ahh... JB... a big breast methinks
I'm sure Yann is a proud Q4 owner.. so you can take your smut and sit on it

Could Yann be referring to the intercooler piping?
If there's oil on the outside of lots of pipes... has there maybe been oil spraying inside the engine bay some where? high pressure leak?
Or is the oil in the inside of these piping?
