Im currently starting the process of diagnosing the issue(s) with the B7 I recently bought. The car has 185K with a uncertain maintenance history. The CEL for P0011 is on. The engine has good compression 160-180 psi on each cylinder. Im getting ready to get into this engine today, going to pull the HPFP and inspect the follower and the rear timing cover off to inspect the chain or tensioner. I have previously replaced the N205. I had the car out for about 20 miles of spirited driving a couple nights ago and now the engine is very noisy. At first I thought i had spun a bearing or bent a rod, but it doesnt sound like rod knock. Does this seem like a loose cam chain to anyone?
Cold start:
UPDATE 12/31/2020 - cold start after engine rebuild:
At idle:

At idle inside the car:
Just for comparison, here is what an old Ford motor in which a timing chain tensioner failed sounded like (I know these are two vastly different engine):
Here's how loose the chain one side was of that motor:
Any input welcome.
