Rear Seal

[Diseazd]

Anyone else feel like the Nissan rear seals aren't up to snuff? My 73 just developed a pretty good rear seal leak. It has a new (blue) Nissan rear seal (2000 miles). Which seal works best for you? I'm going to go back with Felpro. I was going to replace the tranny with a 5 speed anyway, but it still makes no sense why a seal with that low mileage would start to leak. BTW, it isn't the groove that's the problem....I always allow for that.

I've been fighting the rear main leaking from almost day one.

Still leaking;(

Did you use a Nissan seal? I'm going back with Felpro......It's such a PITA to replace too!

I think I've used both and I also have a speedi sleeve installed. New side seals, oil pan gasket , etc...

I suggest buy some Nissan silicon and not the permatex stuff.. I could see and feel the difference between the two.

I'm referring to the crank seal.... Not the side seals.

Sorry to hear this, it is a royal pain. I'de be very suspicious of the crank surface. A speedy seal is a good thing as Steve indicates. No reason for that seal to leak unless something is chewing it up.

Just finished the tranny swap......while I was at it, I pulled the clutch and flywheel. The seal was dry, but I replaced it anyway. When I was finishing everything up, I noticed a drip of oil coming from the bottom of the heater hose. I lowered the car and discovered a pinched gasket at the rear of the valve cover........wasn't the seal after all.

Right you are Blue......that's how you get smart....by doing stupid things! At least I was going to swap the tranny anyway. :stupid:
