Hello Scott,I got everything at 1/4 turn past what I thought was zero... Very close to where it should have been. Pretty neat just knowing when it will start clacking...and the thrill of when it doesn't so you can have hope you're making things even better..lol
Wish I knew how to make these things behave.... Like number 2 intake was a little ticky...redid my adjustment and it quieted down...
tried the same thing with number 6 exhaust and it doesn't want to change it's tune but I know it can be quiet... I think it was even quiet the past time I start the truck..I mean, you can't hear it over the engine.... But you know it's not as smooth as the others....even bumped it a little tighter but no luck... I mean, I know I can't go an entire eighth turn more right?? I don't think it would matter anyway the way these things act.....
Going to tear it down tonight to get the intake gasket replaced....God willing of course...
From your comments I can tell that you actually *do* know how to make these things behave.
As a matter of fact, if you were turned loose on a freshly rebuilt motor with all new parts you
would be astounded how each of the 16 individual lifters would act identically to each other as you
went through your running preload adjustment. It's amazing. Just like that guy in the video,
where he just cycles right through all the lifters in nothing flat.
But on a high mileage motor each of the 16 lifters develops a little 'personality' based upon any
normal wear on the outside and varnish accumulation on the inside. As you now know from
firsthand experience, it can be a little confusing working your way through all these variables
on your first running valve preload rodeo. :0)
You will find some people would have a problem understanding why would you put all this effort
into a high mileage motor instead of just building a new one? My answer is that it's much better
to learn these techniques on an older engine *first*, and then when it's time to set up the new
motor with the proper preload (cold then running) ...it will be like riding a bike. You will be able
to easily master the hardest part of dialing an engine in.

In the old days of pen & paper you would document that the 2I and 6E valves stood out during the
adjustment process, but the other 14 were pretty equal. IF you were to remove any lifters for
an exploratory during the upcoming intake manifold re-gasketing, these would be the 2 to do.
But since we're doing all this collaboration via computers then these valves are now documented
in this thread for posterity.
And finally, this past setting is all that you are going to get from the external adjustment. And
I would let this ride as-is for now. And if you want to make any further improvements, then you
will need to identify which valve(s) are noisier than you are comfortable with, and then decide
if you want to inspect (and possibly disassemble) just the noisy ones.
Food for thought.
