Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hello I will help you with your question,
The key is to look at the exhaust manifold/ The exhaust ports are a straight shot to the valve so you can identify the exhaust valves and install the longer push rods for those valves/rockers.
The order from the pulley end of the engine on the back bank is I,E,I,E,E,I
The intake springs sit higher than the exhaust and the exhaust valves are canted further from the cam so the rod are longer
Just a couple more clues to be sure you get them in the right order
let me know what I can do to help
thanks when i pull the push rod out of the engine from left to right from the front of the car E. I. I . E. I . E. E / 6.0 I / 5 3/4 ALSO WHEN I TIGHTEN DOWN ON ROCKER ARM THE BOOK SAYS 168in wich is 14 lb also it says rotate an additional 30- degrees do i have to rotate additional 30 - degrees
The procedure I use is to tighten to 124 inch lbs (10 ft lbs) then tighten 30 degrees further
I am no sure what you are telling me above, the longer rods are the exhaust not the intake.
Lose the left to right and refrence all positions to the front (pulley end) of the engine and the front and rear banks
Forget about the order just put the longer rods on the exhaust rockers and the shorter on the intakes. It is easy to see which valves are the intake (higher springs and closer to the cam) and the exhaust (lower springs, further from the cam and canted over more)
The exhaust pushrods are 6.0 inches in length and the intakes are 5.75 inches long.
