A leakdown test is one way a mechanic can find whether an engine has an internal problem instead of something external, like a bad spark plug The leakdown test measures pressure loss inside a cylinder This procedure is different — and usually more accurate — than a compression test, which just measures the pressure inside a cylinder. Cylinder Leakage Test Performed a cylinder leakage or leakdown test after a cylinder balance, and a cylinder pressure test has verified a problem with the cylinder It shows the percentage of leakage and pinpoints the part causing the compression leak Remove the spark plug and place the problem cylinder at (TDC) top dead center of the. Leak test procedure Don’t forget the following important points when leak testing • Review the F Gas log (see section 9) to check where leaks have been found previously • Choose the most appropriate method, for example a quick sweep with an electronic leak detector followed by a leak detection fluid (soapy water) to pinpoint the leaks.

There are several advantages of industrial leak testing using helium as test gas The detectable leak rates are significantly lower than the leak rates which must be detected in practice;. Leak testing methods Linear scaling of the final leak rate value This method uses a single scaling factor to scale the measured leak rate so that at the end of the abbreviated test, the value is the same as a fulllength test When the test is run, only the final scaled value is compared to the leak limits. The Mass Spectrometer measures the helium leakage and sets the pass/fail decision The test piece pressure is often compared to the chamber pressure before dosing with helium, to avoid saturating the Mass Spectrometer in the event of a gross leak For more information see our guide on Helium Leak Testing.
