1
Gather the necessary equipment. Before getting started, you'll need to assemble the tools and equipment necessary to properly clean your cylinder heads. Much of what yous'll need tin exist found around the house, though you lot will as well need to employ a chemical parts or brake cleaner that can exist purchased from your local auto parts store. You volition also need access to warm water to soak the heads. Gather the following supplies before getting started:^[ane]
- Brake or parts cleaner
- Canned air or access to an air compressor
- Ii large tubs or buckets
- Paper towels or rags
- Plastic scraper
2
Ensure the caput is completely disassembled. When fully assembled, cylinder heads contain numerous minor parts that need to be removed earlier the cleaning process can begin. Most cylinder heads contain ane or ii camshafts, intake and exhaust valves with supporting hardware, and likely some ignition components such as spark plugs or ignition coils. All of these parts must be removed and stored safely while cleaning the cylinder head.^[2]
- Use intendance when removing the valve cover on the meridian of the cylinder caput to forestall information technology from warping. Loosen all of the bolts showtime, and then proceed to unscrew them the rest of the way.

- A magnet volition non stick to an aluminum cylinder caput, but it will stick to an iron one.

Use a plastic scraper to remove head gasket material. In that location is a good run a risk that in that location will even so be some caput gasket material remaining on your cylinder caput. The head gasket creates a seal between the head and engine block (likewise sometimes referred to as the "summit" end and "bottom" ends). Scrape off any remnants of the gasket using a plastic scraper. Be extremely careful not to scratch or damage the "mating surface" of the cylinder head where the gasket material tin can be found. Whatsoever scratch or damage tin can cause leaks that volition lead to gasket failure once the engine is assembled once again.^[4]
- Practise non utilize a metal scraper or any tools that could feasibly damage the mating surface of the cylinder caput.
- Make certain to get all of the previous gasket material off of the head to let for a proper seal when reinstalling.

vi
Remove the head and use a rag to wipe it downwards. Later waiting a few minutes, advisedly lift the head dorsum out of the tub of water and place it on a stable counter. Use a make clean rag to wipe the cylinder head down and remove every bit much water from it as possible. Brand sure to wipe out any continuing water that may collect in the nooks and crannies of the head.^[ix]
- You will not be able to completely dry out the cylinder head with a rag, but removing the majority of the water will help information technology to dry faster.

7
Utilise a spray washer to clean the head. If you have admission to a spray washer, which is a specific type of equipment designed to clean automotive parts, you tin do a more than constructive job of cleaning the external and exposed internal areas of the cylinder head. Like cleaning it by hand, spray washers do a poor job of cleaning the internal surfaces that are hard to reach, simply tin dramatically reduce the labor required to clean the remainder of the cylinder head.
- Spray washers are common in many professional garages and automobile shops.
- Smaller spray washers can be purchased at auto-parts stores, though the cost may be prohibitive if you practise not intend to clean other parts.
viii

This will dry the head as well as removing any dust or other debris that may have fallen into the head during the cleaning process.^[10]
- Spray air into every opening y'all can find in the cylinder caput to ensure there is no remaining moisture or debris anywhere in the head.
- Make certain that in that location is no debris of any kind in the cylinder head. Even small amounts of debris tin seriously harm the cylinder head in one case installed.
2
Allow the caput to dry completely. Leave the cylinder head on a counter to dry completely. Place paper towels over the top of the head to ensure dust does not fall into and settle in the newly clean and debris free head.^[11]
- Do not store a caput while moisture. Atomic number 26 heads, in detail, will oxidize and rust if stored wet.

When I was changing spark plugs on my auto, some dirt barbarous into the combustion bedroom. How practice I clean it out?

You could remove the cylinder head to do this, but if it was but a little chip of dirt, so information technology will probably exist fine. In the futurity, utilize compressed air and make clean all the dirt away from the spark plugs earlier yous remove them.
