Do any rear main sealers work?
Hello all,
For a couple of years now, I've had a very small, very slow rear main seal leak - not enough to cause me to have to add any oil in between changes, but enough leave very small puddles if the car sits for a few days. I know there are a variety of products out there that claim to be able to "fix" these, just wondering if any are worth the effort or money? Until it gets worse, I have no plans on replacing the seal.

Band-aid temporary fixes until you get the job repaired properly.

Searching for the same thing and came across this topic. Does the Transmission have to come out or take the engine out to get at the rear main seal on the 350 Engines?

My Buddy's hoist is all booked up in his shop so its either leak with my minor leak or put the car on jack stands in my garage and pull the transmission!

There are no miracles in a can. I have actually tried a few. Lol. None worked.
