I need to find a mechanic who'll do a complete valve seat jobt.(Triangle NC) I have spent 1400, two egr valves and clog egr valve, fuel injection servce, not sure if I have not lost a valve seat, but am not able to convince any mechanicto do the job preemptively. Perfect time to preeminently install new valve seats. Ineed to find a machinist. An ounce of prevention is equal to a pound of cure.
