It can get a bit unnerving getting them to 60, so in my 276 build I settled on 40 as that was so much tighter than how they feel right outa the coffee can.
I started my wrenching oddessy almost 60 years ago with small engines, later Japanese and British motorcycles, then VWs, and toyotas, both four and six cylinder types. I adjusted a lot of valves. I have only worked on one engine with hydraulic lifters, and that was sooo confusing.
Lately I have been talking a lot about utilizing a jamb nut on a johnson (or offshore) lifter. Some of you are getting tired of hearing about it, but really in all these years of the damn things bouncing up and down on rocker arms, some of which were on honda motorcycles with a 10k redline, I never pulled a cover and found a loose jamb nut. Ever. And there was no torque specified, just tighten.
My son just appeared towing the big 8 way log splitter from his work and needs help on the repair, so I'll end this post with 2 photos and get back later. Feedback is good, and the short one is at exactly what a handfull of Henry's are. There is room to shorten a bit on threads.
