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.
