Well with the help of my brother we pulled off the valve covers and timing cover to inspect the tension on the timing chain, both chains are so loose I can fit 8 fingers between chain and guides, odd thing I noticed is bank 1 of the motor is almost completely covered in sludge while bank 2 was surprisingly clean for 129k. We did it just to confirm if a new phaser and chains are in need of replacing. I have to do some digging and searching on how only half the motor is slugged up... I can honestly say I've never seen or heard of this before.
Also decided neither me nor my brother will do the new chains, I'll turn the keys over to ford master mechanic I know for this job, his specialty is fords 4.6 & 5.4 tritons.
Still haven't found the source to the p0340 & p0344 codes I'm having
