Ok guys got another question....the car is a gttdi 140 bhp 05 plate...got underneath the car the other day and noticed this brown oily sludge. It was down the back of the block on the engine tray and on the exhaust...the bit near the turbo. I had a look at the turbo and it was clean, but couldnt see where it was coming from??? has anyone seen this before??? i did a bit of research and on one forum it was mentioned about an erg pipe splitting? any advice is welcome ...cheers
