Tiny pieces of it in the air inlet fitting and the air regulator (where it's been wearing away material for some time). Absolutely crazy air pressure symptoms (pressure suddenly drops to 40 psi, engine stalls, and pressure then starts to climb while the engine is sitting stationary (back into the 90's).

^^^^ agree on that for sure, so could you isolate where the growler was coming from,compress,rail,ect……., I would think regulator bleeding back

It was the air pressure regulator, seat had been damaged (and as the pressure climbed back up after engine shutdown, it would squeal and open/close). Totally bizarre failure.
