I am almost positive that my 97 LT1 had an o ring on the shaft for the water pump but you guys are probably right .

You are right, there are two o-rings on the wp assembly. But it holds no oil, just keeps dirt out of the hard grease.

seal on WP = 92-95 LT1 - 12553792 96-97 LT1 - 10128329
seal on drive = 92-95 LT1 - 12553792 96-97 LT1 - 12553792

The o-rings on the water pump shafts are to seal the grease in the coupler.

Perhaps your shaft was wobbling and the o-rings helped stabilize it. I would have changed the timing cover seal while I had it apart.

A dab of axle grease should work on the shaft ends. You don't want the coupler and gears to eat each other up.

Axle grease or bearing grease would work best. Anything thats a hard grease that won't liquify and leak out. Hard grease will melt but its usually close to 450 degrees.

How do you change the water pump drive seal without taking off the OPTI and everything else? Can it not be done? because it looks like the top of the OPTI is in the way by only an 1/8th of an inch to have it just slide off and on..
