Oil Spray Jet: Description and Operation

DESCRIPTION





The 1.4L engine has four engine blocked-mounted oil jets (1) installed to cool the underside of each piston. The oil jets are fed by the main oil gallery, and spray upward on the bottom of the pistons and cylinder walls. Each jet has a check valve which closes to maintain ample oil pressure at idle. All four oil jets are identical and are a press fit to the engine block.
