Ok, Got a '95 Contour, 114K miles, cats were plugged but seemed to have unclogged. Now the problem. My oil consumption is way up--about a quart or two per tank O gas. When I add oil, I notice white smoke slowly coming out of the oil fill or dipstick when I check the oil. I'm sure driving the car with plugged pre-cats did some damage but now that the car seems unclogged on it's own doing.....what da ya think is causing all of this? Smoke seems to come out the tail pipe. No coolant loss....CEL always comes on and off so i put no stake in that thing. I was losing about a quart of oil every 1000 miles prior to cooking my pre-cats from crossing my spark plug wires when changing the plugs. Ideas?????
