For 1990-2009 cars only
- Measure the cylinder bores. Refer to Engine Block Cleaning and Inspection .
- Hone the cylinder bores with honing oil and a 400 grit stone in a 60 degree crosshatch pattern.
- Clean the cylinder block of all metal particles. Wash the cylinder bores with hot soapy water. Dry and oil immediately to prevent rusting.
- If scoring or scratches are still present in the cylinder bore after honing to the service limit, the cylinder must be bored, honed and fitted with oversize pistons. Some light vertical scoring or scratching is acceptable if it is not deep enough to catch your fingernail and does not run the full length of the bore.
Important: Use only a rigid type hone with a 400 grit or finer stone. Do not use stones that are worn or broken. If a cylinder bore is to be used again, hone the cylinder and measure the bore again. Only scored or scratched cylinder bores must be honed.
Important: Do not clean the block with solvent.
