Cylinder Block
- Measure cylinder bore out-of-round and taper. If either out-of-round or taper exceeds .002" (.05 mm), rebore cylinder for oversize pistons. If any cylinder exceeds oversize bore service limit, replace cylinder block. See CYLINDER BLOCK table under ENGINE SPECIFICATIONS .
- Using a feeler gauge and straightedge, measure cylinder block deck surface warpage. Service limit is .004" (.10 mm). If cylinder bore is okay, hone cylinder to obtain a 60-degree crosshatch pattern. After honing, wash cylinder bore using hot soapy water. Air-dry cylinder bore, and apply engine oil to prevent rusting.
