| Now you can see what goes into
adjusting a valve. My cam specs say to use a .028" valve lash so
out came the feeler gages. Now when you adjust valve lash (the gap
between the rocker and valve stem), you don't want to slide the feeler
gage straight in. You want to have it enter from the side because of the
roller on the end of the rocker. The roller bearing makes it to easy to
slide the gage between the two giving you a false reading so this is why
you always enter from the side. By turning the end wrench a small amount
at a time, you sneak-up on your target adjustment and when you get
close, you then tighten the set-screw with your hex key like a jam nut.
Now you just don't do this at random, you have to know where the heal of
the cam is at all times. This way your assured that the lifter is not
starting to climb the cam lobe and giving you a bad adjustment.
How do
you know where the right spot on the cam is while your adjusting? It's
easy once you know and it goes like this...'when the exhaust valve just starts
to open, adjust the intake. When the intake valve has opened and is about half
way closed, adjust the exhaust'. This is the way you adjust any cam type
whether it be a mechanical (like mine) or a hydraulic. There might be a
test on this later so you better read it again if you didn't get it the
first time :-]
