Looking for some help with respect to a 2008 2.3L valve job.
We replaced the valves with new ones, lapped them, and tested with soapy water and compressed air - all valves were nice and tight. The problem comes when checking the solid lifter valve lash. Despite the fact that the new valves have the same dimensions as the originals, we’re finding a need to use different lifter ‘thicknesses’ to get it right.
The only way I see to check the lash would be to install each cylinder’s valves one by one (2 intakes, 2 exhausts), install the 2 cam shafts, measure between cam base circle and top of valve stem (using a fat stack of feeler gauge blades - which doesn’t lend itself to accuracy), then deduct the lash to establish the lifter thickness...then move on to the next cylinder. Does this sound right? Seems pretty tedious and time consuming, especially on an assembly line.
My questions are:
Thanks in advance - any help is greatly appreciated!

My questions are:
- does anybody know the factory procedure for setting the lash, or an easy method to set up the head?
- also, is anybody selling used lifters of various thicknesses?
Thanks in advance - any help is greatly appreciated!
