Cylinder Bore Cleaning and Inspection

CLEANING
After any cylinder bore service operation, such as honing or Reglazing, clean bores with soap or detergent and water. Then thoroughly rinse the bores with clean water to remove the soap or detergent, and wipe the bores dry with a clean, lint-free cloth. Finally, wipe the bores with a clean cloth dipped in clean engine oil XO-1OW30-QSP or -DSP or equivalent meeting Ford specification WSS-M2C153-G.

CAUTION: If these procedures are not followed, rusting of the cylinder bores may occur.

INSPECTION
After the cylinder block has been thoroughly cleaned, check it for cracks. Invisible cracks may be detected by coating the suspected area with a mixture of 25 percent kerosene and 75 percent light engine oil. Wipe the part dry and immediately apply a coating of zinc oxide dissolved in wood alcohol. Do not use rubbing alcohol as a substitute. If cracks are present, the coating will become discolored at the damaged area. Replace the cylinder block if it is cracked.
