The key here is to tap the lower turbo drain pipe into the upper secured(bolted down) drain pipe.
Kind of hard to tap those drain pipes together from underneath with oil pan on, but it can be done....the two pipes need to completely join...
A thump or change in sound will indicate that they are joined, thats where you need some sort of sound change to tell you that it is joined....It's a lot easier...vs. jamming or pushing using force without tapping and hoping that they are joined..hope this makes sense....
Order a new turbo drain pipe, grommets and rings seals. Remove the oil pan, follow the instructions below and reinstall oil pan using a brand new oil pan gasket...
I found the link to my turbo drain pipe install instructions. Good luck
