When I blew air into the dipstick to find the source of oil loss, I had to plug the hose that came out of the back corner of valve cover and into the air intake, otherwise I could not get any pressure into the engine. Is that what you mean?

Excuse my ignorance (I'm new to the Mazda world), but what is OG (I saw that stated in several threads but can't figure out what it stands for).


Appreciate the lead on possible donor sources!
