Reading boltscience.com is like watching one of those blood'n'guts driver ed movies. I'll continue to use grade 5 hardware store bolts on my alternators and such, but critical fasteners, I'm buying new or known-used-once. I've long culled non-perfect bolts and cleaned out all stud holes etc. We gotta remember it's not the 90's or 80's any more, these fasteners are OLD OLD OLD, heat cycled and stretched. I know there's no real issues with the 199/232/258, I've always used used headbolts in my (dead stock power level) motors with Good Practice, but I'm questioning even that now. I'm saving examples of each head bolt for sizing and such, and tossing my substantial collection of old ones in recycling. I don't know where they've been or how many times they were torqued up. I probably won't bother with split lock washers anymore on anything. It seems so wrong though! I was wondering why newer cars etc don't use many of them; I thought they were just being cheap. Now I know. -------------- next part -------------- An HTML attachment was scrubbed...
