Blowing air through the PCV system isn't enough. You need to take it off and clean all that sticky goop out, including the cam cover if its an ABY. Clean the flame trap or replace it.
It will take you some time to do all of this, the oil residue is thick & very sticky and takes some serious cleaning. Buy some bottle brushes and a load of carb cleaner to scrub and blow trough all the PCV pipes until it runs clean. Also take the intercooler off and flush that until it's clean. Clean all your intake pipework. FWIW I have no oil residue in my MAF to turbo hose, using stock breather system with freshly built bottom end - the system does work very effectively if in good order on a standard car.

Think that will be my next job!
I don't think the amount of oil in my maf to turbo hose is causing the severity of the smoke.
Could it be the turbo oil seal letting oil through it even though there's no oil residue upon taking the turbo off?
