You got a 2005 Chevy cavalier with no compression what causes this and how much too fix it?

Answer 1

Typically the engine's internal components operate within tight tolerances of each other. Compression loss either through ware or mechanical failure can result in a car which runs poorly or not at all. Compression loss can occur over time, through warring of the piston wrings or suddenly, through mechanical failure. Sudden failures can include head gasket blowout, bent or broken valve and cracked cylinder walls. All of these causes have special characteristics which a trained technician can identify through simple observation, specialized tests such as compression and leak-down testing, and sometimes only through exploratory surgery by removing the cylinder head and visually inspecting the engine's internal components.
