One of many vitally important mechanical parts in the engine! If the Valve Rocker Arm
is damaged or the working surface is pitted, the performance will be down, with loss of power, poor gas flow and unpleasant mechanical noise.
During the course of a rebuild, it is a better option to renew the old, worn rocker Arm
, rather than trying to penny pinch and compromise the reliability and long term durability of the valve train assembly.
Helps ensure valves open and shut smoothly. Worn rocker arms mean reduced performance and a noisy top end rattle! Try this pro-workshop gasket seal - 08C70K0234M - for a more professional result!
