COMP Cams 104 Engine Assembly Lube, 8 oz. Jar

this stuff works great.feels dry for a lithium base lubricant.you can feel the zinc and molyedium in it.also it speads easily over bearings and stays there doesn't run off like other lubes.i will only use this stuff from now on.it works that good and its really reasonably priced here on amazon.this stuff is fantastic when installing pistons.you smear some in cylinder bore then install piston and rod assembly.do not dunk your pistons in oil.why would you put oil on top of your pistons and in between your rings?are you trying to create carbon build up.after you install pistons turn engine over and put some oil on piston wrist pins to lube them.Keith black taught me this procedure many years ago at an engine building seminar.note always use zinc when building old school engines!best break in lube there is!and if possible Prime the oil pump before start up.I used to use lubriplate lube this is better as it has zinc in it.I have built 100's of performance engines over the years.I don't even know how many engines and transmissions i have built for GM over the years in the thousands im sure.so trust me comp makes good stuff!

Nice Product

Picked this because it won’t run off a cam if the engine sits for a while before being started. Really wish the jar had some type of seal so I could have confidence that it never had an opportunity to be opened/contaminated before making its way to me form Comp.

Perfect for the application.

Will buy again
