Instructional video showing how to check compression using a differential compression tester on on Lycoming engine. The compression test is a very useful tool to help determine the internal condition of cylinders, but it has limitations and must be used in conjunction with other non-invasive tests. . Service Instruction No. 1191A spells out the criteria for performing compression checks on Lycoming engines. Below is an excerpt from 1191A.
cylinder differential pressure test a regulated test pressure of eighty pounds per square inch (80 PSI) is directed into the cylinder with the piston at top dead center at the end of the compression stroke and the beginning of the power stroke. Eighty pounds per square inch (80 PSI) is used as a test pressure for safety reasons and is A quick rundown on a Continental O-200 engine compression test procedure on a 1946 Luscombe 8A/O-200. Typical for most light aircraft engines.
(For most compression test gauges, this value turns out to be in the low 50s or high 40s.) Alternatively, your mechanic can purchase a compression tester (like the Eastern Technology Corp. Model E2M) that has the calibrated master orifice built right in. Turn a valve one way and the gauge measures the leakage through the master orifice to .
NOTE: The ATS 2EM Differential Pressure Tester has a .040” orifice as required by Teledyne Continental SB03-3 Service Bulletin, and is the proper type of instrument to test ALL Teledyne Continental engines in accordance with the aforementioned bulletin. The ATS 2EM also complies Textron Lycoming SI-1191A Service Instruction and is appropriate for ALL Textron Lycoming .
However, Lycoming and Continental service specifications call for the use of a standard tester (with a .040" orifice) even if their engine’s bore diameters exceed 5", and for those engines you must comply with the manufacturer's specifications and use a standard tester such as the 2EM instead of this unit. . Does this compression tester .
The ATS 2EM also complies Textron Lycoming SI-1191A Service Instruction and is appropriate for ALL Textron Lycoming engines as indicated in the Service Instruction. For all other makes of engines, consult FAA AC43.13 REV 1B for guidance in selecting the proper instrument for your engine. . then the Compression Tester Extension may be just .

It has an 0-320 with compression testing warm at #1 78, #2 70, #3 78, #4 70. 250 hours ago #1&3 cylinders were rebuilt. . Lycoming's guidance and it is just that..guidance says: Interpretation of the results of the test is highly depndent on the skill and judicious opinion of the tester; however, the following observations cover the principle . In fact I did one today on a Maule MX-7 /180..or should I say I coached the owner thru the evolution. The compression on the cylinder was 40/80 cold, after the compression was 76/80 cold. The owner called me because the A&P wanted to pull the cylinder, and send it out to be re-built. Fixing a cylinder in place is always better.
I tested my own Lycoming O-360 with an admittedly old automotive compression tester and got these results: #1-150 psi, #2-155 psi, #3-150 psi, and #4-120 and 130 psi in two tests. As a double check, I did a differential compression test on #4 and got a reading of 76/80.
Model E2A Tester, for cylinders of less than a 5.00 inch bore* with a .040 inch diameter orifice, that eliminates all guess-work by enabling you to determine the exact location and cause of your engine's efficiency loss.
