bronchus60 is on a distinguished road
Update: After a 3 wk. wait I finally got that Reman HPOP warranted. In fact, they sent two. So I put one of 'em in the hole and put some shop air pressure to it. Gone is the gurgling sound I was getting from the area of the HPO reservoir at 40 psi. In it's place, I am now getting a musical note from somewhere way down deep in the engine at around 90 psi. It sounds like a high-pitched hum or vibration in the key of G# in the fifth octave (I was able to replicate the note on my keyboard). Has any body experienced this phenomenon? Thanx!
