How To Remove Broken Valve Cover Bolt


A broken valve cover bolt is one of the most common causes for an engine failure. This can occur due to corrosion or stress fracture which weaken the head gasket, causing it to break down. When this happens, fuel cannot be contained properly and excess combustion takes place, damaging the engine more rapidly.

If you notice your car pulling to one side or another or experiencing vibration while driving, then it’s time to do something about it. Fortunately, there are some easy steps that anyone can take to remove and replace the engine covers themselves.

We will go over these steps in detail here so that you know what to look for and how to do it! If you have ever needed to perform these repairs before, feel free to check out our guide on how to change the oil in your vehicle. It is very similar to changing the engine cover work.

Removing and replacing an engine cover is no small task, but if you are careful and use appropriate tools, then it is totally achievable for everyone.

Look on the underside of the car

If you look close enough, you can sometimes find where the broken valve cover bolt goes! This is not only frustrating because you have to replace this part, but it also signifies that something is wrong with your vehicle.

If you ever notice what seems like there’s no way for the valve cover to fit onto the engine properly then check out the undercarriage of the vehicle. There may be something blocking it or the bolts could be stripped.

This will often indicate a loss in fluid pressure. Make sure all of the fluid filters are up to date and if possible try tightening the bolts yourself as someone else might have already done so.

You may need a new replacement part or tool to do this! Finding one can get expensive quickly, so make sure you do some research before trying.

Look on the top of the car

The first step in replacing your valve cover gasket or installing a new one is to make sure there are no loose parts that could cause damage to the engine. If you notice any screws, washers, or other components floating around inside the engine compartment, they should be glued into place now!

If you take your time when doing this process, I’d recommend using the right tools and working slowly. Make sure not to drop anything down into the engine area as it may get stuck and need help getting out.

Hopefully you will learn how to do this repair yourself here! But if you ever feel overwhelmed or can’t seem to locate something, we are always happy to lend a helping hand for less than $25.

Use a blow dryer to heat the car up

If you do not have access to a tool kit, or do not feel like going to a shop that has one, there is another way to remove this valve cover bolt. Using your own hands, go into high gear!

By now, you’ve probably noticed some weird sounds coming from your vehicle. Unfortunately, most of these noises are bad – they indicate something is wrong with your engine.

If you ever hear strange clicking or buzzing sounds, turn off your vehicle and check out if it helps to make the noise stop. By using your hand, see what kind of effect it will have on the source of the sound.

The best way to use your hand as a solution for an internal part of your vehicle is by heating it up first. A small amount of air flow produced by a hairdryer can help separate stuck parts without needing special tools.

Once you’ve removed all pressure, let time take its course and try again in the morning.

Use compressed air to dry the car off

Once you have determined that your vehicle has a bad check engine light, the next step is to determine what area of the engine needs to be checked. If it is the intake valve cover gasket or the top surface of the head, then start there!

To test the intake valve cover gaskd, you will need to use a good quality hose attachment to connect your compressor to the appropriate place. Make sure to only tighten down each connection as needed, however hard you pressonthehoseattachment!

Once all connections are made and dried, turn on your vehicle and see if the engine runs more smoothly. If so, great! You now know how to fix your engine!

If not, move onto the next part of this guide! You may also want to do an additional test by listening for any sounds related to fluid leaking.

Use a silicone spray to seal the car


Broken valve cover bolts are one of the most common recurring issues that can occur when working with your vehicle. Unfortunately, this will not be the last time you encounter it!

Luckily, there is an easy way to remove them and restore function to your engine. While removing the broken bolt may require some extra effort at first, the long term solution is making sure it does not happen again.

In this article, we will go through all the steps needed to properly fix your car. We will also talk about why using silicon-based products during the process can help prevent reoccurring problems.

Removing A Broken Engine Part

Many times, individuals will try to use brute force to pull out each part of the engine. This approach usually fails as different parts have special internal mechanisms or components attached to them.

Properly dismantling an engine requires using proper tools and techniques. By starting with the least important pieces and working up from there, you can save yourself a lot of headache in the future.

Thankfully, due to advancements in technology, these types of tools exist now. Many people refer to them as robot tool sets or CNC (computer numerical control) machines.

Change the oil

Changing your car’s engine oil is one of the most important maintenance tasks you will do for your vehicle. Engine oils help keep your vehicle running by acting as an electrical conductor, protecting the internal parts of your engine from corrosion and helping lubricate moving components.

Since engine valves work through fluid friction, replacing the engine oil also removes that protective coating. If left untreated, poor engine oil could lead to broken valve cover bolts or even complete loss of engine function.

It is very difficult to tell if your vehicle needs new engine oil unless you perform a full inspection. Since engine oil can vary in brands, it is best to purchase a quart bottle at a local auto store for around $10-15.

Once you have installed the new oil, let the engine run for a few minutes before checking the level. Most engines require 2–3 drops per rotation of the crankshaft. Make sure to check both sides of the pan!

If there are not enough drops after several turns, then add more oil until it feels like it is just barely dripping off the screws. Once it has fully soaked into the cylinders, start testing the pistons for tightness. If they feel loose or hard, then replace the oil immediately!

Removing and changing an engine oil filter is similar to changing a normal size tube of hair gel. While filters may seem expensive, they last for years and can be purchased online or at your local dealership.

Check the coolant level

The next thing you should do is check your car’s coolant. You can either use your car’s manufacturer-provided tool for this or, if you have your own tools, then you can also use that.

You want to make sure that there isn’t too much of it in the engine. If there is more than half full, then you should probably top off the liquid until it is just barely below the line where it drips out. This will ensure that the fluid doesn’t run down the side of the engine due to gravity because it would be covered up by the bottle cap!

If the mechanic hasn’t told you how old the coolant is nor has he/she checked the coolant levels before leaving the shop, get back into the vehicle and check them yourself. Make sure they are all correct as well.

It may seem like a hassle, but having an empty tank can actually damage your engine so don’t take any chances.

Replace the coolant if needed

Another way to remove this bolt is by replacing the liquid in your vehicle’s cooling system. If you are ever unsure whether or not your car needs new coolant, ask yourself how hot it is when you turn on the engine.

If it is warm to the touch, then you know that it is needing fluid! Also make sure that you do not have any cracks in the radiator as this could cause heat damage and leakage.

Removing the air cleaner cover will also allow you to access the valve cover gasket. You can use a tool to press down on this gasket while trying to pull off the old one. Make sure to work slowly and carefully so as to avoid damaging the gaskets or the valve cover itself.

Once you have pulled out the broken piece of metal, replace it with a new one and try again. This process should be done as soon as possible after discovering the problem to prevent more issues from occurring.
