Injector removal/testing -how?-

[james accordino]

Have new seals for the injectors ready.  You can get
them at any online seller and have them in a few days.
 I also like to use a little lube like vaseline or
better silicone grease that they sell in a little
plastic tub in the plumbing section of Lowe's or Home
Depot.  Like $2.  This works good on any o-rings.
Just use a little bit.  Don't be afraid to pull on
them.  I use a stick levered against the valve cover.
It won't  damage either the lines or the VC.  You can
put them all in a plastic jug and look at the
patterns.  Just move one around by the line to observe
it's pattern.  You do loose the balance test by
measuring each injector with the factory tube jig.
But you can definitely tell if somethings amiss by
observing the individual patterns.  Also look for any
to be dripping say 2-5 minutes after closing.  That's
not good either.
