INSPECTION AND RECOMMENDED SERVICE ACTION

Engine Condition	Recommended Action
Any physical damage to one or more combustion chambers, cylinder walls, or valve contact with piston tops due to internal engine or timing issue. Excessive amount of metal debris found inside the crankcase and the valvetrain under the rocker cover(s). Inadequate oil pressure or contaminated oil supply with metal particles circulating throughout the engine, resulting in abnormal wear. Both the engine block and head(s) are warped due to overheating. Crankshaft does not rotate, seized. Vehicle has less than 500 miles on the odometer. (In this case, must install a NEW sub-engine assembly.)	REPLACE SUB-ENGINE ASSEMBLY (LONG BLOCK) NOTE: If a replacement long block assembly is not available, then assemble a long block using replacement short block and cylinder head(s) to complete the engine repair.

REPLACE SUB-ENGINE ASSEMBLY (LONG BLOCK)

NOTE: If a replacement long block assembly is not available, then assemble a long block using replacement short block and cylinder head(s) to complete the engine repair.

Engine Condition	Recommended Action
Engine oil consumption and/or excessive combustion blow by due to reduced seal between cylinder walls and piston rings. Minor structural issue of the cylinder block, resulting in slight leak or abnormal noise, with no other damage to the cylinder head(s).	REPLACE SHORT ENGINE ASSEMBLY (SHORT BLOCK) NOTE: For these conditions, do not replace the cylinder head(s).

NOTE:

Special Exceptions: If a required repair method is not possible due to prolonged parts backorders, discontinued parts, or technical matters that would prevent the completion of the repair, please contact the service region and technical assistance to determine the alternative repair route with prior approval.
Service Procedure: Refer to applicable Shop Manual for the required service procedures.
Engine Core Return Shipping: Follow all requirements to prepare the removed engine prior to core return shipping, including the complete draining of all fluids (engine oil and coolant).
