Sounds like the head gasket to me. Oil will leak into the bore(s) over night giving the smoke on start up. Also the cylinder(s) will be pressurising the crankcase and breathers causing the filler cap to blow by.

Excess crankcase pressure can also be caused by cracked piston rings - have you been running high boost or standard?

Niz406 on here had similar problems I think but he's not around much now
