    Yes I broke it trying to pry the valve cover off.
    New cover is on without any problems but I need to replace this sensor.

    It's that one right next to the timing chain with a ground wire connected to the top bolt. It has a 4 pin connector that broke.

    On attempting to remove it part of The housing broke off inside. I was able to get the core out. Am I going to have to take the valve cover back off.
