Drain back for Pro-Vent

[MrMarty51]

I have the turbo drain back fitting from QuadStar Tuning.
I’m thinking before installing the flange/plate to the engine of drilling in the area of the red mark.

Taking a steel 1/2” NPT or even a 3/8” NPT pipe coupler and welding it on where I drilled.
In the future then, if a pro-Vent was ever needed there would be the fitting in place already for the drain back.
Is it Worth the effort is the question ? ? ? ?

Bad Idea. Good way to experience a diesel engine runaway when the oil flows backwards from the drain into the intake! The turbo flows a lot of oil. Little intake vacuum and you have a flooded Pro-Vent...

Take an example from Cummins who uses a separate drain into the block/oil pan from the oil separator on top of the valve cover.

I’m with WW on this.
Putting a fitting into the oil pan below the oil line is idea for the provent. Then do an actual hydraulic hose like heavy equipment would use so there is zero chance of failure.

Thank You for guiding Me along.
I’m still learning, even at 70++ years.
I’ll not do any changes to this drain back fitting.
I’ll give it a nice layer of right stuff and properly install it.
