Talked to dealer today, and they said they have had to remove the cylinder head of the engine becuase exhaust valves at low temperatures did not go bak and close due to exessive soot on valve stem, leaving the engine with no compression. the solution is to remove the EGR take off the pipe from exhaust to inlet and plug the holes. they have also changed some of the vales due to problems caused by exxessive soot. thats why i hope zetor goes common rail with little or no EGR. id rather have AD blue then engine failiure.
