The last rear main I replaced on a 6.2 was the rope style. I'm told there is a new replacement for this type of seal that is a lot more reliable. Does anyone know about this seal and the replacement process?

When I did mine I just went to the parts store and got whatever they gave me. It was rubber and had good instructions on how to install it. The biggest things to watch out for installing it is to make sure the lip is pointed in the right direction and if you are not taking the crank out, when you slide the new seal into the journal you have to have something to keep it from getting damaged by the sharp edge of the block. I used a little sliver of soda bottle plastic and lubed it up with motor oil then slid that bitch in. Actually putting the new seal in takes like 10 minutes, if that. Its getting to it that takes so damn long...

Yes, there is a new seal and once you get to the rear main it is fairly easy to replace.
But as has been said, it's a bee-atch to get to
Many reccommend unless yours is leaking a lot don't.
Make sure it is the rear main as well. Leaking oil cooler lines will often look like the rear main leak.

Weirdest thing happened. The rear main was pouring like someone was sitting on the engine with an open can of oil. I was able to get a pan under it since I was watching for a rear main leak. I let it sit over night and cleaned the pan and torque convertor cover up the next morning. I started it up to move to a spot so I could pull the pan. When I checked there was no leak, so I decided to run it for a few days before going through the pain of changing the seal. The thing hasn't leaked since that first time!
I have never had a seal fix itself. I've seen them leak a little less, but this thing is bone dry. I guess I'll just watch it for a while and see what happens.

Did you check the oil in the motor?

I guess that would be a sure way to stop the leak. Expensive, but there would be no leak

I'd replace it anyway.
So after a leak like that you are going to trust it won't do that on the highway and leave ya stranded?
So, are ya feeling lucky Punk? Well ARE YA?
