Also your proof of the tesioners being failed is similar to what I have found on these engines, and I been saying it all along.
Phaser noise can be caused by low oil pressure, and often dealers say these engines are junk to to "sludge and low oil pressure"
How can this engine have proper oil pressure when the timing chain tensioner seals dry up, blow out and **** oil.....
so many of you that have changed your phasers and still get phaser noise, I bet its your chain tensioners, DONT JUST CHANGE THE PHASERS AND TENSIONERS!!
These long chains stretch LOTS and the guides wear and can actually break.
If you have noise, take it apart and replace. Phasers, Chains, Guides, Tensioners... its like 350$ in aftermarket parts guys.... just do it!
Dont cheap out, you will have restored oil pressure, and the bad sounds that were timing related should be GONE!
Ive said this in a few posts before and will continue to say it every time i see a thread like this till its common knowlege.
Please while you have the valve covers off, check for pumped down lifters and back rockers or rollers too.
They also go bad.
Once again, good job on the repair, and congrats on doing it right!!
