Why is there no compression in cylinder 2?
Engines aren’t that much different from one brand to the next. The issue for independent mechanics is access to parts and information. cylinder 2 has no compression due to the valve spring not shutting. If the valve spring is broke it can be replaced without removing the cylinder head.
What causes engine compression to be too high?
Another possibility is a broken camshaft in the area that operates valves for two adjacent cylinders. Furthermore, The engine compression could be too high in one or more cylinders. This would be an indication of excessive carbon buildup in the engine.
What to do if you have low compression in your engine?
Consequently, a cylinder leakdown test, needs to be performed, if low compression is found. This will assist in diagnosing, what is going on inside of the engine. This test pinpoints specific leakage. This test uses a set of pressure gauges with a regulating device and can, quantify the percentage of leakage.
What does it mean when compression reading does not change?
If the compression readings do not change, then it would indicate a timing problem. If a valve seat cracks it will allow hot gases to leak; burning both the valve seat and the valve. Most cylinders heads are made of aluminum and expand at a different rate; compared to the metal valve seat.
What to do if compression in one cylinder is low?
The first step to repair is to be sure that the compression in one of the engine cylinders is actually low. Use a compression gauge to check the measurement. In case you don’t have one, take the car to an auto servicing shop so that a mechanic can do the testing.

What does trouble code p0302 mean on cylinder 2?
If the P0302 trouble code returns, an inspection of the cylinder 2 compression system will be done (this is not common). If the P0302 trouble code is still unresolved, a problem with the powertrain control module is possible (this is not common).
Why is there a trouble code on my cylinder 2?
This type of code is usually an indication that the car needs a tune up, so replacing one spark plug will normally not resolve the problem. In order to make a quick determination about whether a faulty wire or coil pack is causing the misfiring problem, switch the wires or coil pack for cylinder 2 with another cylinder’s wires or coil packs.
What causes a car engine to lose compression?
There are several causes you can eliminate if your cylinders are losing compression. One possibility is a blown head gasket. The head gasket connects to the cylinder head at the top of the engine. If there is a problem, you’ll notice a gap between the cylinder and the head, and gas will escape the cylinder, leading to low compression.
Can a car have more than one cylinder?
But since most cars have anywhere from four to eight cylinders in them, it’s also not uncommon for people to experience compression problems with more than one cylinder. You might find that several cylinders have low compression, or you might even discover that all of your cylinders have low compression.
Can a blown head gasket cause low compression?
If two cylinders next to each other both have low pressure, a blown head gasket is a likely culprit. If you discover you do have low compression, the only solution is to replace the leaking part whether it’s the piston, piston ring, camshaft, head gasket or valves.
Can you drive with low compression in one cylinder?
In order for you to drive around in your car without experiencing any issues, you obviously need it to be firing on all cylinders so to speak. But if there is an issue with the compression in your car’s engine, there is a chance that you might find yourself driving with low compression in one cylinder.
Why do I have no compression in my engine?
If you are getting no compression at all in your cylinders, you probably have a bad timing belt or a broken camshaft. Now that you know some of the most common causes of low engine compression, what should you do about it?
Why does cylinder 2 on my Kia have no compression?
I mechanic friend from church did a diagnostic test and told me cylinder 2 has no compression due to the valve spring not shutting. He recommended i take the car to a Kia dealership to have it fixed since he is not comfortable with the engine and brand.
But since most cars have anywhere from four to eight cylinders in them, it’s also not uncommon for people to experience compression problems with more than one cylinder. You might find that several cylinders have low compression, or you might even discover that all of your cylinders have low compression.
What can cause a car to have no compression?
Running rough or losing power, there may be a lack of engine compression in one or more cylinders. Internal engine damage can be detected by checking engine compression. Leaking valves. Leaking piston rings. Excessive carbon buildup. Broken Valve Spring. Blown head gaske t. Worn camshaft. Bent pushrods. Broken timing belt or chain. Hole in piston.
How much compression should I have in my engine?
There are some other causes of low engine compression but, these are by far the most common. You should be aware of these problems; so you can make an informed decision when investing in repairs. As a rule, most engines should have, 140 to 160 lbs. of cranking engine compression.
Where does compression come from in an engine?
If there is a leak on the valves or the valve seats, the compression will leak out into your exhaust or the intake during the combustion process. In older engines, you had to resurface these valve seats several times during the car’s lifetime.

How do you do a compression test on a car?
To do this, you should purchase a compression gauge to do a compression test. Make sure you disable the engine, so it does not start while you are testing the cylinders. Remove the ignition coil and spark plug from the cylinder you’re testing. Insert the compression gauge extension and screw it in.
