Question about 2000 Cadillac Catera
Valve sticking or a Ring has gone bad are the most likely causes. Try running a quart of GUNK engine cleaner and changing the oil, make sure you follow the directions or you will seriously damage your engine, or as an alternative you can try using a quart of Transmission fluid in the oil, warm the engine up and then change the oil and filter to clean your lifters and valves and build up.
