You either have had the wrong valve seals installed, they are physically missing, or the valves are incorrect (too loose in the guides/stem too thin). The rocker arm seals will not contribute to your issue. If it did not have the oil smoke before you took the head off, the issue is with whatever the machine shop did. Valve seals have to fit TIGHT, or oil will go down the valve stem into the intake.
Take the head back to the machine shop & tell them to fix it. For free.

Sounds like your injection pump timing is off, an injector is leaking or a bad seal on your IP.
VW dealers have a horrible reputation when it comes to TDI's. Check out the posts over at www.tdiclub.com Those guys are very knowledgeable - and the first thing they'll tell you is don't take it to a dealer.
You can probably find someone in your area that has a copy of Vag-Com (scantool software that vw uses) software that could look at your timing. It definitely sounds like your dealer was throwing parts at your car because they didn't know what your problem is. If I were you, I'd copy and paste your post from here over at www.tdiclub.com

Water in combustion chamber makes white smoke--suspect that the head gasket is leaking water into the chamber. If oil leaking around turbo, it may have a bad bearing and bad oil seal. Check waste gate valve and control.

Your thermostat may be staying closed, if the top coolant hose becomes hot after the engine running for a while, then thermostat is opening ok. Next check to see if the bottom hose going to the rad is getting warm. If its staying cold then you may have a problem with the water pump not circulating the water around the cooling system. If thats ok check the rad cap is sealing ok. when the engine gets up to normal engine temperture remove the reservoir top filling cap which has a rubber pipe going to the thermostat housing. with the engine running there should be no water coming down the pipe and exiting the filler cap. If there is it could be the rad cap not holding pressure which it would need to be replaced or the head gasket is leaking and pressurising the coolant system.. hope this helps you..
