back story just did an in frame on it new pistons, liners, bearings, loaded reman head (after market) got it put together and head set put the cams and rockers etc.. on. wedge and pin it for timing and start setting the over head. i can get the intake and exhaust valves adjusted just fine, when you go to the jakes you can not adjust them. back the adjuster screw all the way out and can not get the 7mm gauge in to adjust them. any thoughts or suggestions? i'm at a loss have done many in frames on these and heads and adjustments this is the first problem i've had out of one.

It sounds maybe to me like the engine was pinned in the wrong slot/place on the crank when building it,.. or one of the cams has slipped,.. or you are not aligned with the correct cylinder when adjusting the valves.

What is the detent clearance measuring with a dial indicator between the top of the valve(s) and the engine brake rocker detent position?

Fist and foremost, just to point out the obvious, ...

STOP PUTTING ENGINES TOGETHER WITH AFTER-MARKET, GARBAGE HEADS AND/OR INTERNALS THAT WILL NOT LAST A MILLION MILES NO MATTER HOW HARD YOU TRY AND WISH THEM TO!!!!!

My recommendation,... take the time to learn all the things recommended by this forum so that you can build an ISX to very high standards instead of folling the path of most shops.

Just some fair warning up front on here, no argument intended, I am the guy who says things like ...

"Repair shops hate my guts and my videos because I educate truck owners on how to use a torque wrench, or how to make a proper repair to a high standard. God forbid they end up in a shop questioning that lazy-man, air-gun happy bas$tard who might accidentally get offended if someone points out that they request a bit more professionalism and the use of a f$king torque wrench, so that things are done right for that $150+/hour."
