This subject comes up from time to time, but I do not recall a definitive answer being mentioned as to what engine position will line up the oil holes in the cam journal to let oil pass through and up through the block and to the valve train. It may have been mentioned, and I missed it. But anyways, here is an observation I made while I have the head off.
Rotating the crank by hand bit by bit, I finally found it. Pistons 1 & 6 are at bottom dead center. At this position I can turn the pump by hand with a screwdriver and oil gushes out of the block oil hole. Doing it by hand lets me think my pump is decent shape. But even though I have # 1 on bottom dead center, I do not know which stroke I am on. I guess I could drop the push rods back in and figure it out, but they are sorted and packed away for now. I marked the flywheel, so I have a 50/50 change of getting lined up again and when it is all back together, I will determine which stroke of #1 BDC is the one & I’ll update here. Just to note, when 1 & 6 are at BDC, 3, 4, 5, & 6 are at even height where 2 & 5 headed down, and even up with 3 & 4 headed up.
Now, if by some chance Toyota did not drill all their cams in the same position and just did it random, this info would be useless. But it may be a starting point for someone searching for it.
