Turbo oil feed restrictor question

[RETed]

Before it gets that messy, we should try and confirm that this is the case?

How is your emissions plumbed in right now?
I'm assuming the stock emissions have been removed or modified by now?
I'm talking specifically about the "PCV" system.

As a quick-n-dirty test, remove the oil filler cap and see if the problem changes?
If the smoke disappears, you have too much positive pressure in the "crankcase".

As for your oil return system...
I'm assuming you're using -10 fittings and adapters?
Normally, a -10 line is fine, but it's the more restrictive fittings and adapters that neck the system down that causes a restriction.
As a rule, I try and fit a minimum -12 set-up for any oil return system.
Else, the stock system that uses flanged / "barbed" fittings is usually superior in terms of cross-section area for the oil drain due to this fact...
