For 1990-2009 cars only
- Clean the sealing material from the gasket mating surfaces.
- Clean the engine block and lower crankcase in a cleaning tank with solvent appropriate for aluminum.
- Flush the engine block with clean water or steam.
- Clean the oil passages.
- Clean the blind holes.
- Spray the cylinder bores and the machined surfaces with engine oil.
- Inspect the threaded holes. Clean the threaded holes with a rifle brush. If necessary, drill out the holes and install thread inserts. Refer to Thread Repair.
- Use a straight edge and a feeler gage to check the deck surface for flatness. Carefully machine minor irregularities. Replace the block if more than 0.254 mm (0.010 in) must be removed.
- Inspect the oil pan rail for nicks. Inspect the front cover attaching area for nicks. Use a flat mill file to remove any nicks.
- Clean the sealing material from the gasket mating surfaces on the lower crankcase engine block side.
- Clean the sealing material from the gasket mating surfaces on the lower crankcase oil pan side.
- Inspect the mating surfaces of the transmission face.
- Use the following procedure in order to measure the engine block flange runout at the mounting bolt hole bosses:
- Inspect the crankshaft main bearing bores. Use a bore gage to measure the bearing bore concentricity and alignment.
- Replace the engine block and bed plate if the crankshaft bearing bores are out of specification.
- Inspect the cylinder bores. Inspect for the following items:
Important: Do not attempt to machine the lower crankcase to engine block surfaces.
Notice: A broken flywheel may result if the transmission case mating surface is not flat.
| 13.1. | Temporarily install the crankshaft. Measure the crankshaft flange runout. |
| 13.2. | Hold the gage plate flat against the crankshaft flange. |
| 13.3. | Place the dial indicator stem on the transmission mounting bolt hole boss. Set the indicator to 0. |
| 13.4. | Record the readings obtained from all of the bolt hole bosses. The measurements should not vary more than 0.203 mm (0.008 in). |
| 13.5. | Recheck the crankshaft flange runout if the readings vary more than 0.203 mm (0.008 in). |
