Those that follow the Buick RM forum may have seen this already, but for the rest of you:

A debate arose about oiling the lips of the oil seals in the Fel-Pro timing cover set when changing the opti, etc. I oiled the lips on mine, as per the generic instructions in the kit and standard seal installation practice). Then I learned there are some who believe the opti and waterpump seals should both be installed dry, as they are teflon and teflon seals often leak if oiled on installation (apparently the oil film prevents transferring a layer of teflon from the seal to the shaft). There was no debate about the crank seal -- oil the lips!

I just got off the phone with Federal-Mogul (manufacturer of Fel-Pro) and here is the skinny:

Install the optispark distributor shaft seal dry. This is the ONLY one that is teflon and should be installed without oiling the seal lips. The tech confirmed that oiling a teflon seal may actually cause it to leak (so far I have been lucky, but there may be another new seal in my future... )

DO oil the lips of the crankshaft and waterpump seals.

The technical support person I have been dealing with took the time to research their technical drawings and individual parts specifications before providing me with this advice. It is possible that other manufacturers may use other materials, but if you purchased the Fel-Pro set, I would follow their advice.

Did it leak, or is it "so far so good"? I haven't seen any sign of leakage from mine yet, still keeping my fingers crossed.
