    I am currently trying to sell my '07 e83. A perspective buyer took the vehicle to an independent shop which found an oil leak onto the Eccentric Shaft Sensor plug. Repairs require replacement and possibly replacement of head bolts under the valve cover.
    They indicated it was not uncommon, but I've not seen any mention of this. Does anyone have any back ground on this?

    Yes a leaking eccentric shaft sensor is common for the N52. Replacement of the sensor requires removal of the valve cover and then just 3 10mm bolts hold it to the eccentric shaft magnetic wheel. Depending on how bad the oil leak is you need to check the DME to make sure no oil made its way there through the wiring. If so will have to replace the wiring harness and DME. BMW has a SIB on this issue.
