MINI & MOKE PCV FOR CLOSED CIRCUIT BREATHING [13H5191]
PRODUCT OVERVIEW
PCV valve for closed circuit engine breathing, commonly used on Mini, Moke and other classic British engine applications.
This valve has been very difficult to find for some time, but we now have them available.

WHY FIT A GOOD PCV VALVE?
A properly operating PCV valve helps control crankcase breathing and allows fumes to be drawn back through the engine rather than venting directly to atmosphere.
When working correctly, the valve should have no adverse effect on performance and may even help improve engine running by keeping the breather system functioning as intended.
IMPORTANT FITMENT NOTE
Please check your existing breather setup before ordering, as this valve is intended for closed circuit breathing systems.
The replaceable rubber diaphragm that is located inside the P.C.V. valve is available separately under part number [27H7758].
