Hissing sound when turning off motor...
Hey guys,
There's a hissing sound coming from the engine. It lasts for about 5 seconds and sounds like pressure is bleeding off from somewhere. Where should I look for this? All the plugs are tight, its pulling strong vacuum. :confused:

Headlight relays.
I had a small vacuum leak in one... did exactly the same thing.
Good luck! :cheers:

First where is the hissing coming from? Front part of engine bay, check the radiator or coolant hoses, or vacuum hoses. up front by the headlights. If the noise is more near the engine maybe check the hose going to the booster or other vacuum lines bhind the carb.

Take a pinch clamp and pinch off the vac system at the intake manifold before shutting it down and see if you hear anything, then shut down the eng with it still pinched and see if you hear it.
