3.6L v6 LT1
I am experiencing misfires on cylinders three and five. I have replaced spark plugs, swapped cylinder 2,4,6 ignition coils with cylinders 1,3,5 coils. Also all cylinders passed compression tests. I proceeded to take off the oil pan to check for a possible cracked piston and I found what appears to be timing chain tensioner guide pieces. The vehicle was still running (obviously not running now as the valve covers are off and oil pan is off), could the bank one misfires be a result of a timing chain issue? Thanks!
