Use vegetable oil to lubricate the new o-rings. Do not soak the new o-rings in engine oil.

Install the o-rings into the groove of the piston cooling nozzle.

CAUTION  Do not use the capscrew to pull the nozzle into the cylinder block. Nozzles and o-ring damage or external oil leaks can result.

Install the nozzles into the cylinder block.

NOTE: Make sure the oil passage opening in the piston cooling nozzle is pointing up toward the piston.

Install the capscrews.

Tighten the Nyloc capscrews.
