I need to change my oil pump on my 98 plymouth Neon and need the service manual to see how to do it exactly...Thank You.. Vince Farmer

Because I believe the oil pump is bad. I had driven my car one night to a friends house and brought the car back home. And parked it over night, got up the next morning and started the car and the Rods were knocking badly, so I shut the car off and checked the oil level and there was no oil on the dipstick. And then I noticed on the ground all of the oil had drained out of the oil pan. So I took the old oil pan off and looked at it and it had a crack in the pan that had been there for some time, but the car had never leaked not even a drop of oil. But replaced the oil pan and put new oil in the car. And started the car up and everything was cool, and quiet. And I drove the car, brought it back home parked it and went to go to Lowes later, and started the car up again and the valves were rattling again, so I checked the oil and it was fine on max. And I went ahead and drove the car to Lowes and back and had my Dad listen to it and he said your car is screwed and I said yes I know. But later that night I wanted to test drive the car again, because for one I was bewildered that the car was quiet when I first started it and was making so much noise now. So I drove the car around the block again, and I noticed as long as I was keeping speed up my oil light stayed off, but when I came to a stop sign or stop light, my oil light wanted to come on. Which tells me that the oil pump is probably bad. Thanks for your help. Vince Farmer
