Engine Mechanical problem
1998 Cadillac Catera 6 cyl Two Wheel Drive Automatic 104000 miles
There is a tan, greasy substance in the oli filler tube. The oil does not appear to have water in it. It has been suggested that it has a blown head gasket, but with the oil having no water, I was wondering if there could be another problem. Someone said that there is some sort of plug that if you replace it, it will fix the problem. Any suggestions? Any help would be greatly appreciated.
