Compression Check: Specifications

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

Cylinder compression pressure should range between 134 psi (being the lowest maximum pressure) and 250 psi (being the highest maximum pressure) at an engine cranking speed of 180 RPM minimum. The compression in the lowest cylinder should be at least 75% of the highest cylinder's reading.
