Rear Main Seal leak on my 72 dodge dart

Just confirm that it's the rear main. Check real good for rr. intake seal, valve covers, even distributor flange. R & R the main seal is the last thing you want to do if you don't have to. And no...trans. can stay. Phista's tool may really help if you have to go there. Good luck, Rick

P.S. i assumed it was a V8 since you posted here.

And welcome to the site:)
