This 2007 Bentley GTC came in to diagnose a rough running condition and a CEL issue. The DTCs I found were related to engine misfires on multiple cylinders. After removing the upper intake and coil packs I found oil leaking down several spark plug tubes which was causing the misfire. Obviously the customer wanted the repair performed and also chose to have the major 4 yr. service done at this time. We also updated the coilpacks due to a revision in part number. Here are some pictures of the engine with valve covers off. Not many people get to see this so I thought I would share....
