Hey everyone! I have a 06 Jeep commander 5.7 hemi. The other day, drove 15 miles, stopped, turned the vehicle off, came back 2 minutes later and when I turned the key, had a problem starting, almost like it didn’t want to turn over. I finally got it to turn over and it was such a ruff, hellacious rattle when rpms were up... let foot off gas and it stauled ... tried again, same thing.. never wanted to keep running and the same horrible sound. We are very good at changing oil, checking fluids.. keeping it in tip top shape. Had NO clue, not even a hint this was gonna happen... anyone out there know what it could be? We took it to a garage and they seem to think the timing chain broke or bad lifters? How would I know that with out tearing it apart? What should I check first? Sorry just so upsetting when you keep nice things and this happens..
