Dan,
    compression check will not tell you a thing about
your kind of leak.   I would sugest that you remove
the pushrood shield and the other engine shield that
covers the head.   If you have a head leak, you have
had one for some time but it just got bad enough that
you can see it.   On the other hand you may just have
a hose leak somewhere that could be fixed in a pinch.
"how's that for a punishing pun".   Look at the head
and look for crusty dried antifreeze drippings?   Best
time to spot the elusive leak is on a short run or a
cold night.   Short runs pump up the pressure but not
enough heat to vaporize the coolant"10 minutes".   Get
back to us when you spot the leak.   gary

Subject: leak tests

Volks,
In trying to isolate my coolant leak, I'm wondering
what each test will
tell
me.  If I've got a head leak, does it stand to reason
that it will show
up in
_both_ a compression and a coolant system pressure
test?  Maddeningly
and/or
luckily, I took the bus for a spin last night and
checked it for leaks
once I
got home.  Nothing, nada, zip.  No peeing like on
Friday.
Follow-on: anyone have a reference for a coolant
system tester (there's
one
referenced in the Bentley, but can I use any of the
ones sold down at
my
FLAPS)?

Best,
d.
