Ford Mustang Exhaust Valve Maintenance Tips 

 September 16, 2022

Most engines will have exhaust valves that are often found towards the back of an engine, but unlike spark plugs and carbs, you don’t really understand just how necessary these valves actually are until they stop working correctly. So without further ado, here are some maintenance tips to ensure your Mustang’s exhaust valves are in optimal shape!


What causes exhaust valves to get loose or stuck open?


One of the most common issues with exhaust valves is when they become loose or stuck open. This can cause a variety of problems, including accelerated wear and tear on the valvetrain, incorrect engine tuning and even decreased performance. To prevent this from happening, follow these maintenance tips to keep your Mustang running smoothly:


  1. Keep the valves clean – Dirty valves cause friction which can cause them to become loose or stuck open. Keeping the valves clean by regularly cleaning the combustion chambers and head with a good valve cleaner will help to prevent this problem.


  1. Check for worn or damaged parts – If you notice any signs of wear or damage on any of the valve components, replace exhaust valve as soon as possible. This will help to ensure that your Mustang runs smoothly and without any problems.


  1. Tighten all the bolts – Always make sure that all of the bolts that attach the valve assembly to the block are properly tightened down. This will help to ensure that the valve is stable and doesn’t become loose or stuck over time.


The Exhaust Valve is the most deteriorated part of the engine


If your Mustang’s exhaust valve starts making a strange sound, it might be time for an overhaul. The exhaust valve is the most deteriorated part of the engine, and as it starts to wear down it will start making more noise and require more attention. Here are a few tips for keeping the exhaust valve in good shape:


– Inspect the exhaust valve for any signs of damage or Wear. If there is visible wear on the valve, replace it as soon as possible.


– Clean and lubricate the valve after every driving session. This will help reduce noise and ensure longevity.


– Check the oil levels in the engine frequently and replace any that are low or running out. This will keep the valves happy and free from debris.


Symptoms that indicate a need for valve maintenance


A Mustang with an exhaust valve issue will typically produce one or more of the following symptoms: rough running, reduced performance, loss of power, decreased fuel economy, and higher emissions. In some cases, a Mustang with an exhaust valve issue may also experience engine light warnings. If you notice any of these problems, it’s important to take action to correct them as soon as possible. Here are some tips for maintaining your Mustang’s exhaust valves:


– When your Mustang first arrives, have the exhaust valves checked by a mechanic. During this check, the mechanic will measure the opening and closing pressures of each exhaust valve and inspect the valve seats for wear or damage. Replacing any defective exhaust valves is essential to ensuring proper engine performance.


– Be sure to change your spark plugs every 10 000 miles (16 000 km) or whenever the engine displays a light warning. Failure to perform this maintenance task can lead to greater emissions problems.


– Keep your Mustang’s intake manifold clean by regularly spraying it with carburetor cleaner or methyl ethyl ketone (MEK). This will help prevent deposits from forming on the air filter and blockages that may cause reduced performance.


Ford Mustang Exhaust Valve Maintenance Tips:


Keep your Ford Mustang’s exhaust valves clean and free of deposits by following these simple maintenance tips.


  1. Clean the exhaust valve stem with a q-tip and hot water every two months or when needed.
  2. Use a valve cleaning solution (available at most auto parts stores) to clean the exhaust valve seats, seals, and stems. Follow the directions on the product package.
  3. Avoid using heavy jacks, objects, or impact tools to remove the exhaust valve covers. Doing so can damage the valves.


Tips on Using a Valve Tool


Valve maintenance is important for keeping your Mustang running at its best. Here are some tips on using a valve tool:


-Clean the valve cover and mating surfaces of the valve with a clean, dry cloth. Use a bit of non-peroxides aerosol cleaner to help if needed.

-Make sure that the tool you’re using is properly fitted and adjusted. It should fit the valve easily without having to force it.

-Loosen the two hex bolts on the top of the valve (one on each side) and remove the cover. On 302/351W engines, you’ll also need to remove the coil cover (3 screws) to get at the valves.

– inspection points: make sure that all debris has been cleared from the bores in which your valves seat; check for any carbon buildup or scoring; visually inspect the valves for damage or leaks; tapping them with a wooden dowel may help determine if they’re sticking open or closed. If necessary, use a valve spring compressor to close any valves that seem stuck open (use caution; this can irreparably damage your engine).
