⚙️ Key Features

• Genuine Volvo Penta D16 inlet valve
• Later-generation cylinder-head application

🔌 Function

Controls charge-air entry into the cylinder and seals the combustion chamber during compression and combustion.

⚠️ Common Signs of Failure

• Low compression or poor starting
• Uneven cylinder contribution
• Burnt, pitted or recessed valve face
• Excessive stem or guide clearance
• Abnormal valve clearance, valvetrain noise or exhaust smoke

🛠️ Service Notes

• Keep valves in order and fit each one to the seat it is lapped to; a new valve must be lapped in until a continuous, even contact band shows right round
• Check the guide for wear before fitting a new valve — a good valve in a worn guide will not seat or seal for long
• Clean the deposits from the port and seat, wash every trace of lapping paste out of the head, and lubricate the stem with clean engine oil on assembly
• Fit new stem seals and check installed spring height and valve recess against the figures in the workshop manual for your engine
• Set the valve clearances on assembly and re-check them after the first running period, following the procedure for your engine
