The oil spray nozzle is installed directly into the cylinder block within the engine crankcase. Its primary function is to continuously spray a pressurized jet of engine oil onto the underside of the piston crown. In modern, high-output, small-displacement turbo engines (such as the TCe and DIG-T families), this provides critical cooling for the piston assembly. Proper nozzle operation prevents thermal expansion, piston burnout, and ring deformation, while also protecting the cylinder walls from scoring. Replacing the part is mandatory according to service protocols if, during an engine overhaul or block inspection, the nozzle orifice is found to be clogged with deposits or the internal spring-loaded valve is seized. The price listed on the website is per unit.
