is this anything I should be concerned with? oil on turbo.

So I'm getting ready to make my next purchase and looking for everything possible to sell.. Now that I'm an mhd user I decided to prepare the jb4 for sale/storage..when I was taking the connector apart the slide that locks the connector fell down into the bay where I came across this.

Before I go dropping cash on something other than my turbos, do I need to address this? Car boosts fine and doesn't use oil at an insane rate, about 1.5 liter per 7.5-8k. Stock cp had oil all in there but my new cp has been clean everytime I've had it off.

Thanks in advance.

Probably the turbo drain seal. I wouldn't worry about it, looks minor. If you're in there for other work, like a DP install, then maybe change it.

What I was hoping to hear and assumed myself.. I'll order the parts for in case I get inlets and have to climb under there again

your car would be a mosquito killing machine if there was this much oil inside the turbine exhaust area

Will need all the help I can get here on the river in Ohio *knocks on wood*.. But on a serious note, when the weather is warm and I drive somewhere,park the car, return an hour later and drive, the car will smoke at the first stop sign like a mfer then it's done.

I've read several threads on this kind of stuff but always get lost in the conversations.. Did we ever come up with a conclusion for this particular issue? Valve gasket? Turbo seal? Maybe an external pcv would help?
