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.

Let's move this out of the Lounge, to "LT1 Based Engine Tech".... better forum for tech help.

Before my head gaskets went for about 80 miles of running the oil pressure dropped to 0.
