Low coolant light is on, radiator and overflow are full. Appears to be leaking oil on to the cat on the passenger side. Oil level is a little high, nothing other then oil on the stick. Makes a noise like i've got a REALLY bad u-joint when reving in park. Any thoughts?

 

If the oil is getting higher you have something like coolant gettting in there. If you drain the oil you will be able to check this. Coolant will settle on the bottom and will come out early when you drain it. I loosened the plug and the antifreeze dripped out almost instantly.

 

i just changed the oil last week and over filled it that teeny bit, it's not burning coolant. Nothing that I can think of could explain whats happening. especially since it appears to be leaking oil from somewhere.

 

I think this is some sort of defect with these type of coolant level sensors i see them trip the light all the time, most of the time taking the sensor out, cleaning it off and reinstalling it will fix it, but not always.
