Where is this from? Is that possible overfill oil and causing this? Since I just did oil change and workshop put 8 litre all in, check oil level is at the top...

 

Did they drain the tank and the engine? Maybe a spill putting it in?

 

I guess they didnt drain the main oil tank😵😵😵

How many litre overfilled if this is the case?

 

Less than one. There isn't much in there. After oil change, I usually put back 7 and check the oil to see how much further I need to go. The car only really needs 9 litres when you are beating the crap out of it. You won't break anything by being a little short for a day on the street.

 

Oh really, may I double confirm there is only less than one litre from the blue arrow tank?

 

the majority comes from the sump (blue), maybe a quart from the crank(green), the turbo reservoirs have maybe a cup...

 

No - From the engine crank case. Blue is a major gusher.

 

So I should overfilled a lot since the workshop didnt drain from the blue, damn....

 

Yeah! - If they didn't drain the blue, you could be in big trouble. Empty the whole thing (from the blue) and start over with about 6 litres (since you don't drain the filter this time). Then, start her up and see how it does. Once it warms up on the first drive, check it out and see what your level is like.

 

Take off the air inlets on your turbos, your intake is full of oil.

 

Will tow it back and do the same, hopefully drain and wash can resolve, I did drive about 40 miles before I figure it should be over filled.

 

++ on the inlets off, real easy to do. One hose clamp and pull the inlet back 1/4" or so and let the oil drain out.
