Crank seal sump oil pump turbo oil return feed could be any of those buddy clean up the whole area start the car and sit underneath untill you see it may take a while until the oil thins out
Your oil rings don't show compression failure tho that's why you have compression rings as far as I'm aware anyway like I said before mate the only thing I could think of is oil rings did you check ya plugs dude??
I had a parking ticket from a private firm got about 3 letters then they just gave up they have no official grounds to charge you was there any kind of pay and display ???
Iev just had a rattle on the turbo aswell the bloke who had it before me messed about with the actuator trying to turn the boost up and loosens it that much the wastegate penny was rattling did my head in lol
U don't want any kinks dude everything needs to be perfect with fluids really even if it's a small amount a kink can still restrict the flow look at a hose pipe u don't need to link it much before the water starts to slow
Hmm well there's not many places to check for starvation to a turbo really return pipe from sump and from the bottom of the filter housing did you fit the turbo yourself
