Valve Adustment
I was going through the factory service manual and came across a section on adjusting the valves. I had always assumed that this engine had hydraulic valve lifters and there was no need to adjust the valves. The manual details the adjustment procedure and it appears that the FJ engine has solid lifters instead of the hydraulic design. The procedure also looks to be a major PIA as it requires exchanging the lifters in order to alter the valve lash. That means that you would need to do the measurements and if they are out of spec, you would have to get a different lifter of the correct height. I doubt that the dealers stock all of the myriad lifter sizes that might be required. That means placing an order and waiting. Then install the new lifters and check again. If still out of spec, rinse and repeat. See what I mean about the major PIA? Hopefully I am misinterpreting the service manual and a valve adjustment will only be required after an engine tear down/rebuild or a valve job. Twenty four valves is a bunch to deal with!
