WTF? Is this a problem with my turbo?

So, I was doing a little work under the hood of my car, checking my IC piping and such, and noticed this on my turbo:

It's a hole in the casting right by the oil feed. Is this a problem? Would this explain my intermittent oil leak from my turbo?

It looks dry, has there been any oil coming from the hole?

Possibly. That hole is where a drill has gone to far. The GT40 series turbos use a backplate that is held on by screws UNDER the compressor wheel.

That hole you see is from one of those screws. It may be possible that oil is seeping past that screw and out....

I don't know. The turbo spews a ton of oil about 5 minutes after I cold start it, and I'm always in traffic when it happens, and it stops before I can get somewhere to pull off, so I'm not sure if it's leaking from there. It's leaking from somewhere, I just don't know where.

I emailed precision about it, I'm just waiting to hear from them.

look like the bolts you used may have been a tad to long

is that SS hose always touching the hot side of the turbo? I see a leak followed by a fire shortly.

i'm more concerned that the oil feed looks to be -6....

Good call DRJ. If it is, there's your leak...

it's a -4, I just zoomed in really far. and no, it's not touching the hot side. I just pushed it out of the way for the picture.
