I need the number of a modern crankshaft seal that I can purchase at a local parts supplier, so I will need an Auto Zone, oriellys number please.

From an older post, this may help.

Here are 3 different seals that will work at the front crank:

1. A C/R #12458
This is the thinest one

2. Chaffin has #3012M which has a very nice design but slightly thicker for 7 or $8.
A NAK #TB-H 1.187 1.828 0.375

3. A National 3438R
This one is a heavier and wider seal.

The method I had to use was to cut and fan outer flat of the seal and install it facing the wrong way because of the clearance issue. This sort of made it look like a daisy but also gave it a lot of surface for the JB weld to grip. I never had a leak there again. You can barely see it and I liked that. The neopreme seals have a spring that applies some slight tension against the surface which provides some longevity to the seal.

The great thing about the seal on the outer surface is that in case you have to remove the front cover it is not locked in place by the crank and oil pan!

John, Let me know if you aren't able to find a seal. Also don't use the JB weld but instead pick up a tube of Permatex ULTRA BLACK gasket adhesive/maker.
Once you use some of that you'll find more uses for it than a Flex Seal commercial on TV!

Make sure you clean off all oil and grease first.
