Major oil loss

[JrBradley]

I have a 2004 with 5.9 C i parked the truck last week because in 3 or 4 days of comuting about 70 miles to and from work i put 2 gallons of oil in the truck
-turbo is dry
-blue smoke when cold (have not checked when hot)
-my thoughts are, rocker cover, head gasket, rings or valve seat.
Am i missing something easy to check?

Edit- not much oil under truck when sitting

It may be a good idea to visit 3rd gen truck forums at either: https://www.turbodieselregister.com/forums/ or https://www.cumminsforum.com/forums/
