I have always used loctite 574 on case halves and cam towers with success. But on my 3.4 I am following Henry's advice and using threebond 1104 on the case halves and cam towers. Oil on the viton through bolt orings and threebond 1211 on the #8 (which I normally install dry). Oil on the viton oil return tube o-rings and curil-t on the main seal and cylinder base gaskets (which I normally install dry).

I figure it is best to experiment on my own motor to see what I think of these sealants. I don't mind pulling it out again in the winter if it turns out my previous methods were better. Would hate to have to do that with a customer though!!

Cheers
