Headgasket failure?

[hussnainh8]

Hello

so i have a audi s5 3.0 tfsi and the coolant is mixing with the oil and the entire engine is full of this chocolate looking fluid.. i have drained out around 10 litres of the oil coolant mix from the sump. I have also removed the pcv and oil cooler and tried a liquid test on them where i fill them both with water and see if the water leaks out slowly from the oil passages but nothing leaks so i assume they are both okay. Cant do a proper test on them as dont have a way to pressurise them but im just wondering now should i replace them or is it more headgasket related?

i dont have any oil mixing in the coolant tank! Just coolant going in to the oil and sitting in the sump. Cylinder 6 spark plug had a very very light coat of wetness but it wasn't the coolant oil mixture on it so not sure what that could have been but wasn't anything too alarming.i also dont have oil in the coolant tank so can it be head gasket related or should i just replace the pcv and cooler?

thank you

It'll help Crasher identify the exact engine type and he'll possibly know if that type has any known issues / weakness
