Head bolts

[john2189]

Should head bolts in aluminum blocks be dry or oiled when torqued?
Thanks

Into aluminum, ALWAYS use a good antisieze.

Probably really depends on the manufactures recommendations.

Best to consult the service manual for what your working on if possible!

I found a manual online (one of the ones that has bad print) and it says use motor oil on threads

I used to just oil them, til I ran into never seize! --- now thats what I use.

Are the holes blind or do they go into water passages? If blind holes I'd use copper antiseize. If in water use liquid Teflon. It will both seal out any water and will keep bolts from seizing up.

They are dry holes. The manual i found online says to use oil, but I put a dab of never seize on them

I don’ k you can go wrong using never seize.

I agree. Dissimilar metals don't play well with each other.

I don’t know what happened to the rest of the letters I typed but yes, use it.
