I had a rear man seal leak once, but after putting dye in the
oil and inspecting things, I went "DUH!" and then "Thank you, Lord!".
Hopefully you will be as lucky as I was.
Cheers!
Dave
