What is loose compression?

Loss of compression is caused by bad internal engine wear or internal engine failure. Both mean the engine will need serious repair


How do you tell if piston rings are bad?

The engine will be losing compression, and possibly burning oil. Check each cylinder to determine the compression. The loss could also be caused by a valve problem.


How do you get compression back in an rx 7?

If you have loss of compression then a full rebuild of the engine is most likely needed.


Why does the Ford Ranger have a loss of power?

Loss of power could be caused by many things. The engine could have a fuel pressure issue, or there could be low engine compression among many things. A check of computer codes may give an idea of where to start troubleshooting.


What happens if your valve oil seals wear on a car engine?

Oil leakage and loss of compression and power loss.


Loss of compression on 3 cylinders?

Most likely it's caused by a damaged head gasket when the head warped. Has the engine overheated at any time in the last few thousand miles?


What happens to an engine with compression loss?

Why no spark plugs for diesel engine?

Because a diesel ignites due to the heat caused by the compression pressures in the diesel engine.


What are signs of broken ring in v8 engine?

Oil burning or loss of compression on any one cylinder. It may also be missing on one cylinder. A compression test will verify this.


Why is my Engine power loss and why is there oil on spark plug boot?

Engine power loss and oil in a spark plug boot is caused by one of two things, either a cracked valve covor gasket that is letting oil seep into the boot at the top........or even worse a blown head gasket, i would sugguest a compression test to determine the problem


Can low compression on an engine damage a engine?

Low compression indicates that engine damage already exists. An engine's compression will be lost if: there is damage or wear to the pistons or rings there is damage or wear to the valve train there is damage or loss of seal on the cylinder head There are some other factors as well, but these three cover most.

Which engine has highest compression ratio?

the diesel engine. it takes one ignition to start, then it runs off of (autoignition) ignition from heat caused by high compression. compression ignition (autoignition) causes ignition to happen a little earlier than spark ignition engines (gas engines) which is less vulnerable to risk of engine knocking or wasted power when dealing with high compression. -maddmatt
