INSPECTION
1. CLEAN CYLINDER BLOCK
(a) Remove the gasket material.
Using a gasket scraper, remove all the gasket material
from the top surface of the cylinder block.
(b) Clean the cylinder block.
Using a soft brush and solvent, thoroughly clean the cylin-
der block.
2. INSPECT CYLINDER BLOCK
(a) Inspect for flatness.
Using a precision straight edge and feeler gauge, mea-
sure the surfaces contacting the cylinder head gasket for
warpage.
Maximum warpage: 0.05 mm (0.0020 in.)
If warpage is greater than maximum, replace the cylinder block.
(b) Visually check the cylinder for vertical scratches.
If deep scratches are present, rebore all the 4 cylinders and re-
place all the 4 pistons. (See page EM±104) If necessary, re-
place the cylinder block.
(c) Inspect the cylinder bore diameter.
HINT:
There are 3 sizes of the standard cylinder bore diameter,
marked º1º, º2º and º3º accordingly. The mark is stamped on the
top of the cylinder block.

If the end gap is greater than maximum, replace the piston ring.
If the end gap is greater than maximum, even with a new piston
ring, rebore all the 4 cylinders (see page EM±104) or replace

pin into the piston pin hole with your thumb.

ing rod alignment.
