Express Auto Service & Repair

You’ve taken your car to your auto shop for a routine engine service. You get the bad news—you need an engine rebuild! Most people have heard of an engine rebuild but not many really know what rebuilding an engine consists of and why it is necessary.

There are two main reasons for an engine rebuild: worn engine bearings and poorly sealed piston rings. The moving parts of the engine (such as the crankshaft, rods, and pistons) are mounted on bearings lubricated by the engine oil, allowing the engine components to move freely.

Worn bearings produce loud knocking noises and eventually can cause failure of the engine. Although bearings are built to last thousands of miles, they do experience wear after time. This wear is accelerated exponentially when a vehicle is not maintained properly and is run on low oil levels or dirty oil.

Piston rings seal in the expanding gasses created by the burning of gasoline within the engine. As piston rings wear, they no longer seal the cylinders properly, resulting in a phenomenon called "blow-by.” Blow-by occurs when crankcase oil escapes past worn rings and is burned with the fuel mixture in the cylinder. Often this is the reason that older engines have an excessive amount of smoke in the exhaust.

You may be wondering what happens during an engine rebuild. First, the "short block" or lower half of the engine is removed, disassembled, and then cleaned so that the condition of the block can be properly assessed. Depending on the condition of the internal parts of the engine, the piston rings, bearings and sometimes the pistons themselves are replaced. The internal surfaces of the cylinders are also reconditioned to ensure that the new piston rings can form a proper seal with the cylinder walls. Finally, the engine is reassembled and installed back in the vehicle. The cylinder head may also be reconditioned at the same time.

So what are the benefits of an engine rebuild? First, you know that everything has been closely inspected and now has new parts. Second, the engine parts are being recycled to help reduce the amount of scrap in the environment. The third, and the best, benefit is the connectivity and compatibility with the existing ECU and electrical system.
