Earlier I gave a simple answerer to a simple question. The OP needs to give a lot more detail on this subject. Was there any odd noises, or did it just happen out of the blue??
More than likely for on side to go dead the timing chain for that side has broke in half. And is nested somewhere in the front cover area, or laying in the bottom of the oil pan. Not sure if it really matters anymore as the OP has not been on here since he made the thread. I think we’re all just talking to each other.
