Real-World Repairs for Real-World NOX Failures 200

John, you most eloquently made a point for me. As anyone who has not as a pilot taken an aircraft to flight would instinctively know, a couple tons of airplane could not possibly remain in the air. The gap between instinct and science must be immediately closed on your first take-off with you at the controls, regardless of how many hours you have flying your hand out the car window.

More down-to-earth(!) it still seems a bit odd people will evacuate their AC systems by connecting a passive device to an air compressor. Or modulate the EGR valve in my early k-jet according to the pressure differential between two points along the megaphone shaped intake duct. It is one of those things you (I) have to see and feel to become completely real. The donut gasket story is an example of that.

Have you ever connected a manometer to the test port on the downpipe? I think that is done routinely as a check for clogged cats, but I'd like to try it to get a baseline. I think the port is an M12-1.5.
