B1B Keven Posted July 28, 2017 Report Share Posted July 28, 2017 An hour of searching and I'm done. Which 218/230 head bolts get tread sealant? Quote Link to comment Share on other sites More sharing options...
Merle Coggins Posted July 28, 2017 Report Share Posted July 28, 2017 Be safe and do them all. It won't hurt on the ones that don't go into the water jacket, and will certainly help those that do. 1 Quote Link to comment Share on other sites More sharing options...
Don Coatney Posted July 28, 2017 Report Share Posted July 28, 2017 I did them all. Quote Link to comment Share on other sites More sharing options...
pflaming Posted July 28, 2017 Report Share Posted July 28, 2017 (edited) I asked a local auto machine shop what he did, he concurs with Merle and Don, he does them all also. I was advised some time back to tap the threads AND that, this I didn't know, there is a tap for holes that dead end. Good advice.

NiftyFifty Posted July 28, 2017 Report Share Posted July 28, 2017 Flat tap or a tapered tap...very handy to know about those....and left turn (reverse) drill bits when you snap off a bolt. Get yourself some PTS sealer from permatex, great stuff in a tube and easier to apply...but if you buy the new headbolts from Summit, they already come with it pre applied.

In, sealed and snugged to about 25 lbs. Need to borrow a torque wrench.
