Scoupe L4-1468cc 1.5L SOHC VIN J MFI (1994)
NOTE:
Refer to appropriate Parts Catalogs for the applicable part numbers and descriptions of the related parts.
INSPECTION PROCEDURE AND GUIDELINES:
1. Inspect the incident engine using the ENGINE DIAGNOSIS WORKSHEET.
NOTE:
Refer to TSB 08-EM-004 (Remanufactured Engine Program) for details. Depending on the engine diagnosis, the results may not necessitate a short
or long block replacement to resolve the condition.
2. After completing the Engine Diagnosis Worksheet, determine the necessary action for repair.
3. If a short block replacement has been determined as the repair action with any of the following conditions, then ALWAYS replace the oil pump with
a new one:
^
Low or no oil pressure
^
Excessive metallic/foreign debris found inside the oil pan or oil pick-up screen
^
Continuous engine knocking noise (after isolating the accessory drive such as power steering, NC compressor, water pump, etc.)
^
Engine friction damage such as piston/cylinder wall scuffing, main/rod bearing/ journal scuffing, overly worn thrust bearing, or seizing of rotating
components
^
Engine overheat caused internal engine damage
4. If a short block replacement is not required and none of the existing conditions from Step 3 have been found, refer to the following inspection points
of the engine oil pump prior to reuse:
^
Turn the oil pump by hand (rotor/sprocket) to confirm it can be rotated freely without much resistance. Replace if internal binding damage is
observed.
^
Visually inspect the condition of the front main oil seal in the oil pump (for engines using a front case assembly oil pump) for wear, tear, or leaks.
Replace the front main oil seal if necessary to ensure a proper seal.
NOTE:
If the front main oil seal is found partially pushed out from the front case assembly, check if there is excessive crankshaft thrust endplay.
^
Visually inspect and clean the Oil (Pickup) Screen Assembly. Replace if damaged.
