Yeah, you should be able to hear it if it doesn't have a bigger leak somewhere else.
I did take the oil cap off while it's running, no oil mist, light pulses of air. Same with the black box on back it's vta and unfiltered (probably bad) but if oil was coming out of it the cross member would be getting showered, everything is bone dry behind the engine.
My head isn't super dirty either, I just don't like the stupid angle the plugs are at. Though, I'm just getting myself worked up, the time that I started to crossthread one it was nearly dark outside.
