Description Reviews MINI Crank Seal for all Gen 2 MINI Cooper or Cooper S 2007-2014 with the N12, N14, N16, & N18 Motors. Here at Detroit Tuned, we carry several brands you can choose from. They all work well and each brand has its own advantage. We have often found these seals leaking when doing timing chain kits here at the shop. As a result, we decided to add the seal from MINI to all of our timing chain kits. We are now offering these seals separately here to help stop any leaks. Two of the higher cost brands come with a more protective packaging, as well as being pre-formed to fit the crank (blue plastic). While the cheaper model works well, you will just need to take some extra time in order to fit the seal over the crank. Pick the one that is best for your budget or your piece of mind.
