I did a search of this topic on this forum , however, it did not provide much information...
For an aluminum block/head , 4 stroke, older "L" head like a Briggs and Tecumseh, are you using antiseize paste on the steel head bolts threads when you install them? If so, does this effect torque values? That is to say, do the torque values need to be adjusted (reduced) due to the lubricating effect, to avoid over-torquing the bolt? (And if so, by how much?) As I believe that some of you know, my son and I restore these old engines, most of which are 40-60+ years old. We have had some REAL challenges removing the head bolts on these engines, presumably due to the electrolysis reaction between the steel bolt and the aluminum head. We have never used antiseize before, however, I wonder if we should be so they will be easier to remove the next time We have only been cleaning up the bolt threads and threaded bosses, and installing and torquing the bolts "dry" . Our repair manuals make no mention of "dry", "oiled", or "antiseize" when reinstalling the bolts. What are you pros doing?
Thank you in advance for any help.
