Procedures
Cylinder Bore Honing1. Measure the cylinder bores. If the engine, block is to be reused, hone the cylinders and remeasure the bores. Only scored or scratched cylinder bores must be honed.
2. J35A7 engine: Remove the oil jets.
3. Hone the cylinder bores with honing oil and a fine (400 grit) stone in a 60 degree crosshatch pattern.
4. When honing is complete, thoroughly clean the engine block of all metal particles. Wash the cylinder bores with hot soapy water, then dry and oil them immediately to prevent rusting.
NOTE: Never use solvent, it will only redistribute the grit on the cylinder walls.
5. If scoring or scratches are still present in the cylinder bores after honing to the service limit, rebore the engine block. Some light vertical scoring and scratching is acceptable if it is not deep enough to catch your fingernail and does not run the full length of the bore.
6. J35A7 engine: Install the oil jets.
