Perhaps just a rough day. Enjoy a beer15 Minutes they said, one hand tied behind my back he said. Wow what an adventure. First all kinds of tubes and wires to detach, then the coil wires would not come off after being unlocked. No problem you can remove the coils with them still attached. Problem, front coil drivers side, disconnected the breather tube from the cam cover and left it connected to the turbo cold air tube. Pulled the coil and hand caught the breather tube and broke the nipple at its base. No fixing. Plug change just cost me another $150 and 2 days down time. Found a lot of oil in the cold air tube and in front of the turbo. We are talking standing oil.
