5. Clean inhibitor off new rings.
6. Measure end gap of rings in the cylinder and record in build sheet.
7. Fit rings with dots up
Note: End of oil ring expanded must be butted together. Piston rings orientated
with joins opposite and not in thrust line.
8. Fit pistons in cylinders. Oil Ring should only just enter so piston pin can be
