I have tried doing this method as on that site, and still having the same problem, after i adjust the 8 valves when the #1 piston is at TDC, i go to the #6 pinston at TDC, and about 3 of the first 8 that were adjusted, the rocker arms are so loose that i can take them right off of the pushrod, and when i spin the motor over back to the piston being at #1 TDC, they are all tight again and i can spin the pushrod exactly how tight i could before, and the rockers all get tight agian, while the 3 of the 8 pushrods that were adjust when the piston was at #6 TDC, 3 of the rockers are loose enough now to take right off of the pushrod... if that sounds too confusing let me know, i am really lost here, are they supposted to be this loose? i have set them now about 3 or 4 times, and every time it is the same issue... what could it be? or are the rockers supposed to be that loose?
