My mk 5 1.9tdi golf is blowing some oil at the filler cap seems

Resolved Question:

My mk 5 1.9tdi golf is blowing some oil at the filler cap seems to be a lot of crankcase pressure.theres a whistle or whine aswell taking off and slowing down .the car was v well serviced and looked after 144 on the clock but I don't think it rings or a turbo problem I think it may b a PVC valve .just wondering is the mk 5 prone to this problem

Hello

I'd agree that this sounds ike an issue with the crankcase ventilation system

I'd 1st look at replacing the small PCV thats on the cam cover and has a pipe attached to it and that pipe runs back to the inlet pipe on the turbo
