Piston Ring gaps are measured with the BHJ Torque Plates installed on the block.
After the honing process is complete, the block should be set aside to cool to room temperature. Lab
technicians should use a piston ring positioning tool to properly locate each top and second piston ring in each
respective bore ~1.0 inch from the deck of the block as indicated in Section 7 Sheet 4. (See Excerpt Below)
Record the piston ring gaps on the appropriate engine build data form and keep the rings in their respective
order for final engine assembly.
Wipe the cylinder bores and piston rings with solvent prior to performing ring gaps. Ensure the piston rings
are clean and all paint marks are removed.
Excerpt from Section 7 Sheet 4
Upon completion of all piston ring gap measurements, record the data in the appropriate forms and follow
standard laboratory cleaning procedures for cleaning the block using the Ultra Sonic Cleaner following
the manufacturer recommendations followed by a water rinse and spray with a 50/50 solution of degreasing
solvent and air drying.
Piston ring gap tolerence target ± 0.002 inch, the piston ring gap average for the block can be no more
than target ± 0.0015 inch.
