The Toyota Camry originally came with a 4-cylinder engine on the other hand soon offered the Election of a V6 engine. When the van loses aptitude, burns oil or runs poorly, a clean compression investigation can diagnose the generate. Parts inside the engine wear gone over clock, and a compression elimination allows you to clock what is ongoing inside of the engine without going to the discontent of tearing it apart.
Instructions
1. Heated up the engine in the Toyota Camry before performing the compression inspection owing to running one on a cool engine produces inaccurate results. Cause positive that the battery is in worthy case, by reason of it Testament occasion to spin the engine diverse times.
2. Disable the ignition course to avoid electrical shock during the catechism. Remove all of the Glimmer plugs and research Everyone one for damage, thanks to it is a indication of damage within the cylinder. Provided the Toyota Camry contains a 4-cylinder engine, there Testament be four Glimmer plugs, but if it has a V6, there will be six.
3. Insert the compression tester into one of the spark plug holes. Crank the starter to rotate the engine and build compression within the cylinder. Compare them to each other. They should be similar and fall within 10 PSI of each other.5.
Write down the compression number for that cylinder.4. Repeat the test on all of the cylinders, keeping a record of the compression numbers.
Compare the compression numbers to the recommended compression ratio. If the Toyota Camry contains a 3.5L or 3.3L V6 engine, the compression ratio is 10.8:1. If it has a 3.0L V6 engine, the ratio is 10.5:1. The compression numbers should fall within 15 PSI of the compression ratio.
6. Add a small amount of motor oil to any cylinders that have a low compression number and perform the compression test again. If the number increases, the cylinder was worn walls or piston rings, but if it remains the same, there are worn valves or valve seats within the cylinder instead.
