  • How to Determine Apparent Jeep Liberty Engine Failure

    Have you been counting miles with your Jeep Liberty? Do you think it will still go farther with a reliable engine, or is it starting to show signs of failure? The possibility for the latter to happen is as great as the first one, depending on how diligent you are with your vehicle\'s maintenance regimen. Remember that even minor leaks lead to major problems that can eventually end to engine failure. And so, it will be wise to closely watch engine problems, and immediately determine if they are caused by any problems other than internal engine damage that requires major repair.

    Troubleshoot engine problems

    The point of troubleshooting is to find the cause of an engine problem in order to give the required solution. The reason behind is that different engine problems are indicated by several similar symptoms, such as unable to start despite normal cranking, poor fuel mileage, rough idling, running roughly at low speeds, misfiring at high speeds, surging at steady speed, lack of normal power, poor acceleration, abnormal vibrations, and overheating to name a few.

    Test engine compression

    Testing engine compression is basically determining whether the internal engine parts, such as the pistons, piston rings, valves, and cylinder head gasket, are in good condition or if something is worn or broken. This is necessary because you might be giving incorrect solution to a wrong problem, unknowingly leaving the real problem behind and letting it worsen up to the point that even a tune-up would do no good.

    The process requires the engine to be hot, the throttle wide open, the battery fully charged, and the oil reaching the \'Full\' mark on the dipstick. You have to remove the air cleaner, spark plug cables, and the ignition cable. Ensure the engine is off by grounding the ignition cable. Also disconnect the main multi-wire harness connector found on the side of the distributor cap tagged BAT. Before removing the spark plugs to give way for the compression gauge, make sure that no dirt will be able to escape into the combustion chamber. The gauge would read accurately if the engine makes 4 to 5 revolutions for each cylinder. If any two cylinders read below 20 psi, another set of readings should be done after squirting engine oil into the spark plug holes. Note that compression testing with cold engine requires manually opening the throttle and choke plate and then holding them open with wedges.

    Analyze compression readings

    High reading would mean excessive carbon buildup inside the engine or that the exhaust valves are not fully opening to allow complete emission of carbon. Meanwhile, if readings in one or more cylinders or in the two adjacent cylinders are at least 20 psi below, confirm any internal problems by running another set of readings. Higher readings in the new set mean worn piston rings. If they stay almost the same as the first readings, the engine has worn valve seats or sticking or burnt valves. Now, if the two adjacent cylinders\' compression reads below 20 psi as against the others, the head gasket between these two is damaged. Your engine is failing and needs repair.
