Re: 96 5.7 Valve Tap

The engine has to be running to adjust valve clearance. To do this, you have two options:

1)buy a set of junk covers. Drill a hole in the covers over the rocker arm nut big enough to get a socket in there. I would use a deep-well socket on a locking extension to eliminate the possibility of droping the socket in.
2)get oil EVERYWHERE

I would go with option number 1. Start the engine and back off the first nut until you get more ticking. Tighten it down until the ticking stops, then tighten it one more turn. If I remember right, the book says 1/2 to 3/4 turn, but with hydraulic lifters, a full turn will be fine. Repeat 7 more times.
