As a car enthusiast, I have always been fascinated by the intricate workings of an engine. One of the key components that caught my attention was the valve cover. Not only does it protect the valves, but it also adds to the overall aesthetic of the engine bay. However, during my research, I came across a modification known as LS valve cover spacers and I was left wondering why they are necessary.

First and foremost, LS valve cover spacers provide crucial clearance for aftermarket valve train components. The LS engine is known for its compact design, which means that there is limited space between the rocker arms and the valve covers. When upgrading to high-performance rocker arms or shaft-mounted rockers, these spacers help create enough room for them to operate without any interference.

Moreover, LS valve cover spacers also help in heat dissipation. The LS engine is notorious for its tendency to run hot due to its compact design and tight packaging. This can lead to issues such as vapor lock, which can significantly affect engine performance. By adding a spacer between the valve cover and cylinder head, it allows for better air circulation and heat dissipation, thus preventing overheating.

Another reason why LS valve cover spacers are necessary is that they provide additional clearance for taller intake manifolds or

My Buying Guide on Ls Valve Cover Spacers

As a car enthusiast and someone who has worked on numerous LS engines, I know the importance of having the right valve cover spacers for your engine. LS valve cover spacers are designed to provide clearance for aftermarket valve train components, as well as prevent valve covers from hitting other engine components. In this buying guide, I will share my knowledge and experience to help you choose the best LS valve cover spacers for your engine.

What are LS Valve Cover Spacers?

Before we dive into the buying guide, let’s first understand what LS valve cover spacers are. These are small metal or plastic blocks that are placed between the cylinder head and valve cover to create more clearance between the valve train and other engine components. They come in different thicknesses, ranging from 1/4 inch to 1 inch.

Why do you need LS Valve Cover Spacers?

If you have an LS engine with aftermarket camshafts, rocker arms, or stud girdles, chances are you need LS valve cover spacers. These components can cause interference with the stock valve covers, leading to leaks or damage. By adding spacers, you can ensure proper clearance and prevent any issues with your engine’s performance.

Factors to Consider when Buying LS Valve Cover Spacers

When it comes to buying LS valve cover spacers, there are a few things that you should keep in mind:

Material

LS valve cover spacers come in two materials: aluminum and plastic. Aluminum is more durable and can withstand higher temperatures, making it ideal for high-performance engines. Plastic is lightweight and affordable but may not be suitable for heavy-duty applications.

Thickness

The thickness of the spacer is crucial as it determines how much clearance you will get between the valve train and other engine components. Make sure to measure the distance between your cylinder head and valve covers before purchasing spacers to ensure a proper fit.

Brand

There are various brands that offer LS valve cover spacers, but not all of them may be of good quality. It is essential to do some research and read reviews before choosing a brand. Some reputable brands include Holley, Moroso, and ICT Billet.

Installation Tips

Installing LS valve cover spacers is relatively simple; however, here are a few tips that might come in handy:

– Clean all surfaces thoroughly before placing the spacer.
– Use a gasket sealant or silicone around bolt holes to prevent oil leaks.
– Torque bolts evenly in a criss-cross pattern.
– Double-check all connections before starting your engine.

Final Thoughts

Investing in high-quality LS valve cover spacers will not only improve your engine’s performance but also save you from potential damage or leaks caused by lack of clearance. Make sure to consider factors like material, thickness, and brand when making your purchase decision. And don’t forget proper installation techniques for optimal results. With this buying guide in hand, I am confident that you will find the perfect set of LS valve cover spacers for your engine needs.
