#HOMEMADE COMPRESSION TESTER HOW TO#
How to perform a compression test to identify damaged pistons worn rings burnt valves and blown head gasketsA compression test kit on Amazonhttpswww. Put the compression test adapter into the engines first cylinder. This test indicates whether the valves head gasket or the piston rings are at fault. Once you have the results you compare your gauge reading to manufacturer specifications and interpret your results. Procedure for compression test of concrete Clean the cylinder mould and coat the inside lightly with form oil then place on a clean level and firm surface ie the steel plate. STEP 1 Remove the fuel pump and fuel-injection fuses. Now turn the key and crank the engine over for about 10 seconds. Note the circular cylinders and the timing belt on the engines front. Inject a small amount of oil usually about a tablespoon into the cylinder and rotate the crankshaft about six turns of so.Ī compression test can also inform of an individual cylinder problem which can be repaired. If you dont have a remote starter switch have a friend turn on the ignition until the engine cranks over about six times. Be sure to keep the gauge plug firmly inserted while the engine is cranking.Įspecially if your vehicle requires welding. Compression Testing and What You Can Learn From It - EricTheCarGuyHere is a video on performing a compression test on an engine to assess its mechanical con. To perform the engine compression test get the appropriate compression gauge for your vehicle. This will help prevent erroneous compression readings. This test method consists of applying a compressive axial load to cylinders at a rate which is within the prescribed range until failure occurs. How to Do the Compression Test Youre ready to begin the test if the compression gauge is in place. Otherwise press the button of the remote starter switch. You can compression test the cylinders with the help of a compression gauge. Look down on the engine to figure out which cylinder is closest to the front of the engine.
Tighten the connector to form a seal in the cylinder.
#HOMEMADE COMPRESSION TESTER INSTALL#
Install it on the first cylinder where the spark plug should be. When testing a diesel engine use a gauge designed for diesel since it has a high compression tolerance.
Disconnect the main wire to the coil and spark plug. The pressure will attain the highest reading after 4 or 5 compression strokes. Youre all set up now and ready to actually do the compression test.Īfter pulling in the air and fuel during the intake stroke the piston is now forced back up in the cylinder compressing that air and fuel mixture. The first cylinder is on the rightmost ones in most engines.
How To Do A Compression Test Dry Start with a warm engine the ignition and fuel disabled and all spark plugs removed. The compressive strength of the specimen is calculated by dividing the maximum load attained during the test with the cross-sectional area of the specimen. In addition always wear protective clothing and gloves while working around a hot engine. Ask someone to start the engine or use a remote switch and watch the pressure build up on the gauge.Ĭylinder compression can inform you on how much wear an engine has on. This is the stroke in which you will be performing the compression test. Scotty Kilmer mechanic for the last 46 years and counting shows how to check the compression pressure inside your engine. The needle on the compression gauge will stay at the highest indicated compression reading. This mixture must be placed under pressure in order for the engine to create any power. Once youve found it put your test compressors hose in the spark plug slot and turn it clockwise by hand until its locked in place. Perform a wet compression test if a cylinders pressure is below specifications. All you have to do is connect the gauge in place of a spark plug and test each cylinder pressure in turn. With a compression tester a few hand tools and 20 minutes you can try this yourself.Ĭompression Tester By Cascao Had Made Years Ago An Engine Compression Tester Material 0 300psi Manometer High Pressure Hose Compression Tester Engineering Double check that you disconnected the appropriate stuff so the engine doesnt actually start. You might also want to invest in some quality steel toe welding boots to protect your feet.
