⚙️ Key Features

• Approximately 48 mm valve-head diameter
• Approximately 9 mm stem diameter
• Heat-treated inlet-valve construction matched to D5/D7 cylinder heads
• Precision face seals against the specified inlet-valve seat
• Keeper grooves, stem and tip match the documented spring and rocker arrangement
• Valve recession, protrusion and guide clearance must be checked during overhaul

🔌 Function

Opens to admit charge air into the cylinder and closes against the seat to seal compression and combustion pressure.

⚠️ Common Signs of Failure

• Compression falls in the affected cylinder
• The engine becomes difficult to start or loses power
• The valve face, margin or stem is burnt, bent or worn
• Valve clearance changes repeatedly
• Air leakage is detected during cylinder-head testing

🛠️ 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
