I get home from work today & hear a noise under the hood of the XF, also see what looks like oil smoke. Pop the hood & there is oil all over the front of the engine compartment, but can't see where it is coming from. I turn the car on & see the water pump pulley is wabbling real bad & making the noise that I heard. I assume this means I need a new water pump, but would a bad water pump throw oil all over the place?
