Smoke on a Lincoln Ls 2002 on 2002 Lincoln LS

Had white smoke coming from under the hood. I did a tune up and found oil where the spark plugs are. I know this signifies and blown head gasket however. I DONT HAVE water nor coolant in the oil on the dip stick. No oil in the coolant res. Now I have white smoke coming from the tale pipe. Didnt have this before. Figured that was oil burn off but it gets worse after I rev the car up to 3000 rpm. Could this be caused by a Valve cover gasket gone bad?????

Thanks. I also heard a pop so I think I blew out one of my plugs.
