Compression Check: Specifications
The indicated compression pressures are considered within specification if the lowest reading cylinder is within 75 percent of the highest reading. Refer
to the Compression Pressure Limit Chart.
If one or more cylinders reads low, squirt approximately one tablespoon of clean engine oil meeting Ford specification ESE-M2C153-E on top of the
pistons in the low-reading cylinders. Repeat the compression pressure check on these cylinders.
