Well I have done the turbo drain tube twice and never done the B2 valve.
It is a very doable job as long as you set yourself up for any potential problem, then you will be ready and the job can be done.
Buy a lower oil pan gagket JUST IN CASE. if the tube is apart you can't run down to the dealer to get the gasket.
As posted you remove the tubes by pushing them towards the front right corner of the car once the upper bolts have been removed.
To remove them is a bit of a pain but patients will get you results.
IIRC one bolt is removed with a long (18" and universal) extension from below the engine and slightly behind the turbo. the other IIRC was with a stubby ratchet and a 2-3 inch extension on the universal. Once the bolts are removed, move the tubes joint towards the front right corner of the car. To make it easier I unbolted the AC hose from the engine block, One 17mm, I think, bolt and the hose moves over 1-2 inches. Once the tube seperates then drop the upper tube and then pull upward on the lower tube. remove the lower tube rubber gasket and install a new one lubricated with oil.
Now the short cuts. Use some permatex "high tack" gasket sealant to attach the new turbo gasket to the upper tube. Cover all orings with oil and install both tubes by placing the separation part at the front right corner of the car, mate the tubes while moving them onto position. I do remember rotating the upper tube while doing this so it cleared various engine parts.
Once in position a magnetic socket helper and a spring universal helps install the screws. They can be done by hand if you hand is not to big. I'm 6' 2" and have large hands, I can do it by hand.
Once you get the screws started then tighten them as you did while remoing them.
While dong this my car was on jack stands and I had a creaper to get around under the car.
Yes it is a PITA sort of job but very doable.
