The breather tank must be fitted as high as possible in the engine bay (higher than the rocker cover breather outlet) to prevent the oil catch can from filling up regularly. The pipework must constantly climb and avoid any low points that could fill up with oil, as this would prevent the oil droplets in suspension from returning to the sump.
Suitable for Zetec Black Top, Silver Top and ST170 engines.
Note: The kit must be used with a genuine Ford crankcase breather box (PCV) valve.
