Working on a friends 1961 GM 4106 and trying to find the source of an air leak. The beams are not pressurized. I dropped the bag and expected to find a leak on top. But nope the bag was holding pressure and the fitting didn't bubble when sprayed with soap solution. No other leaks detected in the air lines and fittings that run in the beam. I am going to look hard at the other end of the beam where there are some regulators. I just replaced the leveling valve I believe the exhaust was leaking on it, but not a lot. And not the source of the noise. It's only after 90psi which is why I'm looking at the regulators at the end of the beam next.
