I need some advice on my 2000 mustang GT a couple weeks ago it was running good I had no issues with it I parked it and when I went to start it up the next day the motor started making a noise on the top end out of nowhere since it was my only ride to work I had to keep driving it the noise kept getting louder and I noticed it was shooting oil out the exhaust. the oil pressure gauge kept shooting up and down and I tried putting more oil in it but that got nowhere so I parked it. I just pulled the engine out yesterday and stripped it I see nothing wrong the car only had 30,000 miles on it. all the cams were in good shape and tight as they should be. all the pistons and rings look brand new besides a little carbon, everything looks brand new I did notice some scrapings on the oil pump can anyone help me diagnose what it needs this is my first time doing a rebuild
