Loss of compression can be due to old engine or problem in cylinder head gasket causing leaks.
If you don't know what to do consult or look for professional mechanic.
Recommendation: Replace engine if you over-used it. Like reaching high mileage over 100,000 or 200,000 or 300,000 miles.
-------------------------------------
The engines that i typically see with low or uneven compression have burned or warped valves. Occasionally the rings are bad but that is unusual. The definitive test is to run a cylinder leak down test. You hook an air compressor up to a cylinder with a special tool . If air leaks out of the tailpipe then it is a bad exhaust valve. If air comes out of the Air filter snoot then it is a bad intake valve. And if air comes out of the Valve cover oil fill cap then it is the rings
Severe compression injuries affect the brain causing hematomas. Symptoms include loss of smell, double vision, brief loss of consciousness, confusion and loss of motor skills.
To clean the air that is to be mixed with fuel in the carburetor.dirty air can cause cylinder to score, the rings will wear causing loss of compression,and oil. this will lead to loss in performance.
Data Compression is a technique to minimize the space used by data in storing. So when we do compression of data, no data is loss.
loss of compression, loss of power, oil is "milky"
Tension and compression takes place when an object has a force on another object. The tension is when the force is causing a pulling effect on part of the object. The compression is when the force is causing a contracting effect on part of the object.
Thare are a number of things that could cause compression loss, Like bad valve, rings, or the head gasket.
Loss of Power
If you have loss of compression then a full rebuild of the engine is most likely needed.
heavy Knocking, and loss of compression.
loss of power
CFC's are causing loss of ozone layer. They react with ozone to deplete it.
Did you check for compression loss? or Is the catalytic convertor blocked?
