I emailed the chap that did my turbos and he was very happy for me to send it back down to him to check over, I'd assumed the large o-ring on the compressor housing had failed but he said it sounds like the scavenge system isn't working and that's forcing the oil out.
Leading evidence: 'Check over, i'd assumed the large o-ring' (no explicit attributable resolution; this is a reported action or suggestion).

While I was double checking other stuff I had the outlet pipe off and I noticed there was a small pool of oil sitting at the edge of the compressor housings outlet pipe, not a bit deal if the car had been running for months but by this point it had run for about 3 minutes.

So I'm just looking for a way of testing his theory?

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

After a bit of advice surrounding the oil scavenge system in the turbo.
After finally getting my car fired up (turbo replacement) I noticed the drivers side turbo was leaking oil from what I assumed to be the sump o-ring.
While I was double checking other stuff I had the outlet pipe off and I noticed there was a small pool of oil sitting at the edge of the compressor housings outlet pipe, not a bit deal if the car had been running for months but by this point it had run for about 3 minutes.

So I'm just looking for a way of testing his theory?
The oil pressure when the car was running was nice and high, the passenger side turbo has no leaks. They both have oil in the sump and in the lines.
What is the direction of flow? Is the oil sucked out of the bottom and returned to the tank? What's the upper line for? Is it just an over flow for the tank?
I can attach pictures if that would help anyone?
Thanks in advance
Oil is sucked in from the sumps by the dual scavenge pump on the end of the engine. There are three gears in there which form the two pumps. The oil/air is pumped from the scavenge pumps back to the tank.
The top line is a vent line, so that the scavenge pump isn't trying to create a vacuum in the turbo sump.

Hi
If this is of help, i have what sounds to have a similar problem on mine :?:
It's in for service at the moment and the tech advised that it's " bank 2 oil suction pump to pipe adaptor requires replacement"
I have attached a pic of mine in case it is of use :thumb:
It has created a mist or film over that area for a while and then i cleaned it last week to see if it was easier to spot where it is coming from
:thumb:
