Question about 2001 Chevrolet Cavalier
I am helping my mother in law fix her 2001 Chevy Cavalier. It started overheating and leaking water. I checked the car and the water came from the water pump so I replaced it. Now looking at the car because it started giving engine code p0300, I pulled the spark plugs and # 4 was full of oil. So I checked the oil and water mixed with the oil. Could this be just a bad head gasket? or would she need to replace the cylinder head? What should I check on the car? I'm helping her so she can keep repair cost low but I don't want to cause more damage.

In some cases I have seen blown intake manifold gaskets cause a milkshake in the crankcase inspect the lower intake gaskets coolant passages at the end of the cylinder heads for damage. I would suggest a compression test and a cylinder leak down test befor further tear down.

Have the DIS module checked and the coil pack for cyl 3. If either/both of those need replaced, have it done and have the codes cleared. Then see if it clears the others.
You may need a TPS (throttle position sensor) as well.

when run with a misfire, the cat will get loaded up with fuel, it takes awhile for it to burn out, and a code may set, on some occasions it ruins the converter, try clearing it and running it
