http://www.stovebolt.com/techtips/valveadjustment.htm I use a 2-3' 1"X1" board,to turn the engine over. place the board between the firewall,and starter button. I find a halfway comfortable position,to "sit",to find T.D.C.,of the pistons,(thumb over hole),while simultaneously pulling on the 1X1 "lever".(Board is anchored by starter button),to "bump" the engine over,using the starter. just rotate engine enough to feel the air escape. If it rotates any farther,you need to start over. It needs to be set at T.D.C.Just make sure truck is in neutral,and the key is "off". It took me about a 1/2 hour,(from removing the valve cover,to replacing it, after the truck got to operating temp. Two rotations to adjust all the valves! SWEET! Thanks,OLY!!
