Oil Jets
| 1 - Dual-Nozzle Oil Jets |
| 2 - Dual-Nozzle Oil Jets Bolt |
- Three dual-nozzle oil jets are bolted to the engine block underneath the main oil gallery. The jets connect with an oil-tight fit to the main gallery through lubrication passages. Each oil jet helps cool two opposite pistons. Proper oil jet alignment is important. Each nozzle is designed to alternatively spray oil through both cooling galleries within the piston. The oil spray is aimed at one of the cooling galleries as the piston approaches TDC. As the piston approaches BDC, the oil spray is aimed at the adjacent cooling gallery.
