Message: <blockquote data-quote="vr2turbo" data-source="post: 1063893064" data-attributes="member: 92229">You are welcome. Just some basics on the compression test...1Prepare for the test by warming up the engine. The battery must be in good condition since it will spin the engine quite a few times. Testing a cold engine will give inaccurate readings.2Stop the engine and remove the spark plugs so that the starter can spin the engine freely, and then disable the ignition system. To do this, either pull the coil wire or disable the ignition coil.3Insert the compression tester into one of the spark plug holes and crank the starter to rotate the engine. This builds compression in that cylinder. Move on to the next cylinder by removing the compression tester and inserting it into the next spark plug hole, repeating this procedure until you test all the cylinders.4Record the compression number for each cylinder and compare them. The numbers should be about 10 PSI of each other and match up with manufacturer's recommendations. If one or more of the cylinders shows a difference of 15 or more PSI, a problem exists.5Remove the compression tester and add a small amount of motor oil to the cylinder that showed a low reading. Run the compression test again to test the piston rings and cylinder walls for wear. If the second compression number is higher than the first, the problem lies here. If it stays the same or is very low, the problem is more than likely due to worn valves or serious internal damage.Read more: How to Test Car Engine Pistons | eHow.com <a href="http://www.ehow.com/how_4486234_test-car-engine-pistons.html#ixzz1nllmYYm5" target="_blank">How to Test Car Engine Pistons | eHow.com</a></blockquote>
