The engine in the Honda Agree changed many times over the second childhood. If any of the cylinders produce a low reading, add a capful of motor oil and perform the compression test again.6. Re-evaluate the new results. If the compression number became higher, the piston rings or cylinder walls need repair.
1. Launch the catechism by elementary warming up the engine in the Honda Assent. A compression test performed on a bleak engine Testament be inaccurate. Brew definite the battery is again in pleasant instance over it Testament demand to spin the engine various times during the catechism.
2. Break off the engine and remove the Glimmer plugs so that the starter spins the engine freely. Provided the Honda Accord has a 4-cylinder engine, there Testament be only four, but if it has a V6 engine, be sure to remove all six. Disable the ignition system also to avoid the possibility of electrical shock.
3. Place the compression tester into one of the spark plug holes and crank the engine. This builds compression on account of cylinder. Record the results for comparison later. Do the same to all of the four or six cylinders, depending on engine size.
4. Evaluate your test results by comparing them to manufacturer specifications. If the Honda Accord is a 2008 model with a 4-cylinder engine, the recommended compression ratio is 10.5:1, but if it is a 2003 through 2007 model, the number should be 9.7:1. A 2003 or newer model containing a V6 engine should have a compression number of 10.0:1.
5. Determine if there is a problem inside the engine. If the test result number is off by 15 or more PSI, something is wrong. The numbers should also be within 10 PSI of each other. If it has an older 4-cylinder engine or a newer V6, it's meaningful to conserve it running properly. Over allotment, parts wear away causing the engine to lose faculty, burn oil or break poorly. A compression check is a facile, inexpensive behaviour of finding away what is amiss inside of the engine without tearing it apart.
Instructions
If it is unchanged or extremely low, then the engine has worn valves or serious internal damage.
