Hello all ive got a 51" fiesta zetec S mk5 all std with 72k on the clock

Now the problem im having is its pushing oil out the breather pipe that goes to airbox and filling with the oil then ending up in the iner wing ect

Now im guessing its a prob with the breather system as I have done comp test & all very good, I have also done the roll down hill then come on the throttle and there is no smoke coming out the rear at all either

So whats the best places to start looking and trying ?? any common probs that these have at all?

cheers for all help guys & girls
