ive been reading this thread for a bit and wonder if =
i have
the same
problem. after leaving my 89 2.1 digifant vanagon sitting =
for a few
days i
heard a knocking sound on startup. right away i shut it down =
and took
a
compression test. 135 all the way around. one thing though, the # 4 =
spark
plug was very loose and showed sooty blowby all over the =
exterior of
itself.
the knock is more resonant than a tap, louder than a tick. =
and during
the
compression test (turning the engine over 5 times) it wasn't =
detectable
at
all.
are we still talking about the same thing? lifters, valve =
seats
etc...?
could the results i got still point to a more serious =
problem.
any
insight will be appreciated.
