In this test, a product is attached to a leak tester and filled with air. Once pressurized, the air source is valved off and the pressure is allowed to settle. If it turns yellow, you have a leak. If it stays blue you are ok. The directions just say if it turns yellow, nothing about staying yellow. Mine turns yellow quickly, then slowly turns back to blue. I was expecting it to be like a pregnancy test and stay positive if it is positive. BTW, engine has 209K on it 3.4L V-6.
vacuum method (sometimes known as an “outside-in leak”), where the direction of flow is into the test specimen (pressure inside the specimen being less than ambient pressure), and the b. positive pressure method (often referred to as the “inside-out leak”), where the fluid passes from inside the test specimen outward (pressure inside .
