- While discussing the reasons for resurfacing a cylinder head; Technician A says it should be resurfaced to make it flat and very smooth so the head gasket can seal properly during engine assembly. Technician B says that it can be resurfaced to raise the compression. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardWhile discussing thread sealants and lubricants: Technician A says that antiseize compound is used where a bolt might become difficult to remove after a period of time.
