Abstract: An improved cam follower for a vehicle engine includes a body, a spring seat, a tower, a spring and an anti-rotation member. The body defines a body diameter, a first open end, and a second end. The spring seat includes a spring seat opening and an interlock portion. The spring seat may be affixed to the first open end of the body. The spring seat further includes a spring seat diameter wherein the spring seat diameter is greater than the body diameter. The tower may be disposed in a pin housing through the spring seat opening at the first open end of the body. The tower further includes an upper flange and a spring which abuts the upper flange at a first spring end. The second spring end abuts the spring seat. The anti-rotation member accordingly may be coupled to the body via the spring seat.
