Cylinder head gasket selection
CAUTION: New cylinder head gasket
should be same thickness as the original.
If, however, cylinder head, pistons or
crankshaft have been replaced, it will be
necessary to check piston stand proud in order
to determine the correct thickness of gasket.
1. Position a magnetic base DTI to cylinder block
top face adjacent to number 1 cylinder bore.
2. Position stylus of gauge to cylinder block top
face on edge of number 1 cylinder bore; zero
gauge.
3. Rotate crankshaft in a clockwise direction until
numbers 1 and 4 pistons are at TDC.
4. Position stylus of DTI gauge near edge of
piston crown, measure and record number 1
piston stand proud. Measurement must be
taken at front and rear of piston and highest
protrusion figure recorded.
5. Repeat above procedures for remaining
pistons.
