Of note: In the original post he mentioned the cam phasers had been replaced already, perhaps this could be ruled out. .....unless there has been enough contamination of the oil to plug them up, or low oil pressure to begin with?
The sound he hears certainly seems consistent with a plugged cat or restricted fuel flow, but some of this is replaced also. What are we all overlooking?
