If you’re building, upgrading, or restoring an LS-powered vehicle, choosing the right valley cover is essential for maintaining engine reliability and achieving a clean, professional finish.
At CNC Manufacturing, we supply high-quality LS2, LS3 and L98 Valley Covers designed to suit a wide range of Holden and GM LS engine applications.

What Does a Valley Cover Do?
The valley cover sits between the cylinder heads and seals the engine’s lifter valley. Its primary role is to:
- Protect internal engine components from contaminants
- Maintain proper oil control and sealing
- Support crankcase ventilation systems where applicable
- Provide a clean and professional engine bay appearance
A quality valley cover is particularly important for modified and performance LS engines where reliability and durability are critical.
