Question about Toyota Cars & Trucks
Very carefully my friend. Kidding. Ok, remove the valve cover and anything in your way of removing it. By hand, with a socket and ratchet, on the crankshaft bolt head, turn the engine over to get #1 piston to top dead center on compression stroke. You'll need to find out what the valve lash should be in order to adjust properly, I run the 22R engines and only have specs for that, and have a feeler gage to place between the valve head and rocker arm. Check the gap on the intake valve for it is in position to adjust now because the cam lobe is at the farthest away from the valve. If it needs adjusted closer, turn the nut loose and screw the center in to tighten and out to give more gap, then tighten the jam nut after adjusted. Now turn the crank to bring #3 to top dead center and adjust that intake. Once done go back to #1 exhaust and adjust it. You'll know when the #3 is TDC when the rocker is loose on intake valve along with #1 exhaust. Now bring #4 piston up to TDC and adjust intake valve. Like I said, you'll know when it's @TDC when that rocker is loose, but with the spark plugs out you can stick a screwdriver in the plug hole to be sure it's up. Firing order on 4 cylinders is 1-3-4-2 so do your adjustment in that order for each intake valve and go back to the last one adjusted and do the exhaust valve.
