Compression Check: Specifications

AllData Editors Note - Ford does not provide a cranking pressure specification, only an acceptable range.

Cylinder compression pressure should range between 135 psi (being lowest maximum pressure), and 250 psi (being highest maximum pressure), at an engine cranking speed of 180 RPM minimum. Compression pressure in each cylinder should fall within specified compression range with the lowest cylinder's reading being at least 75% of the highest cylinder's reading.
