Comp Hyd Roller lifters #885

Yep, only 1/12 turn after zero lash. I just moved the adjusting screw on the roller rockers to zero and then, using the 12pt lock nut as a guide, moved it 1/12 turn more.

A few weeks ago I took it on a 175 mile trip that involved lots of continuous steady boost as I climbed mountains - then when I reached my destination, the competitive nature of all the car guys had us going WOT to hard brakes back to WOT as we ran thru the mountain roads/switch-backs and lots of long boost periods.

That was my final test, it passed :)
