I know we keep beating this to death!
But your CCV hose should be connected to the turbo inlet to pull a negative vacuum on the engine crankcase. If was designed by the engineers to do this!
Some on this forum have reported either a blown or leaking oil seals when they ran without the CCV connected to the turbo inlet boot (EHM)
Reminder; the vacuum pump on this engine discharges into the engine crankcase internally adding to the internal pressure along with whatever blow by you have form the piston rings and all this add greatly to the flow loading of the CCV system externally.
See this for plenty of reading on all the reasons NOT to run the CCV to atmosphere:>
viewtopic.php?f=5&t=80491Just as a second thought, are you sure there is no obstruction in the turbo oil drain line or where the drain line connects into the block?
The drain from the turbo should basically be an open drain back into the block with no restrictions.
After two turbos leaking, I would be darn sure that the drain has no issues and I would connect that CCV back to the turbo inlet boot to ensure the suction from the turbo is pulling a negative vacuum on the crankcase when the turbo spools up. (Same time as the oil pressure would increase due to increased RPM's.)
Keep us posted!
NOTE: Many install a Provent coalescing filter to filter and catch oily liquids to remove them out of the CCV vapors before they enter the turbo inlet pipe.
