Rear main seal.

Have a pretty bad rear main leak when it runs I go threw a quart every 100 miles. It doesn't leak when I stop because of the leak stop I put in but when it runs I always have oil all over the skid plate.

My question is can I change the rear main seal without pulling the engine. I read in the service manual that the old seal you had to have the crank out to replace, I know the new seal I can put in without pulling the crank out but the old seal is there a way of getting it out without pulling the crank as far as I know this block has never been rebuilt.
I would need this seal to last just through the winter I plan to rebuild it in the summer.

 

Which engine?

Yes, you can change the rear main seal with the engine in the car. If you have an F134 and use the rope seal, you'll need a seal puller, often called a "sneaky pete." http://www.amazon.com/Lisle-27000-Sneaky-Pete-Tool/dp/B0002SRCJW

 

My bad yes an f-134, I guess in my mind that is the only engine in jeeps.

Thanks for the link any preference on what type of seal to use I heard if the rope isn't asbestos it is not worth it and just use neoprene.

 

If you can find a neoprene seal, they are better. Sourcing one for a F134 has gotten difficult, according to earlier posts. Apparently Felpro only offers the rope seal now.

You could try Walck's for the rubber seal. Search - this has been discussed before.

 

Found them here:http://www.kaiserwillys.com/product/720/willys-jeep-engine-gasket-sets-oil-seals-parts-accessories Make sure you get the rubber dowels in whatever kit you get, and don't forget a new pan gasket. DON"T CUT THE DOWELS SHORTER. They need to compress and fill the cavity they go into.

 

Thanks, Anyone have any experience with these seals?

 

This seal or rear main seals in general?

I've done a few of them in other cars.

 

I meant the seal from kaisers just curious who makes it, and if it is any good.
