First I want to thank you guys in this forum. You always help this dummy out even though you don't have to, and I appreciate it. This is a great community.
Details again: Gm perf 350 ho, hydraulic lifters, flat tappet cam. Attempting to adjust valve lash to eliminate a clacking sound I was getting. There seems to be competing methods to adjusting the valve lash.
1) Turn engine manually until cylinder 1 intake closes and piston it on compression stroke. Set lash on both intake and exhaust valves at the same time. Move laterally down the engine bank doing the same
2) Same basic method but follow the firing order. Once cylinder 1 is complete the intake valve for cylinder 8 is open. Rotate engine until closed and set lash on this 2 valves. And then follow through the order.
3) E-O I-C method. Pick any cylinder, rotate the engine until the exhaust valve begins to open then adjust intake lash. Continue to rotate the engine on the same cylinder and when the intake valve opens and cycles and is about to close adjust the exhaust valve.
Thoughts?
