Understanding the Importance of Oil Pump Gaskets
When I first started working on my Small Block Chevy, I quickly learned that the oil pump gasket is a crucial component. It plays a vital role in sealing the oil pump to the engine block, ensuring that oil doesn’t leak out. A reliable gasket helps maintain the engine’s oil pressure, which is essential for lubrication and overall performance.
Material Choices
I’ve found that oil pump gaskets come in various materials, each offering different benefits. Some are made from rubber, while others use cork or composite materials.
