Check the oil on the dipstick. Is there white, milky, "goop" on it? If so it's a blown head gasket. The 3.1 liter V6s are notorious for that. If you have the 3.8 liter (optional on SE models) the intake manifold gasket has probably failed. Since you're hearing a knocking sound I believe coolant has leaked into the crankcase, contaminated the oil and damaged the bearings. Given the age of the vehicle and mileage it's probably not worth fixing. Unless you can get a good used engine cheap. But even then you won't know if these gasket issues have been addressed. It's a big gamble on a 17 year old car. HTH. -Jim
