I'm rather new here, but I own a 2000 Camaro V6. I bought it in December in near perfect condition. I have since put a little over 4000 miles on it (the odo reads 100025), and it wasnt until about 3 weeks ago when my oil pressure began to decline after running. I checked the dip stick to find that the oil was dirty. I quickly got the oil changed, and a couple of days later the oil pressure began to decline again. It starts up cold at around 80-90psi and after running for about an hour, it declines to about 55-61psi and not only that, when I hold the clutch in, the pressure declines to less around 30psi! Now it starts up at 60psi cold, and warms up to about 55psi, and when holding the clutch in, it reads about 10psi!How the old oil got dirty was because the oil filter was improperly installed, letting dirt get in the crevaces, ultimatly getting into the oil. Is my oil pump dying/dead, or is it something more serious? Many thanks, and Camaros for life!
