Another funky noise (1 Viewer)

[poldo]

I have a new noise
sounds almost like a belt noise while running (but it isn't)
then when the engine stops with the key off
it sound like a tea kettle for a few secons almost like it buids steam and releses it when stopped. a vacum is my first guess but from where ? it sound like it's coming from uder the tranny area
I thought about a header leak but it doesn't come from the manifold
and the exhaust is all new ???

Have the wife or a friend drive the truck, when they pull into the driveway jump under the truck and find out where its coming from.
If the exhaust is new, thats the first place I would start.

it's a 78 2F with Holley carb it's been desmogged I think it was done correctly
I have been listening carefully and I am thinking maybe a bearing but that doesn't explain the whistling when the engine is turned off
I can't think of anything else that can help pinpoint this weird noise...

A guess:
May be a broken baffel in the muffler rattling around and sometimes it blocks the outlet. It sounds like a tea kettle until it shuts off. It falls back down and it is fine when and you restart. Starts up again when you hit a bump.
