Valve covers are an important part of your engine. Not only do they help to keep the engine looking good, but they also protect the valves. If you’re not happy with the way your valve covers look, or if they’re starting to show signs of wear and tear, it’s time to paint them. In this article, we will discuss how to paint valve covers in a step-by-step manner. We’ll answer some common questions and provide some useful tips that will make the process easier for you. Let’s get started!
How to Paint Valve Covers?
You’ll need:
- Valve covers
- Sandpaper (600 grit)
- Primer
- Paint
- Clear coat
Instructions
Before you start painting, it’s important to sand the valve covers.
This will help prevent runs and drips in your paint job. Finally, once the paint is dry, you can apply a clear coat for added protection. [1]
What paint can you use on a valve cover?
Spray paint is the most common type of paint used on valve covers. However, there are a few other types of paint that can be used. These include:
- Aerosol spray paint
- Brush-on enamel
- Roll-on enamel
Aerosol spray paint is the easiest type of paint to use and will give you the best results. Brush-on enamel is also easy to use but can be difficult to get an even coat. Roll-on enamel is the most difficult to use but will give you the best results. [2]
Can you paint a valve cover?
Yes, you can paint a valve cover. You’ll need to sand it down first to get the paint to stick, and then you can use any kind of paint you like. Just make sure that you let the paint dry completely before putting the cover back on the engine.
Can you use normal spray paint on the engine?
No, you should not use regular spray paint on your engine.
Some people recommend using a powder coating instead of paint. Powder coating is more durable and will not peel or chip under high temperatures. However, it is also more expensive. If you decide to powder coat your valve covers, be sure to follow the instructions carefully.
Do you have to use high temp paint on valve covers?
No, you don’t have to use high temp paint on valve covers. You can use any type of paint that you want. However, if you are going to use high temp paint, make sure that you follow the directions on the can carefully.
Can you paint a valve cover without removing it?
It’s possible to paint a valve cover without removing it, but it’s not recommended. It’s much easier to remove the valve cover and lay it flat on a surface so you can evenly apply the paint. Plus, if there are any nooks or crannies that need painting, it’s much easier to do when the valve cover is removed.
If you decide to paint the valve cover while it’s still on the engine, be sure to tape off any areas that shouldn’t be painted, like electrical connections. And use a small brush or Q-tip for hard-to-reach spots.
Once you’re finished painting, let the valve cover dry completely before putting it back on the engine. Otherwise, you run the risk of getting paint everywhere!
Can you paint plastic valve covers?
The answer is yes, you can paint plastic valve covers. However, there are a few things to keep in mind when painting plastic valve covers. First of all, make sure that the plastic valve cover is clean and free of any dirt or debris. You can use a mild soap and water solution to clean the valve cover. Once the valve cover is clean, you will need to sand it down with fine-grit sandpaper. This will help to create a smooth surface for the paint to adhere to. After sanding, wipe down the valve cover with a damp cloth to remove any dust particles. [3]
Now that your valve cover is prepped and ready, you can start painting! When choosing a paint for your project, it is important to select a paint that is specifically designed for plastic surfaces. These paints will have a lower level of adhesion and are less likely to crack or peel over time. Once you have your paint, apply a thin layer evenly across the surface of the valve cover. Allow the first coat of paint to dry completely before applying a second coat. After the final coat of paint has dried, you can reattach your valve cover and enjoy your new paint job!
Does a valve cover need heat-resistant paint?
If you’re looking to get the best results possible, then yes – heat-resistant paint is essential. Not only will it stand up to the high temperatures that your engine produces, but it will also provide a much more durable and long-lasting finish.
There are several brands of heat-resistant paint on the market, so doing some research and finding one that suits your needs should be easy enough. Once you’ve got your hands on some quality heat-resistant paint, simply follow the instructions on the tin and you’ll be good to go!
With these simple tips, you should have no trouble getting a great finish that will last for years to come.

Once the primer is dry, you can begin applying your chosen paint color. For best results, use several thin coats. Allow the paint to dry completely between each coat. [5]
