7 Reasons You Have Low Or No Compression In Diesel Engine Cylinders

 As we talked about in an earlier post, there are many things that could lead to an engine failure or the need for an engine rebuild. One such indicator is low or no compression in your engine cylinders.

 

Quite a few things could lead to compression issues in your engine, so proper diagnostics is critical to solving your specific issue.

 

In this post, we're going to cover some of these issues. Be sure to refer to manufacturer specifications or talk to your mechanic to find out if one of these might be the root cause of trouble for your specific engine.

 

INDICATORS OF COMPRESSION ISSUES IN YOUR DIESEL ENGINE

 

Some of the indicators of poor compression are similar to that of fuel contamination—low power and poor fuel economy for example. You might also notice:

Engine running rough

Excessive blow-by

White smoke

 

If you're noticing any of these symptoms in your diesel engine, it would be a good idea to run a compression test to see if low or no compression is the cause of these issues.

 

In many cases, compression problems can lead to the need for an engine rebuild, depending on which components of your engine it affects.

 

CAUSES OF LOW OR NO COMPRESSION

 

While it's good to know if you're experiencing low or poor compression, this is often just a symptom of a larger problem within your engine. There are quite a few things that can lead to compression issues, including:

 

1. LEAKING OR BROKEN VALVES

This allows the compression to escape the cylinder where the issue is located.

 

2. LEAKING OR WORN PISTON RINGS

When these rings wear or fail, compression can leak from the cylinder.

 

3. BROKEN VALVE SPRING

A broken valve spring allows the valve to stay open, which lets the compression leak out as well.

 

4. BLOWN HEAD GASKET

This creates a poor sealing surface, which can allow compression to leak from one or more cylinders, depending on the extent of the damage.

 

5. WORN OR BROKEN CAMSHAFT

Issues with your camshaft prevent the valves from opening the proper amount, which doesn't allow for air and gasses to enter and exit the cylinder.

 

6. BROKEN TIMING BELT OR CHAIN

If this isn't working properly, then the camshaft isn't rotating at a proper speed, preventing compression from taking place as it should.

 

7. HOLE IN PISTON

A hole in the piston would again allow for compression to leak out.

 

MONITORING AND IDENTIFYING COMPRESSION ISSUES

 

Low or no compression can affect one or all of the cylinders in your engine.

 

Running a compression test can help you identify where you're having your issue, as well as helping to narrow down what specifically might be causing your problem. For example, a broken valve can be a reason for no compression in only one cylinder.

 

LOW COMPRESSION IN ONE CYLINDER

Some common causes of low compression in only one of your cylinders include leaking valves, broken valve springs, camshaft wear, broken rings, or a bad head gasket.

 

LOW COMPRESSION IN ALL CYLINDERS

If your test results are showing low compression in all of your cylinders, it might be caused by engine flooding, worn piston rings, cylinder glazing, poor air filtration or dusting, or timing problems.

 

NO COMPRESSION IN ONE CYLINDER

No compression isolated to one cylinder might indicate a dropped valve seat, broken valve spring, dropped valve, broken valve, or piston damage.

 

NO COMPRESSION IN ALL CYLINDERS

If you're experiencing no compression in all of your cylinders, it might be caused by a broken camshaft.

 

WHAT TO DO ABOUT COMPRESSION ISSUES IN YOUR DIESEL ENGINE

Again, a compression test can help you narrow down where your issue might be. Running a compression test helps you to know how your engine is performing year-to-year (or however long you go between compression checks), as well as how your cylinders are doing compared to each other.

 

This allows you to isolate the problem, whether it is in one, two, or all cylinders.

 

A compression test can be run through the glow plug holes or the injector holes, depending on the engine specifications and the type of gauge you're using. Refer to manufacturer instructions for more information on your exact engine type.
