🔌 Function

Sprays a jet of oil onto the underside of the piston to carry heat away from the crown and ring belt.

⚠️ Common Signs of Failure

• Piston crown or ring belt discoloured, cracked or burnt
• Jet blocked with sludge or debris
• Jet bent so the spray misses the piston
• Oil pressure slightly low with a jet leaking at its seat
• Rings found stuck or coked in their grooves

🛠️ Service Notes

• Check the engine serial is 2061139523 or later before ordering
• Prove the jet is clear and correctly aimed on assembly, since a misdirected jet leaves the piston uncooled
• Renew the sealing washer or o-ring at the jet mounting
