Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Cylinder Block: Disassembly
- INSTALL ENGINE TO ENGINE STAND
- REMOVE TIMING BELT AND PULLEYS (See REMOVAL )
- REMOVE CYLINDER HEAD (See REMOVAL )
- REMOVE WATER BYPASS PIPE
- Disconnect the wire clamp (for knock sensor 1,2) from the bracket of the water bypass pipe.
- Remove the bolt.
- Pull out the water bypass pipe from the water pump.
- Remove the O-ring from the water bypass pipe.
- REMOVE STARTER (See REMOVAL & INSTALLATION )
- REMOVE KNOCK SENSORS (See INSPECTION )
- DISCONNECT ENGINE WIRE FROM LH SIDE OF CYLINDER BLOCK
- Remove the 2 bolts and the engine wire cover from the LH side of the cylinder block.
- Remove the bolt, disconnect the bracket on the engine wire from the cylinder block.
- DISCONNECT ENGINE WIRE FROM RH SIDE OF CYLINDER BLOCK
Remove the 2 bolts, and disconnect the 2 brackets on the engine wire from the cylinder block.
- REMOVE OIL COOLER PIPE BRACKET FOR A/T
Remove the bolt and bracket.
- REMOVE ENGINE MOUNTING BRACKETS
Remove the 4 bolts and the mounting bracket. Remove the 2 mounting brackets
- REMOVE WATER PUMP (See REMOVAL )
- REMOVE NO. 2 OIL PAN (See REMOVAL )
- REMOVE OIL PAN BAFFLE PLATE
- REMOVE NO. 1 OIL PAN (See REMOVAL )
- REMOVE OIL STRAINER
- REMOVE OIL PUMP (See REMOVAL )
- REMOVE ENGINE COOLANT DRAIN UNIONS
Remove the 2 drain unions.
- REMOVE REAR OIL SEAL RETAINER
- Remove the 7 bolts.
- Using a screwdriver, ply off the oil seal retainer and the main bearing cap with a screwdriver.
- Remove the O-ring.
- CHECK CONNECTING ROD THRUST CLEARANCE
Using a dial indicator, measure the thrust clearance while moving the connecting rod back an a forth.
- Standard thrust clearance: 0.160 - 0.290 mm (0.0063 - 0.0138 in.)
- Maximum thrust clearance: 0.35 mm (0.0138 in.)
If the thrust clearance is greater than the maximum, replace the connecting rod assembly(s). If necessary, replace the crankshaft.
- Connecting rod thickness: 22.880 - 22.920 mm (0.9008 - 0.9024 in.)
- REMOVE CONNECTING ROD CAPS AND CHECK OIL CLEARANCE
- Check the matchmarks on the connecting rod and cap to ensure correct reassembly.
- Remove the 2 connecting rod cap bolts.
- Using the 2 removed connecting rod cap bolts, remove the connecting rod cap and the lower bearing by wiggling the connecting rod cap right and left.
HINT:
Keep the lower bearing inserted with the connecting rod cap.
- Clean the crank pin and the bearing.
- Check the crank pin and the bearing for pitting and scratches.
If the crank pin or the bearing is damaged, replace the bearings. If necessary, replace the crankshaft.
- Lay a strip of plastigage across the crank pin.
- Install the connecting rod cap with the 2 bolts. (See
REASSEMBLY )NOTE: Do not turn the crankshaft.
- Remove the 2 bolts, the connecting rod cap and the lower bearing. (See procedure ( b) and ( c) above)
- Measure the plastigage at its widest point.
- Standard oil clearance: 0.027 - 0.053 mm (0.0011 - 0.0021 in.)
- Maximum oil clearance: 0.065 mm (0.0026 in.)
If the oil clearance is greater than the maximum, replace the bearings. If necessary, replace the crankshaft.
HINT:
If using a standard bearing, replace it with the one having the same number. If the number of the bearing cannot be determined, sum up the numbers imprinted on the connecting rod cap and the crankshaft, then select the one with the same number as the total. There are 6 sizes of standard bearings, marked "2", "3", "4", "5", "6" and "7".

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
