racing beat recommends hylomar. they've done this for just a little bit https://www.nopistons.com/forums/pub...>/rolleyes.gif so i think they know what the best tricks are. although when i built my motor dor my 1st gen, i used petroleum jelly.



maybe i'll try the vicks vapo-rub thing....that way when i fire up the bridge for the first time, people will smell it and think there is a mad duck with a cold under my hood https://www.nopistons.com/forums/pub...#>/biggrin.png wauk wauk wauk wauk wauk

I know it is mainly to hold the seal in place, but I think there is a secondary reason. It is fundamentally wrong to install any kind of rubber gasket or O-ring without lubricating it in some way. The vaseline, hylomar, and silicone all let the seal move with very little friction as the parts are clamped together. I guess in this particular application there is not a lot of moving, but I still feel better with some kind of lube on the entire seal.



Thanks for all the input!
