<VV> HELP!... push rod tubes...

[Frank DuVal]

I agree, O-Rings seal without additional sealers.

They DO need lubrication to install, so they do not get damaged. 
Typically use the fluid they are sealing againt to lube for 
installation. For engine 0-rings that usually means engine oil. 
Powerglides, that would be Dexron. One one closed loop chilled water 
system that could have no petroleum products in contact with the water, 
K-Y jelly was the recomended lube, as the water would dry too quickly to 
lube well.
