They are not hydraulics, my error as they are still solid lifters that have shims that require little or no adjustment. I would be interested in finding out what the hours are to adjust the valves as they are not that same as old school lifters.What year did the 4.0L shift over to hydraulic lifters? My '06 4.0L (1GR-FE) has mechanical lifters.
I kinda thought they were mechanical on the Gen2 V-6. My Service Manual only covers 2005-06. There may have been a change on the later Gen2s.They are not hydraulics, my error as they are still solid lifters that have shims that require little or no adjustment.

Read an article that best time from dealership for valve adjust on V6 4.0L is 7 hours. But also said most motors really never need it.I kinda thought they were mechanical on the Gen2 V-6. My Service Manual only covers 2005-06. There may have been a change on the later Gen2s.
The Service Manual has a very detailed set of instructions. How to measure, how to set, positions for measurement, which valves to measure in which position, how to choose the proper shims, calculations to determine shim thickness......... fairly exacting work.
I suspect its at least an 8 hour labor for a skilled mechanic. A DIYer......probably a couple days per side.
