When tightened down, the cylinder head crushes the head gasket into the cylinder block, causing any imperfections to be sealed by force. What are the symptoms related to a bad head gasket?
Do you need a head gasket replacement on a Nissan?
With the reliability that late-model cars and especially their engines enjoy, we don’t find ourselves doing too much heavy engine work anymore. Many of us miss the feeling of accomplishment we’d get when completing an in-house engine rebuild.
When to take compression for head gasket replacement?
While taking compression is an important step, only the most severe cases of head gasket leakage will be found using this method. But it will give you a quick indication of the engine condition and help you determine the best strategy for this repair.
When to replace the head gasket on a Nissan Altima?
Nissan marketed some Altimas and Sentras with 2.4-liter engines from 1999 to 2006. If you happen to have one of these vehicles, there may come a time you need to replace the head gasket due to an overheated engine or worn parts.

What happens if you have a bad head gasket?
Driving with a bad head gasket is hazardous to the engine, and may even be impossible.

How do you test engine compression in a Nissan Altima?
Which means you simply remove the spark plugs and check each cylinder’s compression. The second test done is a ’wet’ compression test. In this second test, you add a few drops of engine motor oil to the cylinders that registered low or 0 compression.
Where is the first cylinder on a Nissan Altima?
An important thing to understand when finding the location of cylinder one is that it’s going to be the first cylinder in the firing order of the vehicle, and not the first cylinder that you might see when looking at the engine. The P0301 Nissan trouble code will trigger the Altima’s service engine soon light.
What causes a compression leak in the head gasket?
More likely however is the scenario where the pistons themselves are intact, but the piston rings were damaged from overheating and are failing to seal the gas inside the cylinder. If you have low compression in all cylinders, this is often the culprit. Also, your compression leak may not be in the pistons or head gasket but in the valves.
Why does my Nissan Altima have a blown head gasket?
Normally, when the head gasket fries in your Nissan Altima’s (or Frontier, Xterra), the coolant will mix with the engine oil, but not always. This is why one or maybe two more tests are needed to make sure that the head gasket is really blown or not.
Which means you simply remove the spark plugs and check each cylinder’s compression. The second test done is a ’wet’ compression test. In this second test, you add a few drops of engine motor oil to the cylinders that registered low or 0 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.
