Well, that's certainly worth a try.

Personally, the physics don't quite make sense (an inch or two of rise should not create a tremendous pressure differential) however others seem to feel that this can cause a serious problem, and I'll admit that I don't have much experience with poorly-installed oil drain lines, as I have never installed one poorly.

personal if i would have installed it, i wouldnt have ran it a crossed the front of the car to near the oil filter. i would have hit somewhere underneath the manifold. but i dont feel like pulling the oilpan off to fix the issue.

If by "fix the issue" you mean "install a fitting on the side of the oil pan beneath the turbo", there's no need to remove the oil pan for this.

I would posit that at least 90% of us (and probably much more) have installed this fitting in situ. The instructions for both Bell and FM turbos direct the installer to drill a hole in the pan and thread it for the return fitting without removing it from the engine, using a combination of grease and a post-machine flushing to remove shavings from the pan.

It's scary, and you will obviously end up with a few aluminum shavings left in the pan. But that's why you have a screen on the oil pickup tube and an oil filter just after the pump.

i know im capable of doing it i just dont enjoy having unnecessary holes in the pan so i would replace the entire thing. i know you can plug it but im not a huge fan of plugs more to go wrong.
