  To replace the rear main seal you have to either remove the engine or remove the tranny as the seal is a solid piece. The book says you need a spiecal tool to do the job but just drill a hole or two in the seal,put in a screw and pull out carefully.
  Good luck

I had the engine out, drilled small hole, put in a sheet metal screw, and popped it out with a small slide hammer. The new seal went in easy.
Thanks for ur advice.

  Allright, I'm glad it went well for you. No more oil soaked cement :laugh:

If you're willing to give it a shot first, there's a product being sold by a company called NuTECH, that is guaranteed to stop oil leakage from a deteriorated rubber seal. they run ads in Popular Mechanics, and some other magazines.  If the price hasn't gone up, it's about $15.00 for enough to treat an oil system of much more capacity than the Pinto engines hold. Even if it just slows the leak down significantly, that may be enough for some people.

On a related note, anyone replacing the rear main seal is shooting themselves in the foot if they don't check the main bearings for wear, and relpace them if worn, as wear there will enable the crank to move around enough to make a new seal fail much faster than the original one, possibly even shortly after installation if there is a lot of bearing wear.

I've used it with some success. As long as the seal lip isn't actually chewed up and has chunks missing, it seems to work fairly well. It's supposed to work equally well in transmissions, rear ends, power steering, etc. as well as engine oil. I've used it in power steering with mixed success. I also used it directly on EXTERIOR rubber parts, such as window glass moldings, and it seems to help them regain some elasticity.
