Hi im new here and looking for some help. I have a 2012 rr sport supercharged 5.0 that suddenly developed a rod knock i pulled the spark plugs in search of the culprit piston sure enough i found and confirmed that one has play , upon doing this i also found that the time must have jumped by a few teeth , my question is ,one how can both these failures occur at the same time and 2 is can i use an engine block from a non supercharged model thanks
