Head Bolt Lube

[AaronJ]

I'm reinstalling the head on my Yanmar 2GM20F. The Seloc manual says to apply motor oil to each head bolt. Is that good enough or should I put some anti-seize on them? Thanks!

Anti-seize is better if you ever want to take them back out. There are many different torque spects. Some are for dry, others lubed, and some for plated bolts. Anit-seize is better then oil, for it will not scrap off between mating surfaces allowing for a full torque before possible galling.

Molybdenum Disulfide is a great heat resistant anti-seize lubricant that can be used on things like head bolts, oil filter gaskets, etc. It makes things much easier to remove the next time you need to do so. Here is some info on it :
