How to Check Valves Without Removing the Head
How to Check Valves Without Removing the Head.
Are you concerned about bent valves in your engine but want to avoid spending unnecessary money?
If you believe that your vehicle has a bent valve, or if your vehicle has recently been diagnosed, the notion of additional mechanical failure and additional expenses might be immensely overwhelming.
However, in this post, we’ll show you how to tell whether your vehicle has a bent valve and how to inspect for problems without needing to visit a mechanic. Read on to learn more about the symptoms and how to successfully remove your engine’s head at home.
What Are the Common Signs and Symptoms of Bent Valves in Your Engine?
When a valve bends, it becomes nearly impossible to avoid costly subsequent repairs. Continue reading to find out why your vehicle is having these issues:
1. Turning on the Engine Light.
Bent valves unavoidably result in additional mechanical problems, which are normally recognized by sensors. However, valves are not considered electrical components. The dashboard of your vehicle can exhibit a common example of misfiring.
2. Unsatisfactory Performance.
Your vehicle’s valves must open and close at the precise functional times in order to conduct the predicted combustion execution. When your vehicle’s valve is bent, however, performing this task becomes nearly impossible. This means that the surrounding components will start working to compensate for the bent valve.
3. Rowdy Engine
Unfortunately, you’ve probably realized by now that belt valves almost always cause further mechanical harm. Misfiring is prevalent when a valve is deformed; this is usually the result of a faulty timing belt. A broken timing belt, for example, can have an effect on the engine’s overall performance. If you’re nodding along as you read, you must have heard unpleasant noises from your car’s engine as well.
When you’ve determined that you’re dealing with bent valves, the next step is to inspect them and plan for any necessary repairs or replacements.
The valves in your car are in charge of generating the necessary pressure to accomplish the proper combustion procedure. Testing your vehicle’s valve compression can be done without having to remove the head, saving you time and money.
What Are The Tools Required To Perform A Compression Test?
- Compression Tester And Kit
- Spark Plugs Socket
Step 1: To begin testing, the engine must be turned off. If you have an older vehicle, find the distributor coil and begin by deactivating the coil while there is still current available. If you need to remove the spark plug wires from your vehicle, make a note of them first. This is to guarantee that the replacement is done properly.
In newer models, however, you must identify the coil-on-plug and then carefully remove each plug. You’ll be looking for the appropriate fuse for your vehicle’s ignition system.
Step 2: Use a spark plug socket to begin removing the spark plugs from your engine. This is simply to check that the engine of your vehicle does not spin during compression testing.
Step 3: Check your compression test gauge to ensure you’re testing appropriately in either diesel or gasoline. Driving a diesel vehicle, on the other hand, can be a little more difficult. You’d need to start by removing the glow plugs. This can be accomplished by utilizing a particular adapter, referring to the available spark plug set up – this will now serve as the connection for testing. Use your notepad again in this stage to carefully remember each cylinder reading.
Step 4: To finally do the compression test, start your vehicle’s engine. Asking a friend to help with the test is not only convenient, but it also avoids mistakes that are made when working alone. Accelerate a few times to get a good reading—this definitely helps the testing be more accurate.
Testing Result: After testing the compression reading process several times, you should have a notebook full of different results. If any of the readings result in a single low number or a series of low values, this indicates that the highest pressure cylinder is exponentially higher than the lowest pressure cylinder. Each reading that indicates lower compression indicates insufficient valve performance.
