I was also going to post my own message about high oil consumption, but I'm new and it took me a bit to register. The car sat parked since last fall with no oil problems, but it has developed a habit of using about a quart a day (I drive 200 miles a day) this year. It has fouled out at least one plug also. I had the head gasket redone last spring and only drove about 2,000 miles for all of last year with no problems. I get a terrible "bucking" when I accelerate and after I have the cruise on for 50 miles, I can fog a city block if I punch it from a dead stop. But then the car will act fine for awhile after that. The oil light comes on intermittenly and I never let it go below a quart low. The oil is real black, even after 100 miles after an oil change. I have tried a PCV valve, but that really didn't make much difference. Am I looking at a valve job too? Thanks for any replies.
