Hi all. A mate of mines just bought a mk2 fiesta running a 2litre turbo. He's not sure if its a zetec turbo or a ZVH but says oils being forced from the catch tank through the filter and also into the exhaust? Any ideas? He's ony just got it and I'm gunna go up and have a look tonight but thought I'd ask on here as I know its full of people who certainly know there stuff. Thanks.
