Cylinder Block
- Using a straightedge and feeler gauge, check for cylinder block deck surface warpage. Machine cylinder block if warpage exceeds specification. See CYLINDER BLOCK table under ENGINE SPECIFICATIONS.CAUTION: Do not machine more than .010" (.25 mm) of material from original cylinder block head surface.
- Check cylinder bore diameter, out-of-round, taper and scoring. Cylinder bore is measured 1/2" below cylinder block deck and 1/2" above piston when at bottom of cylinder bore. Cylinder block must be bored if not within specification. See CYLINDER BLOCK table under ENGINE SPECIFICATIONS.
CAUTION:
If cylinder block is bored, ensure main bearing caps are installed and bolts are tightened to specification. This prevents main bearing bores from being distorted when boring cylinder block.
