Again it sounds just a bent rod but they are all good. Any help or ideas would be greatly appreciated. Thanks

A colasped lifter would let the push rod become loose on the tappet and cause a loose tappet sound.
Can you by chance do a video with sound and post it here so we can listen to it and possibly help you diagnose problem.
How did the engine run when this occured?? Missing???
Have you checked the camshaft sensor and snycronizer condition as it is located on the front of the engine (passenger side) middle.
Is the check engine light on??? if so what are the codes???
Did the idiot light for oil pressure come on??
