6-10 Engine Mechanical - 5.7L Engine 2001 Marine/Industrial Checks Action Engine Performance diagnosis procedures are covered in Engine Controls and should be consulted for diagnosis of any Drivability, Emissions or Malfunctioning Indicator Lamp (MIL) concerns. The following diagnosis covers common concerns and possible causes. When the proper diagnosis is made, the concern should be corrected by adjustment, repair or replacement as required. Refer to the appropriate section of the service manual for each specific procedure. This diagnostic table will assist in engine misfire diagnosis due to a mechanical concern such as a faulty engine camshaft, worn or damaged bearings or bent valve pushrod. Thsi table will not isolate a crossed fuel injector wire, faulty fuel injector or any other drivability component failure that may cause a misfire. The Powertrain On-Board Diagnostic System checks must be performed first. When using this table to make a Base Engine Misfire diagnosis, begin with the preliminary information below and then proceed to the specific category. Preliminary 1. Perform DTC P0300 before proceeding with Base Engine Misfire Diagnosis information. DTC P0300 will assist in determining which cylinder or cylinders are misfiring. 2. Perform a visual inspection of the following: A loose or improperly isnstalled engine flywheel or crankshaft balancer Worn, damaged or misaligned accessory drive system components 3. Listen to the engine for any abnormal internal engine noises. 4. Inspect the engine for acceptable oil pressure. 5. Verify if the engine has excessive oil consumption. 6. Verify if the engine has excessive coolant consumption. 7. Perform a compression test on the engine. Intake Manifold Leaks An intake manifold that has a vacuum leak may cause a misfire. Inspect for the following: Improperly installed or damaged vacuum hoses Faulty or improperly installed lower intake manifold and/or gaskets Cracked or damaged lower intake manifold Improperly installed MAP sensor The sealing grommet of the MAP sensor should not be torn or damaged Improperly installed throttle body or damaged gasket Warped intake manifold Warped or damaged cylinder head sealing surface Coolant Consumption Coolant consumption may or may not cause the engine to overheat. Inspect for the following: External coolant leaks Faulty cylinder head gasket Warped cylinder head Cracked cylinder head Damaged engine block Oil Consumption Oil consumption may or may not cause the engine to misfire. 1. Remove the spark plugs and inspect for an oil fouled spark plug. 2. Perform a cylinder compression test. 3. If the compression test indicates worn valves or valve guides, inspect the following: Worn, brittle or improperly installed valve stem oil seals Worn valve guides Worn valve stems Worn or burnt valves or valve seats 4. If the compression test indicates worn or damaged piston rings, inspect the following: Broken or improperly seated piston rings Excessive piston ring end gap Excessive cylinder bore wear or taper Cylinder damage Piston damage Diagnostic Information and Procedures Base Engine Misfire Diagnosis
