2004 lly oil draining out exhaust

[myztrain]

I have a 2004 lly and today replaced what i thought was a blown turbo. Symptoms oil draining out the exhaust, no boost, and a lot of oil dripping from under where turbo is mounted above. I Install a new turbo, now truck has boost, but oil still drains out of exhaust. I did oil change. I let it idle for 2 hours trying to burn of oil from exhaust thinking I was good from turbo install and wouldn't loose oil, trying to burn all oil from exhaust system. Reved truck up to 3000 and new oil shooting out. Puking out all oil. Low oil light on. shut off truck. Pulled dip stick and no oil on it...... Im lost being a back yarder.... not sure if pcv, turbo vane, head gasket, cracked piston??? does have slight rough idle and slight loss of low end power
