1979 Firebird TA - Resurrecting the 'ol 'bird for myself and 16yr old son.
PROBLEM #1: I have a leak under the dashboard passenger side and center console area. A continuous dripping/light intermittent pour... upwards of a 1/2 gallon while it was running.
Question: What is under the dash in the firewall that would leak? heater core?
Considerations:
A. Brand new radiator... just installed.
B. Was running car to warm last 2 days - doing maintenance after sitting 2 years (adjust idle, check hoses, etc. )
C. Today checked level of radiator... About a gallon low... BUT -->> VERY black dirty looking water...
D. Flushed radiator.
E. Afterwards ran car about 15min... Leak appeared under dash... SAME dirty black looking water. About a pint leaked into plastic tub container I put down.
F. No water or bubbles in oil is visible on oil check dipstick.
Ideas Please? head gasket? heater core? lower intake manifold gasket?
Thanks in advance, Jay
