Leaky injectors is just one of the possible causes for fuel contaminated
oil.
One of the more common causes of contamination is a bad ignition part, a
faulty oxygen sensor, or the oil itself. If you had a bad injector the
engine would miss or skip. To find out which cylinder is skipping, start
the engine and wait for the skip. Pull each plug wire in turn until you
find the one that either doesn't make a difference, or the intermittancy
turns into a dead skip. It's better to pull the wires from the cap than the
plug itself to avoid a nasty shock.
To check the pressure holding capability of your injectors, connect a
battery charger directly to the terminals on your fuel pump. The fuel pump
is located inside the frame rail under your sliding door. Look closely at
the fuel pump. The + and - are cast into the pump near each wire. Run the
pump with your injectors in the container for about 30 minutes. If you see
no leak you don't have an injector leaking.
Most Vanagon driveability problems are caused by simple tune up items or
corrosion at a ground point or in the fuel injection electrical connectors.
A Scotch-Brite pad and some electrical contact cleaner can do wonders for an
ailing fuel injection system. Just make sure to coat the ground terminal
with motor oil, grease, or cosmoline once you have cleaned it. The coating
will prevent oxygen from reacting with the ring terminal to prevent future
corrosion. Eastwoodco.com sells a Cosmoline spray that I love to use in my
restorations.
