The techniques are identical except you can't do it in two easy steps as one person posted.

The thing to keep in mind is you want the lifters on the base circle of the cam when adjusting. This is most certainly accomplished when you have the engine rotated to the point farthest opposite that point where the valve overlap occurs (one cylinder, exhaust valve is almost closed and intake valve is just opening). Due to symmetry, you can expect that the cylinder 1/2 way through the firing order will be ready to adjust when you observe a cylinder in that condition.

Huh?

I mean, if you rotate the engine until #1 valves are both just cracked (exhaust closing and intake opening) then the cylinder three "spots" down the firing order will be ready to adjust. (sorry, I don't recall the firing order or I'd tell you which cylinder it is!)

Then you just continue down the order until all have been done.

I am leery of the shortcuts.

I expect there is a "rule of nines" type method but the "rule of nines" doesn't always work for 4-cylinders either.
