On a 2000 500hp 6nz with 340b Jake's what would be the optimal lash setting? On the Jacobs PDF download I'm pretty sure it's .035" +/- .003" peterbilt says .033" +/- .003" and I'm pretty sure I saw it somewhere else listed at .037" +/- .003".
Last time a mechanic touched my truck he did it the lazy man way and set them at 30 just like the exhaust valves and I could coast up an off ramp loaded and flip the switch on and off and you couldn't feel it, just made noise. I opened them up to 36 and it seemed to be an improvement. I'm going to run through the overhead this weekend and am just curious where to set them. It'd be nice to have a little more jaking power. I did go through and rebuilt them a little over a year ago so mechanically they should be good
