• Engine noise, misfire, reduced power or hydraulic malfunction
• Leakage around the valve or connection
• Severe adjoining-component damage if the part fails

🛠️ Service Notes

• Check the nozzle bore and the oil feed passage in the block are clear before fitting — gasket residue, sealant and carbon block these jets and a blocked jet lets piston temperature run away
• Handle the jet carefully and do not bend, straighten or reshape the nozzle tube to make it fit; a bent or cracked nozzle sprays in the wrong place and must be replaced, not corrected
• Fit the jet square on its locating dowel or spigot so it sits in the position the workshop manual for your engine shows, and tighten to the figure given there
• With the jet in place, bar the engine over by hand and check the nozzle clears the piston skirt and connecting rod through the full stroke
• Renew jets whenever pistons or liners are disturbed and the engine has run dirty or with extended oil changes, and confirm oil is delivered at each jet before the engine is loaded
