Valve adjustment sequence

[hemmah]

I want to make sure I got the valve adjustment correct!

From the tech note: when the engine is at TDC for piston #1, it’s time to adjust the valves for that cylinder. Both the intake and the exhaust valves can be adjusted at the same time. Now, rotate the engine crankshaft 120 degrees using the fan pulley. There is a mark on the crankshaft engine pulley that will indicate the 120 degree position. Now, repeat the adjustment procedure for cylinder number six. When finished, rotate the engine another 120 degrees, and adjust the valves for cylinder number 2.

This is the confusion part:
Repeat the rotation and adjustment procedures for the remaining valves following the engine firing order 1-6-2-4-3-5.

I have just adjusting number 2 valves, then I rotate 120 degrees more am I at number four cylinder? and adjust #4 valves? Then I rotate 120 degrees more am I at number three cylinder? and adjust #3 valves? Then I rotate 120 degrees more am I at number five cylinder? and adjust #5 valves?

Then I repeat check with the same 120 degrees incremental movement and check adjustment on respective valves? 1-6-2-4-3-5


Thanks,
Steve

Just use the ignition rotor as your guide. Whatever cylinder the rotor is aligned with is one that can be adjusted. Want to adjust #4? Turn crank until rotor is aligned with firing #4.

You have it right. Once you use the rotor to get you to TDC Firing on #1, you don't need to reference that again. And you can always check before doing any adjusting to be sure that both rockers on the cylinder you have moved to will wiggle. Use a good flashlight, and look in at the cam lobes, too. You can see when a rocker is on the cam base circle.

Me, I cheat. I do #1 (though you could start with any cylinder which is at TDC Firing). When under the car I then feel around to see which of the other exhausts are loose. Some will be. I adjust those. I do the same when back up top. Then I turn the crank 120 degrees (to the mark) and repeat. I think there is a way that you only have to turn the crank once, and maybe not just 120 degrees, but since I can't remember I'd just do the 120 turn, and then another. I'm pretty sure by then you will have gotten all of the valves to their adjustment position.

Less moving around that way.

But the by the book method works, and is methodical to be sure.

Thanks, I got it done. It makes sense. A little wiggle is good.
