I'm going to put on my 1.6 rockers today. I know how to do them, but I was wondering how to adjust them properly without the engine running so I don't bend or break anything on the initial startup. The instructions tell me to adjust the intake when the exhaust is starting to open and to adjust the exhaust when the intake is almost closed. Is this basicly telling me to make sure there is no cam lift at all on the valve I am adjusting?

Make sure the valve you are adjusting on is all the way closed.Take the push rod between your fore finger and thumb and rotate it while tighting the rocker arm.When you feel ressistance on the push rod stop.Then thighten th rocker 1/2 to 3/4 of a turn more.That will get ya pretty close.

This is straight out of the GM service manual:
Line the mark on the harmonic balancer up to TDC of #1 cylinder firing position.
It will be the firing position when both #1 valves are closed.
With the engine in the number one firing position the following valves may be adjusted:
EXHAUST: Cyl. 1, 3, 4, 8
INTAKE: Cyl. 1, 2, 5, 7
Turn in the rocker arm until all lash is removed. This can be determined by rotating the pushrod while turning the rocker arm nut. When the play has been removed turn the rocker arm nut one full turn. (I go 1/2 turn)
Now rotate the crankshaft one complete turn, to adjust the remainder of the valves.
With the engine in the number six firing position, the following valves may be adjusted:
EXHAUST: Cyl. 2, 5, 6, 7
INTAKE: Cyl. 3, 4, 6, 8

Then it says "Install rocker covers" <--lol

I use this way at work its easier than adjusting them when its running, and it makes a hell of a lot less mess. You can also look at the rotor position on the distributor to see what cylinder it is on at TDC.
