| 1 | Piston cooling oil jets |
Piston cooling oil jets, located in the cylinder block, provide piston and piston pin cooling and lubrication. Each piston cooling oil jet has 2 outlet nozzles which spray oil onto the underside of the 2 adjacent pistons, 1 from each cylinder bank. Each jet is located in a threaded hole between the pair of cylinders and is secured with a bolt. The jets are supplied with pressurized engine oil from the oil pump via a drilling in the cylinder block.
Each jet sprays engine oil onto the inside of the piston. The engine oil coats the underside of the piston to help cool each piston crown. Additionally, the engine oil lubricates the small end bearing and gudgeon pin.
