Ls1 knocking.
So here's the situation 98 z28 ls1. 105k miles I noticed I was burning a little oil and so I replaces the pcv valve since it seemed to be leaking a bit. I broke the oil sending unit because that's my luck (I had the intake mani off because i wanted more room to fix it). I had to wait 4 days for the new unit and forgot to plug the port. Nothing should have fallen in there because once I pulled the sensor out the hood was shut and not opened until I put the new sensor in. I buttoned everything back up and started it up. Runs perfect except for 2 things. One I have higher than average oil pressure (65psi at idle). The real issue is its now knocking like a motherfker. It sounds to be coming from the bottom end near the center of the engine. I'm stumped as to what it is. Any ideas would be wonderful. I attached a video hopefully it works

Whoops noticed its in the wrong forum area hopefully someone can still help. I read it might be a bad oil pump that would make it knock but usually don't you loose pressure rather than it increase
