ITEM DESCRIPTION
1 Piston cooling jets

Piston cooling jets, located in the cylinder block, provide piston and piston pin cooling and lubrication. Each piston cooling jet has two outlet nozzles which spray oil onto the underside of the two adjacent pistons, one from each cylinder bank. Each jet is located in a threaded hole between the pair of cylinders and is secured with a bolt. The piston cooling jets are supplied with pressurized engine oil from the oil pump via a drilling in the cylinder block.

Each jet sprays oil onto the inside of the piston. The oil coats the underside of the piston to help cool each piston crown. Additionally, oil lubricates the small end bearing and gudgeon pin.
