Re: Project "Hulk Jr"

The rockers should be here today....

This is the valve adjustment procedure I am going to follow. Do you guys see any problems???

ENGINE OFF Valve Adjustment Procedure - The Quick and Accurate Way:
First, view this simple chart below for Small and Big Block Chevy Engines. Do you understand what it describes? A more detailed explanation follows below the chart. For other engines you will use the firing order that matches your engine to create a similar chart. This chart is based upon "opposite" cylinders of your firing order. (see below)

Intake Valve Adjustment: ENGINE OFF!
• with #1 cylinder Intake Valve at full valve lift .... Adjust #6 Intake Valve
• with #8 cylinder Intake Valve at full valve lift .... Adjust #5 Intake Valve
• with #4 cylinder Intake Valve at full valve lift .... Adjust #7 Intake Valve
• with #3 cylinder Intake Valve at full valve lift .... Adjust #2 Intake Valve
• with #6 cylinder Intake Valve at full valve lift .... Adjust #1 Intake Valve
• with #5 cylinder Intake Valve at full valve lift .... Adjust #8 Intake Valve
• with #7 cylinder Intake Valve at full valve lift .... Adjust #4 Intake Valve
• with #2 cylinder Intake Valve at full valve lift .... Adjust #3 Intake Valve

Engine "OFF" Hydraulic Lifter Adjustment Tips:
If the engine is complete and installed in the vehicle, warm up the engine by running it until it gets to operating temperature (15-minutes or so). "Cold" adjustments should only be used on new engines on as a preliminary adjustment on the engine stand. Once a new engine has been started and intial break-in procedures complete, readjusting the valves "hot" is recommended.
1. Have all necessary tools ready and then quickly remove the valve cover(s) while the engine is at operating temperature.
2. Begin the adjustment procedure by using the chart above, or one to match your firing order and opposites.
3. With the #1 Intake valve at FULL LIFT --- This means that you turn the engine by hand until the intake valve on the #1 cylinder is fully open (watch the rocker arm push down on the top of the valve stem, compressing the valve spring until it stops moving downward) --- and adjust the intake valve on "opposite in firing order" cylinder. Always remember, the opposite valve engine firing order dependent. Know your engine's firing order!
4. Go to ths opposite cylinder. This technical article uses the common firing order for small and big block Chevy engines as the example, so this would be the #6 cylinder.
5. Loosen the rocker nut (if using roller rockers there is typically a Jam Nut that you must first loosen with an Allen wrench) on the #6 intake valve.
6. Take two fingers and spin the pushrod back and forth between them to feel for resistance.
7. Carefully snug the adjustment nut and STOP when you feel resistance in the pushrod as it applies pressure to the socket in the rocker arm and lifter, this is considered "zero lash."
8. Turn the wrench 1/8 to 1/4 turn (see below) for performance, racing, or high RPM applications. Turn the wrench 1/4 to 1/2 turn for stock or mild street applications. For applications that regularly operate at consistent high RPM, use the slightly lighter setting of (1/8 turn).
9. If your valvetrain uses poly-locks, remember to reset (snug) the Allen screw
10. The adjustment for this valve is now complete!

11. Turn the engine by hand SLOWLY to the next cylinder / valve in the firing order.
12. Repeat the above steps, starting at #3 through #10, but use the next cylinder in the sequence. In our Chevy V8 example this is the intake valve for the #8 cylinder
13. Continue through all the intake valves and then start the procedure over for the exhaust
