The compression pressure specs above are for a warm engine, so don't be alarmed if this test comes out a bit low. This test serves 2 purposes. First, if you keep a record of the readings, a comparison of cold/warm deviations over a period of time will give you nearly as good a picture of engine …

The compression test uses a gauge to measure the build up of pressure inside each cylinder as you crank the engine. The cylinder leakage test uses compressed air that is forced into the combustion chamber. Both testers are screwed into the sparkplug hole. To check the condition of the rings, you need a leak down test. This test measures the ...

51. A dry compression test followed by a compression test can verify the piston ring condition. 52. Cylinder tests can pinpoint . the cause of a low compression problem. 53. A cylinder test can check if all the engine’s cylinders are producing the . same amount of power. This is sometimes known as a cylinder contribution test. 54.

This explains mild smoking upon cold start-up and the change in compression characteristic in test car #1. *Like millions of ball bearing. 5. Conclusion. Our tests results show that the Friction Free 3000™ oil additive increases gas mileage while it reduces oil consumption. The additive also increases engine compression and reduces auto emission.
