A »To perform a compression test, remove the spark plugs, screw in a compression gauge, and crank the engine. Compare the readings across cylinders. Low compression indicates worn piston rings or cylinder walls, while inconsistent readings suggest valve issues. High compression indicates carbon buildup. Results help diagnose engine problems and guide repairs.

A »To perform a compression test, remove the spark plugs, insert a compression gauge in each cylinder, and crank the engine. Ideal readings are around 100-200 psi. Consistent readings across cylinders indicate a healthy engine, while low or uneven results may suggest issues like worn rings or valves. Always consult your vehicle's manual for specific guidelines and safe practices!

Low compression indicates worn piston rings or valves, while inconsistent readings suggest uneven wear. High compression with oil added indicates worn rings, while no change suggests valve issues.
