Yesterday I forgot to mention about what I found in the broken Oil pump
its a small pin which I have no idea where it came from
next detail I found is that the bolt on the Camshaft sprocket bank 2 was a little bit loose
check this !!!
there is some side to side play on the pin
then you can see on both side in the groove that same pin where it hit the camshaft sprocket
Compare the good one on the left and damaged on the right
