E90 330d 06 reg
Noticed an oil leak and upon further checking I have found oil in the turbo air intake side, time for a new turbo?
Can only find oil leaking out of the intake seal that goes onto turbo, removed the pipe to find oil in the turbo

You do get oil in the shaft as it moves around the system.

Have you changed your crankcase breather?

No bud, seen quite a few posts with people thinking its that, read a post that said run car full dipstick and if oil comes out then breather blocked, mine didn't leak any oil.....dont know how true it is

I'd definitely look at changing it then. It's a 'lifelong' part that shouldn't be really.

My 06 320d was consuming loads of oil and leaking it out of the EGR. There was plenty in the turbo shaft like yours too.

I changed the vortex breather twice but didn't realise there's another membrane in the housing.

Ordered the complete part from BMW, think it's was £60 all in and it's absolutely fine now. I'm on just under 170k.

Is it puffing blue smoke when you put your foot down?

Do u think that could be causing the oil coming out? Had pipe off started car got to about 2 k revs and bit of oil started to come through

It wouldn't suprise me if it was that.

Whilst the loo roll style breathers used to cause no end of turbo failures due to starvation, a bad vortex breather will do completely the opposite.

If it's never been changed and you're on 150k it's a good place to start. Don't get a cheapo off eBay, get a genuine from BM.

The Garrett's on the 330d are genuinely solid.

Any recommended brand of breather?
Not sure if there's a BMW dealer on here selling parts? If there isn't ring your dealer and ask them for a price.

Just seen a Febi on eBay for £47. I'd say that's probably worth a shot.

Some just sell the clip in vortex with the oil seals. You want the complete plastic housing, vortex and oil seals / o rings.

Any play on the shaft?

My guess is when you get to the crankcase breather, it'll be very damp with oil in there. You'll enjoy the journey getting to it.

It should be damp, but you shouldn't have pools of oil like I did.

Quick update! Replaced the intake seal that goes onto the turbo and replaced the breather and seals so going to see how this goes !

You will always see oil around that spindle area, the engine breather feeds directly into the air intake hose from the air filter, if the car isn’t using excessive oil the don’t waste your money on a replacement turbo, i promise you will see oil around there within 100 miles of replacing the turbo. The oil isn’t coming through the turbo it’s being sucked onto the turbo.

The main problem was that it was dripping onto the driveway but I replaced the breather and the seal so hopefully it will not leak anymore, also there was no oil in the intercooler which I assume is a good sign

Looks excessive to me, had I have seen this post I would have first said what another chap did which was check for shaft play. The next thing would be the crankcase breather, a quick test is to unscrew the oil fill cap with your finger holding it down, release your finger and if theres excessive crankcase pressure you'll see the oil cap bouncing around, if all is well it will have little to no movement.

I tested this by first installing the loo-roll filter which had great results but started to clog rapidly and caused my oil cap to do this:


Then I removed the loo roll and installed the Vortex and


So if you've installed the loo roll be careful because if you have a lot of oil passing through it won't take much time to clog.

I did get the vortex breather asni read a lot of issues with the loo roll style, haven't had time to check the car from underneath as yet but when I do I will update with my findings, fingers crossed!
