  1. I'm in the middle of this job right now, and, unfortunately, it's every bit as tough as I've heard. Still, I know that a lot of folks have been talking/thinking about doing it, so I'm posting up a few photos that might prove helpful. (I actually have quite a bit of video recorded too, but am not sure now if I'll end up posting that on YT or not...) Notes: Give yourself a lot of time to do this job. I could see this taking a couple days of labor for the average joe, plus you need to measure and order shims, wait for delivery, etc. Try to label everything well and put parts/bolts/nuts in baggies with notes, to keep track of everything. Plenum has a lot of stuff attached to it and around it. Shims are 34mm in diameter and vary in height, of course, to set the clearance. One source of shims: https://www.yotashop.com/valve-shim-toyota-4runner-pickup-truck-t100-v6-3-0l-3vz-e-1988-1995-valve-shim-3vzvalveshim My 91 Warrior has about 83,000 miles on it and I'm finding that all of the 6 intake clearances are good (borderline, but good), and all of the 6 exhaust clearances are way tight. Pretty much the norm, from what others have said. I think the recommended special tools are a must on this job, but even those can't help on some of the difficult shims, next to the firewall. In those situations, when the brake booster (or something else) is making things very difficult, use a 3/16" allen wrench to lever the bucket down—because there won't be enough room to use this wraparound-the-cam wrench tool. After pulling a shim for measurement, put it back in the bucket before you turn the engine again. I've seen bad stuff happen before when a cam lobe catches the edge of an empty bucket. starting the project driver's side view clearance specs from hood label intake plenum removed (plug those holes immediately and clean/vac surrounding area well!) driver's side valve cover removed: cylinders 2 / 4 / 6
  2. At long last, after replacing my plugs, wires, distributer cap, ignition coil, and fuel filter, I have discovered the cause of my Dolphin failing under load and idleing rough; the Idle Air Control Valve. Unfortunately, this part has been a booger to find. Does anybody have one for sale or know where I can locate one? Obviously, salvage yards are a good option, and I've been to a number of them, just haven't found a 22re with the part still in it.
