94 lt1 oil pressure problems
About a month ago my car started making a chirping/ticking noise and had loss of power and low oil pressure. Found a bad lifter in cylinder 1, pulled the intake and checked a couple other lifters and found some small wear on them and saw I had some wear on the front of the cam. Put 4 new lifters in cylinder 1 and 2 and adjusted the valves and started it and it ran smooth as butter and oil pressure was good again. It's still running great, no noises and runs strong. I did this on Monday or Tuesday, and when I was sittin in a parking lot and my car heated up my oil pressure went almost to 0. When I first start it up it sits at almost 40, and when running normal temps it stays at about 20 or a little less. but now it's like when it warms up and sits there it wants to go close to 0 and at cruising/wide open throttle it doesn't go much past 20. what could this be? I'm new to this forumn.
