Subject: replacing noisy lifter for 91 multivan

Albert,
If I were in your position I would give some
thought to adjusting the valves before you replace the
lifters. These hydralics lifters are a bit of a
moving target and perhaps the bad lifter is weak and
not all bad. To adjust the lifters you can use the
distributer to tell you what cylinder you are working
on. The notch in the back pulley indicates TDC for
two of the cylinder. If you put a piece of tape on
the back side it will be easy to find tdc for the
other two when the tape is at the bottom of the
engine. I would begin by documenting the current
lifter settings. gary

The light tapping noise on starting the engine been
going on for a
while, but
this time it just keep tapping very loud, and no sign
of quiting. I
have try
the MMO trick, did not work. Because of the different
tapping pattern
this
time, I am hesitate to drive it on the highway for 10
- 20 minutes,
afraid
that too much heat might burn the head gasket. I have
therefore decide
to fix
the source by replacing the possible collapsed lifter.
It doesn't seems
to be
too difficult to do. I have the Bentley manual to
refer to and have
obtained
lots of information from the Archieve. However, there
are several
simple
things just cannot be found in the book.
1. When I turn the cranshaft to set cylinders 1, 2,3,
and 4 to TDC, how
do I
know which valves/lifters belong to which cylinders?
2. My vanagon has auto trans, do I turn the center
large pulley bolt to
rotate the cranshaft with the transmission in neutral?
This bolt is
really
big.
3. The manual says rotate cranshaft 180 degree, and
adjust the next
cylinder.
Does it mean clockwise direction? Can I judge my
watching the
distributor
rotor?
Any suggestion will be really appreciated.
Albert
