LT1 Water Pump Drive Seal Replacement
I need to know the best way to install the seal in the timing cover for the WP drive shaft. I have destroyed 3 seals during the install.
The seal appears to actually have two seals; a front (tan) and a back (black). I think I need to fold the rear seal towards the front and then try to slide it over the drive shaft but I am concerned about it leaking. I thought I might need to pull the timing cover, install the seal and then put the cover back over the shaft but the result would be the same, the seal has to alide over the shaft. My Haynes does not discuss this issue so I am looking for help!

Just finished putting the front of my engine back together today to get rid of the oil leaks...DONE!!! I have MUCh experience with this seal (done it 4 times now). It's definately easier to get the seal in if the cover is off. However, you will have to lower the oil pan to get the timing cover off and then on again. If you have an LTI (don't know about the others)...this requires removing the Oil Filter Bracket as well (one of the oil pan bolts is above it).It takes 2 people to put it on while still on the car. I held a socket over the seal (obviously same diameter) and had my buddy tap (more like bang) it on. All in all...it's definately less work to do it while still on the car. It's a tight little mother and always wants to **** to one side. As for the 2 seals...they will have to be pushed forward to get it onto the shaft...there is absolutely NO way you can have the black seal facing backwards toward the gear. There's a possibility it will leak again...I've had more than my share of crappy seals that I've put on. Hope this helps.

Now I need to figure out the routing of 2 vacuum hoses but that will be a different post.

The key to installing it is the oil use it everywhere the seal will touch.
