    Ok... Procrastinator that I am I've done some work.
    I removed the belt, no difference.

    I pulled the valve cover and even though the timing chain had just been replaced the chain was a bit loose. So I put a new tensioner in the chain tightened right up but the noise is still there.

    I had it running and pulled coil packs to see if the noise went away, thinking like a rod bearing. I didn't notice a difference except running rough as expected.

    Here's a vid please see if you can help me out. I appreciate the input so far.

    Also to throw this out there, if anyone is willing to look at this and fix it I'd be glad to pay for your effort.
