360 Damper Install

for the bolts which go into water jackets (all the one which aren't blind holes) , I coat the threads with Permatex #2 (?). It's the brown gooey, messy stuff in a short little plastic bottle with a brush applicator attached to the lid. You put it on the threads of the "wet" bolts to seal the water jacket bolts. It's good because it doesn't harden and if you have to loosen bolts for any reason, you don't have to pull bolts, clean the threads and reseal them. Personally, I use dry, dummy bolts for the water jacket bolts, first, until gasket cement has cured on timing cover, so the gooey thread sealer doesn't contaminate the fresh uncured gasket sealer when first assembling. Then you can replace the dry bolts with the final wet bolts, one at a time, in a less hurried, less messy fashion.
