Turbo Inlet Oil Pooling - this much cause for concern?

[berns]

Car is in the shop right now getting a slew of upgrades, mostly drivetrain and suspension related. The poorly designed turbo inlet has been leaking oil everywhere and making a mess. Pull the inlet off the rear turbo and this dumped out.
I've seen a bit of oil in the inlets and IC piping of my previous turbo cars, but never this much.

Turbos are OEM stockers, replaced by BMW 20k ago. PCV system is stock, no catch can.
I haven't noticed any smoke from the exhaust, so I'm inclined to think the turbos themselves are fine, aside from the usual wastegate rattle that makes me hate driving this thing. Upgraded turbo(s) will come in time.

Car info: 103,000 miles, oil changed every 5k with BMW 5w-30, JB4 / MHD, pump 91 oct, Forge FMIC & CP, MS downpipes, Cobb Exhaust, BMS DCI.

Thoughts?

That's enough oil to think he seals on that turbo are about toast, especially if you have wastegate rattle. I had wastegate rattle when I bought mine with 58k miles, at 78k the front turbo seals blew out. Single turbo was my solution

That is probably the rear pipe that has the PCV from the valve cover. Normally people put the hose to a catch can. BMW uses the intake air from the turbo to suck it back in. It looks like it is pooling so just do a catch can instead and your mystery oil issue will disappear.

I would check the PCV first.

Thanks guys. Ordering the Rb PCV and BMS catch can. Will see if that makes things better. Unless you've got other recommendations?

Mine is leaking pretty bad even with OCC, oil consumption is a bit high too, havent got the rb pcv yet. 76k miles on my 135i, if seals were bad car would smoke wouldn't it?

yes, definitely would be smoking. I ordered the valve and OCC, will let you know how it goes.
