Haynes stinks. ft-lbs for rocker arm nuts?

[nitrohuffer]

The rebuilding has begun and my Haynes manual doesn't have the ft-lbs for the 5.7l rocker arm nuts. It's a pretty important step or my rockers won't be rocking. Can anyone help me?

 

[lowlife]

year and engine code?

Valve Clearance Adjustment




Turn the valve rocker arm nuts clockwise until all of the valve lash is removed.
Turn the crankshaft clockwise until the alignment mark on the crankshaft balancer is aligned with the notch in the engine front cover tab.
Look at the number 1 cylinder valves as the crankshaft balancer alignment mark approaches the notch in the engine front cover tab. If a valve moves as the alignment mark moves into position, the engine is in the number 6 firing position. If this happens, turn the crankshaft clockwise 1 revolution in order to reach the number 1 cylinder firing position.



With the engine in the number 1 firing position, adjust the exhaust valves for cylinders number 1, 3, 4, and 8 and the intake valves for cylinders number 1, 2, 5, and 7.
4.1. Turn the valve rocker arm nut counter clockwise until the valve lash is felt in the valve pushrod.

4.2. Turn the valve rocker arm nut clockwise until all the valve lash is removed.

Zero valve lash can be felt by moving the valve pushrod up and down between your thumb and forefinger until there is no more up and down movement of the valve push rod.

4.3. When all the valve lash is removed, then turn the valve rocker arm nut clockwise 1 additional turn (360 degrees).

Great info!

This for a 95 5.7l I don't know the code, so I assume the info is the same. What does positive lock mean?

 

[lowlife]

engine code is the 8th digit of your VIN.. but this info should be the same as the 5.7 didn't change much from 95 to 99. In a nutshell, every small block from '55(?) up to 99 or so used adjustable rocker arms. Basically rotate the engine until the valve you are adjusting is onthe base circle of the cam shaft lobe (ie. no lift) tighten the rocker arm nut until there is no freeplay in the pushrod and add 1 full turn. keep in mind that this theory assumes that the lifters are pumped up (full of oil) if your engine has been apart for more than a few hours you may need to do this and runthe engine for a few minutes to circulate the oil and then reset the valves again.
