I took the fiesta to a Donnington track day a few weeks back and it highlighted that my breather system was inadequate as it was chucking loads of oil out of the breather filter whilst cornering.

The original system was only a spec R shiney and not up to the job, so I got a Bailey Escos catch tank modified with the right diameter connections to suit my car.

After loads of unrelated issues this week I finally got the car running with the new breather system on and a 19 row oil cooler and got it to Bedford for the RSOC track day at dinner time yesterday.

We did two laps and the brake servo hose popped of so we came in to secure it only to find when we opened the bonnet there was shit loads of oil al over the engine bay. Removed the filter of the "to atmosphere" breather pipe and the oil was coming from there.

I connected a pop bottle to this pipe and went out for another lap and came back in and it was full up (3/4's of a litre)

Have we got problems elsewhere? The car was not over filled with oil. We must have lost over 2.0l's over 3 laps.



This is the tank we have. The angled connecton on the bottom is piped up to return to the sump. The other bottom connection breaths to atmosphere. (where the oils coming from) The nearest connection on the top of the tank goes to the cam cover and the one behind to the back of the block. Is this connected correctly?

I would guess the tank probally holds a litre of oil so how the fook is it managing to fill this and still lob oil out?

Getting to the point of packing the car in tbh. Track days are meant to be fun and were just stressed out big time.

Yesterday cost us loads of grief, a couple of days off work, favours of various mates , fall outs with the other halfs and £500 in expense to do three laps!

Can anyone advise on why it could be breathing so heavy?
