water pump shaft oil seal

Can you just get that seal or do you have to buy the timing cover gasket set? And I would like to hear your method for installing it so it don't leak. thanks.

I'm sure you can buy just that seal from a dealer. I'm not sure about aftermarket options.

We tried lots of things to get that seal on. We eventually slid it onto an oiled, deep well socket that was about the same size as the shaft. We slid it from the socket onto the shaft, and tapped it into the cover using a larger deep well socket. It worked pretty well for us. I think a lot of people use a magic marker as opposed to a socket. A search will probably turn up some install tips.

Does the timing chain cover have to come off to replace the seal?

It doesn't have to come off, at least not on my '94.

I use the coupler that turns the water pump. I put a slight taper on one end, lube it up and use it to install the seal. Some guys have also used the cap off of a sharpy marker. Either way, be careful cause its super easy to screw up.

AFAIK, auto parts stores don't stock just the WP seal. I had to buy another one from the dealer the first time I ripped it.

I used the exact sharpie pictured here, and it worked PERFECT. A little oil on the seal and it slips right on. Then just tap it on with a socket.

I cut the end off a funnel . Slid right on there . I think it was easier with the T/C cover already bolted on .

I just recently replaced my opti and used the sharpie trick on the seal and had great results. LF

I recently used a combo of the sharpie and water pump drive coupler. The sharpie is nice since it is tapered a bit which allows a nice gradual stretch. Then I transfered it on the coupler, which I sanded a slight taper onto. The coupler is so nice because you can install it onto the drive so it is perfectly flush and slides right on. Just be sure you see it start and end correctly with the back lips of the seal staying back and the front pointing forward.

Another thing that I noticed from a leaky seal which I though I installed perfect was some extra slop in the drive shaft. With my most recent seal their was still a bit of wobble but it was much more snug. This time no leaks either.
