Makes me wonder if the rod and or main caps are also in the wrong positions.yi you have at least 4 cam caps in the incorrect position.

It's not. I've seen brand new engines use a qt. every 500 miles.I guess it’s possible this new engine was just burning crazy amounts of oil. Doesn’t explain the oil on the steering rack. Still feel like 4 quarts in 5k street miles is insane.
From what I read, he got the shortblock already assembled. OP or his mechanic likely did the top end.Makes me wonder if the rod and or main caps are also in the wrong positions.
Yes, then he took it apart.From what I read, he got the shortblock already assembled.
Typical for a modified car. Lots of people revving even higher. Car has upgraded cams, upgraded springs and retainers, upgraded timing chains, and upgraded tensioners.8100rpm sound very high to revving this engine. No wonder it's making noises it's not supposed to.
Hard to tell from that photo but I think you are right. No idea how I got it wrong because I took reference photos when I took the original cams off… well that sucks. I wonder if I just accidentally swapped those around or if I did the other side wrong too.Fyi you have at least 4 cam caps in the incorrect position. Pass side, exhaust from front to back 1-5, intake front to back 6-10. Large cap is obviously 1 and 6 simultaneously. All of the cam caps are machined in the original locations and should not be swapped around. This could be your oiling issue.
EDIT - I circled the 9 position but meant to circle the 7 position. Number 7 is obscured in all the photos.
Need to see if any damage was done. Not sure what can be done if the head surface is damaged.Hard to tell from that photo but I think you are right.

Edit: checked my photos from when the motor was built and looks like I did that side wrong but did the other side correct. Wonder if I should swap the caps…
Assuming no damage has been done, how should I swap the cam caps?Need to see if any damage was done. Not sure what can be done if the head surface is damaged.
If the phaser is working the only thing left to do is a tear down inspection.Cranked the car with no valve cover and didn’t see anything obvious.
Is there no way for you to log and see what the commanded vs actual cam advances are? Sounds like it's a timing and/or VCT issue because at start up it follows one set of tables and then gradually transitions once you're within error tolerance of desired idle rpm.Put in the new vct solenoid and the codes went away as well as misfire on startup codes and random misfire.
Still knocking. I’ll post videos in a second. It’s really quiet when the car first starts but after a minute or so becomes pretty loud. When I first fired the car up I thought I fixed the issue but the noise slowly came back.
Anyone have suggestions before removing the engine? I am thinking compression test, borescope valves, and check oil for metal
