Why do we need to know the engine compression requirements?
By performing a compression test, internal engine malfunctions; such as bad valves, piston rings or excessive carbon buildup can be detected, before they cause irreparable damage. It benefits the owner to be aware of these problems; so they can make an informed decision about the results.

What happens if you break a compression cylinder?

Why did my Dodge truck fail the compression test?
