Valve Spring - V8 is a cylinder head valve spring for the Rover 3.5L and 3.9L V8 petrol engine.

The valve spring seats between the cylinder head and the valve spring retainer, maintaining constant pressure on the inlet or exhaust valve to hold it closed against the valve seat and ensure positive closure after each cam lobe has actuated the valve. Correct spring rate is essential for reliable valve train operation across the full engine speed range.

Frequently asked questions

What does the V8 valve spring do?

The V8 valve spring seats between the cylinder head and the valve spring retainer, holding the inlet or exhaust valve closed against its seat after each cam lobe lifts it. It fits the Rover 3.5L, 3.9L, 4.0L and 4.6L V8 petrol engines used in the Defender, Discovery, Range Rover Classic and P38.

How many valve springs are needed for a full V8?

A Rover V8 has 16 valves, so a complete set needs 16 springs. They're typically replaced as a full set rather than singly, since matching spring pressure across all cylinders keeps valve train operation even. This part is sold individually, so order the quantity your job needs.

Why do valve springs fail on the Rover V8?

Valve springs weaken as the metal fatigues from constant cycling, reducing the pressure that holds the valve shut. Worn springs typically cause valve float at higher rpm, power loss, or a misfire. Replace them when refreshing the cylinder heads or if valve sealing is in doubt.
