hi guys im about to put my intake manifold on and noticed the bolts are covered with something but cant tell what. (old stuff, not new bolts). should i put them on bare? thread sealant? antiseize? thanks i really need to know

 

Anti seize would be fine, but the bolts dont go into coolant passages on the intake, so thread sealant is not required.

 

thanks doc

 

You can wick oil through the center two bolts, teflon sealant corrects that, it's also what the factory uses.
