🔌 Function

The valve seals the combustion chamber against its seat in the cylinder head and opens on the camshaft's command to control gas flow through the cylinder. Correct sealing is essential for compression, combustion efficiency and controlled cylinder temperatures.

⚠️ Common Signs of Failure

• Loss of compression, hard starting or misfire on one cylinder
• Burnt, pitted or receded valve face causing poor seating and blow-by
• Excessive or noisy valve clearance that will not hold adjustment
• Bent or worn valve stem from over-revving or timing belt/chain failure
• Blue exhaust smoke and high oil consumption from worn stems and guides

🛠️ Service Notes

• Work clean — a valve is a precision component, and dirt or swarf carried in on the sealing faces is the commonest reason a new one fails early
• Fit new sealing rings, gaskets or washers wherever the original used them rather than reusing the old ones, and lubricate them lightly so they seat without rolling or nipping
• Check the seat, bore or housing the valve fits into for corrosion, scoring or distortion; a valve only seals as well as the face it beds on
• Tighten fixings and threaded connections to the figures and in the order given in the workshop manual for your engine — a valve body is easily distorted by overtightening
• After fitting, bleed or refill the system as required, then run the engine and check the valve for leaks and for correct operation before the boat is used
