Oil in intake of turbo

Hi guys
I changed my oil last week including a new filter. I over filled it so today I tried to take some out by unscrewing the oil filter housing. No oil came out. I checked the filter, oil has been in there as filter was oily.

I took the air intake off to make it easier to get at the oil filter housing and noticed a pool of oil inside the turbo intake side. Is this because I over filled? The tappet cover breather hose to air inlet housing also had drops of oil coming out. I am going to fit a catch tank tomorrow.

Any tips appreciated.
Cheers Jack

if the engine is overfilled it will blow oil into the intake.
