T1N Banjo Bolt, Turbo Oil Feed Line

This is the banjo bolt that you can see poking up between the two halves of the turbo. It's got a 13mm head on it and the oil feed line to the turbo is held in place by it.

They can break easily if overtightened. A torque wrench is highly recommended when replacing this bolt.  18N·m (160 lbs. in.)
