Owing to it entered the bazaar, the engine in the Mitsubishi has changed many times. Regardless of if the vehivle is a four-cylinder or V-6 engine, it is crucial that you detain it running properly. Parts wear absent over interval, which can basis the engine to burn oil. A light compression test is an inexpensive street of determining problems in the engine without evil the engine.
Instructions
1. Close up the engine in your Mitsubishi. Running a compression comp on a arctic engine Testament not practise accurate findings. Make certain that the battery is in deluxe shape, as you Testament demand it to spin the engine multiple times during the catechism.
Compare the compression numbers you wrote down to the recommended Mitsubishi compression ratios.5. Analyze the compression numbers to make certain that they are within 10 PSI of each other. Perform the test again on any cylinder with a low reading after adding a little bit of motor oil to that cylinder.
3. Put the compression tester in one of the spark plug holes and then crank the starter. This prompts rotation of the engine and will consequently build compression in the cylinder. Write down the compression number and move on with each spark plug hole. Record all of the compression figures.
4.2. Remove the Glimmer plugs from the engine, and disable the ignition method to prevent electrical shock. Whether the motorcar has a four-cylinder engine, there Testament be four Glimmer plugs (a V-6 Testament admit six Glimmer plugs). By removing the spark plugs, the engine will now spin unhindered.
If the new compression number reading increases, this is indicative of worn piston rings or cylinder walls. If the number does not change, the problem lies in worn valves or valve seats.
