Valve Spring Cap - Cylinder Head DD16 EPA07/EPA10
Detroit Diesel

The valve spring cap for cylinder heads serves as a critical interface between the valve spring and the valve retainer, ensuring that the spring remains securely seated during engine operation. Its steel construction provides the necessary strength to withstand the high compressive forces exerted during valve closure. With a height of 11 mm and an outer diameter of approximately 28.80 mm, this component ensures proper spring positioning, which is vital for maintaining correct valve timing and preventing spring dislodgement. Proper installation of this cap reduces the risk of valve train failures, which can lead to costly engine repairs.
