The compression test can inform you if you have low compression in your car engine caused by leakage of worn piston rings, defective valves and seats, or maybe you have a blown head gasket or cracked cylinder head.

Connect your compression gauge to the various cylinders, one at time by fitting and screwing the connector into the spark plugs hole. Before you do compression test ensure your car battery is fully well charged to ensure a sufficient engine rotation speed.

Do You Need An Auto Engine Repair If The Compression Is Low

car engine overhaul If the compression reading for the various cylinders do not differ by more to 10% of the maximum reading it is considered that all the cylinders are in the same condition is no need to an auto engine repair. On the other hand if one or more cylinders the compression reading is low the above minimum you need to find out the reasons. The reasons can be the valve seating and proceeding to an inspection of the compression rings and the pistons themselves. In this matter now your car need an auto engine repair.

What An Auto Engine Repair Mean To You

Engine Piston

Piston Ring Failure – Causes and Prevention

One of the major complaints that I have heard from many mechanics, and engine technicians, is that piston rings in heavy duty tractor engines wore out prematurely. I have heard this complaint many times. As per normal human responses, there is a quest to rationale the reasons as to why this component failed, as per the complaints from those in the field.

Not surprising, complaints of piston ring failure are blamed on the manufacturer of the rings. It’s not unusual to hear “Do not use these types of rings” and specific manufacturers are mentioned. However, I have heard these complaints about rings from OEM companies as well.

 My analysis led to several pertinent discoveries, especially after a particular customer asked for Original Caterpillar Piston Rings, not the rings presented to him. Little that that customer knows that the rings presented to him were manufactured by the same company that is on contract for Caterpillar. The first mistake that is made that contributes to major ring failure, is the seemingly economic benefit, of changing the piston rings only, however, the piston pin, piston pin retainer, and the cylinder liners are left in the used condition. These reused parts have clearances due to normal wear on the metal parts that contributes to slight but permanent vibrations within the entire engine. These almost invisible vibrations will lead to premature wear on all components, and most importantly, to the vibration of the rings on the piston head.

An engine with a 2800 rpm rating, with minor vibrations at that high speed, will have additional stress and strain on internal engine components. Other than the vibrations mentioned above, the used cylinder liner itself is damaged, with microscopic indentations, scratches, and worn out sections. This contributes to an uneven surface that the new piston rings have to move up and down in at 2800 rpm.

It’s this phenomenon that contributes to premature ring failure. Piston rings from original companies like Caterpillar and Cummins, will fail prematurely in this situations. Aftermarket piston rings from other reputable companies will fail prematurely in these situations. The problem is in reused cylinder liners, and not piston rings.

It’s not unusual therefore, that both OEM and aftermarket companies do not provide a warranty for rings that were changed without also changing the other internal components, namely the cylinder liner, piston, piston pin, and piston pin retainer.

While specific company warranty applies, most of them will consider this practice as voiding the warranty. The recommended thing to do, even though it’s a little more expensive, is to change all of the liner kits at the same time. Its more work, it’s a little more money, however, the results are better engine performance, less breakdown possibility, less fuel consumption, less pollution and GHG emissions, and the most important part, more peace of mind for the owner/manager.
