Re: Replacing front crank oil seal on LT1
I'd replace the seal for the water pump drive as well while you are at it: http://www.impalaclub.com/naisso/for...TOPIC_ID=30984
In fact, it may be leaking from there or the opti drive as well and dripping down the front of the timing cover, giving you the impression the bottom seal (crank) is the leaker.
These links below are for a Camaro, but the procedure is basically the same for balancer & hub removal. The hub is tricky, I've done it a bunch of times and it never seems to go completely smooth. You need a puller tool along with varying lengths of bolts that the puller will "push" against after the crank snout bolt is removed. The bolts need to be slightly smaller in diameter than the crank bolt so that they do not thread in, yet still thick enough so they are tough and do not bend when the puller "pushes" against them. http://shbox.com/ci/cam_removal.html http://shbox.com/ci/cam_install.html
