'71 Power Brake Booster Check Valve (and thermal sensor)
Ok, I disassembled my air filter housing. Visiblely, the parts are original but no rust of the flap door, nor on the shnorkel diaphragm.
I did re-assemble and aspire with my mouth and the flap raised up. Just a little bit because my mouth isn't as mighty as my carburetor. :D
Then, I tested with the engine running and the flap raised up too. Slightly more, but seemingly suffiencently to aspire the air coming from the exhaust manifold.
Also, maybe that the flap closure wasn't complete as the ambient air wasn't cold (15°C, 60°[email protected])
With an hot engine, the thermal sensor close the vacuum line and the flap goes down under the diaphragm spring pressure.
A perfect 51 years old operating system, Chrysler Corp. is the best. :thumbsup:
