Our 2015 T&C started smoking and would keep stalling out. Mechanic found the front bank with good compression. However on the rear bank when he pulled the valve cover he found a broken rocker arm that caused damage to the cam. He will not repair this as he states that there are metal shavings circulating through the motor and he would not guarantee the repair. I will get a second opinion as I am having the vehicle towed back to our house. Does anyone have any input on this situation. Should I think about replacing the motor. I still owe $9000 on the vehicle. Any advice would be greatly appreciated.
