Description Reviews MINI Cooper Turbo Oil line Banjo Bolts. These are the banjo bolt that hold the turbo oil line to the block and the top of the turbo. You can normally reuse these bolts, but sometimes they are clogged full of oil and it's just easier to replace them to make sure you have good oil flow. They require crush washers to make it work correctly; but they come with the new turbo oil line, so we didn't include them in this kit. Brand new MINI OEM parts. Note: Sold as a pair (two).
