Whats the easy way to test Intake Belly Pan leak. It's losing oil showing codes Runs good. Spark plugs and catalyst show lean condition.Can a leak be diagnosed with compressed air at teh nipple on passenger side of intake by forcing air lightly and or listening to where it goes?

You can remove the air hat from the TB with the
engine off and open the throttle. Look inside the
manifold and if you see oil the plenum is likely
busted.
