Description Reviews This MINI Cooper Vacuum Pump will fit all gen 2 MINI Cooper S with the N14 engine. This includes the JCW engine that went into 2011 and 2012 MINIs that are not the N18. It's easy to tell by the large square PVC system on the top of the valve cover. We see these seize up with cars are run low on oil and it doesn't get enough oil to the vacuum pump to lubricate it. This is also the cause if your timing bolt broke off the end of the cam shaft and caused to motor to crash it's valves into the pistons. Also this is the only way to buy the nipple that the break booster attaches too if you break it off. This is the stock unit in another box so you save!
