Thanks for the response.

So data logging my car shows that bank two exhaust cam is not in sync with bank one... I replaced this phaser once when my car was on the dyno not making good power and we noticed the cam was off. Then again recently this week... From the last time the car saw the dyno until now has been about 3k trouble free miles. My car has not missed a beat since it was last tuned. However now it’s off and even after replacing the phaser it’s still not correct.

I called a buddy (who works on and builds these motors) tonight getting his opinion and he thinks at this point it could be a cam issue. I’m not sure what it is but just want it resolved.

My car does not sound like the one in the video at idle. At idle it really doesn’t sound bad (cams should be at 0). Just under load (when they are supposed to move) it starts to sound like a diesel. However the motor makes no knocking noise at all.
