Rebuilding tips

[Todd Humphreys]

I'm in the process of reringing my 1982 75hp johnny, what sealant should be used to seal the block? Next, is it a no no to use RTV sealant on the gaskets to help hold them in place or should all gaskets be installed dry? Finally, I noticed that alot of the bolts has the OMC peanut butter on the threads, is this necessary or can I use never seize (graphite) or is locktite suitable? Thanks to all the great info from this site.

Gel-seal is the proper sealent for the crank case halve's. OMC gasket sealer on the gasket's accept for the manifold gaskets( dry) As for the cylinder head, I could never keep this straight! you either use sealer on odd, or even day's. Joking aside! when using gel-seal,start with a fresh tube, make sure the surface is absolutly clean, and primed with loc-tite primer. Wash your hand's of grease, or solvent. The last place you want a leak is between the case halve's. I'm not joking about washing your hand's.

use gasket sealing compound on head gasket wether it says "do not use sealer" or not gaskets can dry while in parts dept. using gscp will remoisten gasket<br />also use gscp on bolts it makes them easy to remove later
