New user to the forum - Hi! I recently changed the air filter and found some oil collecting in the turbo intake pipe which connects to the air filter.

Not sure what it could be? No smoke on boost or cruising and no signs of major oil use. Car still does run an oil metering pump.

Also what are these little holes on each side of the pipe / what do they connect to? (Just finding it a bit strange that only a small amount of oil collects at the bottom of the intake pipe and not further towards the turbo impeller).

Any help suggestions would be greatly appreciated!

ok clearly I didn't attach the picture ... give me a moment ...

 

Obviously it's a single turbo, what hoses are connected to that intake pipe?

It's possible one is going to the oil fill neck for PCV, that's most likely the source of the oil. You can run a vented catch can to collect the mess.
