Default Re: water in the oil

Thread sealant aka permatex is really only needed when a bolt hole is open to the water jacket. I always tap the holes, and wire wheel the bolts, then apply a thin film of copper never sieze to the gasket (both sides) and the bolts. I also do the paper gaskets... glue them on to a clean surface, then some neversieze on the one face. Stuff always comes apart and can be re-used without destroying the gasket.
All the joints do need to be clean and flat. Always pull the head down from the center out. A warped head will pull flat. HEAVY corrosion around a water jacket can be addressed with JB weld.
Theres also the subject of anaerobic sealants. Works like locktite only way thicker. Itll actually make a plastic film on the gasket surface where any bad imperfections are to be found. ws

Freshly decked block by bluing and draw filing. The original factory decking machining marks actually showed up! Last pic shows the begining of the seat reaming. Im way up in northern Wisconsin and dont have the luxury of "dropping" the stuff off at the machine shop, so I do it like farmer Fred wouldve done in 1930. Ive also cleaned heads by dragging them in a figure 8 on the concrete sidewalk... what ever works, eh?
