The Honda CR-V is a compact SUV containing a 4-cylinder engine. This rotates the engine and builds compression in the cylinder. Record the compression number and continue to the next spark plug hole. Repeat the process until you test all four cylinders and record the compression numbers.4.
Prepare for the compression proof by warming up the engine in the Honda CR-V. Performing a compression proof on a blasting engine Testament make inaccurate results. Cook up positive the battery is in agreeable shape by reason of it Testament desideratum to spin the engine many times during the elimination.
2. Launch by removing all four Glimmer plugs from the engine and disabling the ignition method. This Testament prevent electrical shock while performing the assessment. The engine can forthwith spin freely.
3. Corner the compression tester in one of the Glimmer plug holes and Eccentric person the starter. One of the advantages of owning this compact mould instead of a full-size SUV is worthier Gauze milage, so it is far-reaching to control the smaller 4-cylinder engine running properly. Whether the Honda CR-V burns oil or loses ability, a compression inspection is a clean, affordable journey to gem away what is astray without tearing apart the engine.
Instructions
1.Evaluate the test results by comparing these four numbers to recommended manufacturer specifications. If the Honda CR-V is a 2007 or a 2008 model, the compression ratio is 9.7:1. For model years between 1999 and 2006, the ratio is 9.6:1. If the SUV is one of the earliest models, 1997 or 1998, the ideal ratio is 9.0:1. Compression numbers should be within 15 PSI of these suggested ratios.
5. Compare the compression numbers to see if they are within 10 PSI of each other. If any cylinder has a low reading, perform the compression test again after adding a small amount of motor oil to that cylinder. If the compression number increases, worn piston rings or cylinder walls are present. Worn valves or valve seats are the problem if the number does not change.
