SOURCE: 2007 Chevy Avalanche burns oil.
IF ENGINE IS FRESH,NOT BEEN BEAT ON AND YOU KNOW THE HISTORY TRY THE PCV VALVE AND HOSE. PCV MAY BE RECIRCULATING THROUGH INDUCTION AND BURNING YOUR OIL. THIS IS ASSUMING PISTON RINGS ARE GOOD AND YOU ARE USING THE RIGHT OIL. SEE IF AIR FILTER IS DIRTY,IF SO REPLACE IT AND NOT WITH A K&N IT DAMAGES MASS AIR SENSORS AND FUEL MILEAGE WILL GO BYE BYE AND POSSIBLY DRIVEABILITY ISSUES. MARK DIP STICK AND TRY THESE FIRST. QUICK CHECK PULL OFF INDUCTION TUBE,OPEN THROTTLE BODY AND JUST LOOK IN FOR OIL IN THE INTAKE MANIFOLD.

Start up with the engine cold, should be 60-65 psi
Start up with engine hot and also running in gear idling 42-48psi
Any other readings could be a bad oil pressure sending unit or a oil pressure relieve valve which is located on the block where the remote oil line is bolted to. Good luck and keep me posted.

you may have bad horn, take a test light and see if power is going to horn when horn is pushed, if theres power going to it then you have a bad horn,if theres no power to it then check the horn relay. but il bet if the fuse is good then the horns are bad.
