First time vette owner with a 66 automatic and noticed after driving for about 5 minutes at 30+ mph about every 14-17 seconds I would hear a "Chirp" of what sounded like pressurized air escaping around the tunnel/firewall area. Is this from a pressure relief valve for the vacuum system or something more serious? Thank you

Instead, please find the correct section, based on the generation of the Corvette.
Go back to the main forum page:

Now start to slowly scroll down until you see your generation of Corvette listed.
C1 or C2 (1953 - 1967)?:
