[Chevelle-list] Let's try again....

[Malibu]

For the vacuum advance, you may have a bad vacuum can. You can check this 
with a pump like the Matyvac.

These are great for one man brake bleeding also. At idle you won't have 
hardly any vacuum so the advance may not move much, if at all. But it should 
at higher rpm. Is the breaker plate stuck? It sat for several years.
As for the water leak, I would take it to a radiator shop and have them 
pressurize the system to try and find the leak. I think some auto stores 
will let you borrow one also. You could have a leak anywhere. Just because 
you see water at the bellhousing doesn't mean it's a freeze plug. Maybe the 
intake. Heater hose, water pump seal, head gasket. Any water in the oil?  In 
that environment, blowing from the fan, wind coming in at speed, vibration, 
it could be anywhere. Goode luck. Hope this helps you out.
