Crankshaft position sensor leak

    I have a 2001 PT Cruiser base model I am wondering if it common to have the crankshaft position sensor leak where it is attached to the engine? Mine seems to be and was considering removing it and replacing the o-ring. Anybody else done this?

    Probably engine oil. The CKP sensor is above the oil filter adapter which is a more common leak. So is the oil pan gasket.
    Because the sensor is mounted at the rear of the engine, oil can blow around and look like something else is leaking.
    If you are not sure of the leak source, it may help to degrease and rinse the area to do a visual leak location test.

    Agree with cleaning the area before replacing the O-ring, unless it has been removed recently it is extremely rare that it would leak.
