How do I know if my cam follower is bad?
Fuel cuts and loss of boost are the main symptoms of a bad cam follower.
What does a fuel pump cam follower do?
The cam follower serves as a barrier between the high-pressure fuel pump and the camshaft that drives the pump. Over time, the cam follower in specific models will start to wear down until there is a hole. As it wears, small pieces and particles can break off and damage the fuel pump as well as the camshaft.

How does a cam follower work?
Cams are used to convert rotary to linear (reciprocating) motion. As the cam rotates, the follower rises and falls in a process known as reciprocating motion. The follower maintains contact with the cam through the force of gravity or by a spring. The total range of movement produced by the cam is called the stroke.
What happens when a cam follower fails?
Like any component, the cam follower will eventually wear. Causes of failure can range from using low-quality motor oil to making improper modifications to the fuel pump. If the cam follower wears all the way, damage to the cam shaft and fuel pump will probably follow.
How long does a cam follower last?
From what we know most vigilant FSI owners check their cam follower every 10-20k miles, depending on the owner.
What is throw cam?
Stroke or throw: The greatest distance or angle through which the follower moves or rotates. It is the maximum distance of followers from the base circle. It is the smallest circle of a cam profile drawn from the center of rotation of the cam.
When contact between cam and follower is rolling is called?
Explanation: It is the angle between the direction of the follower motion and a normal to the pitch curve. This angle is very important in designing a cam profile. Explanation: When the contacting end of the follower is a roller, it is called a roller follower.
