Klepveer - V8 is een klepveer voor de cilinderkop voor de Rover 3.5L en 3.9L V8 benzinemotor.

De klepveer zit tussen de cilinderkop en de klepveerschotel en handhaaft constante druk op de inlaat- of uitlaatklep om deze gesloten te houden tegen de klepzitting en om een positieve sluiting te garanderen nadat elke nokkenas de klep heeft bediend. De juiste veerstijfheid is essentieel voor een betrouwbare werking van de klepbediening over het gehele motortoerentalbereik.

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.
