Signs you need an Engine Overhaul
What does an Engine Overhaul entail?
Engine Overhaul refers to the process of disassembling, cleaning, inspecting, and repairing all the necessary engine parts to restore it to its original working condition. Depending on what the issue is with your engine, sometimes an overhaul is better than if you would fully replace it. This will save you money as you will not need a brand-new engine for your vehicle.
When your Engine is Overhauled the lower half of the engine is removed and is disassembled and cleaned so that it can be rigorously evaluated. Depending on the condition of the internal parts of the engine, bearings, and piston rings, they may need to be replaced. The internal surfaces of the cylinders are also reconditioned to make sure the piston rings can form a proper seal with the cylinder walls. The engine is then reassembled and installed back into your vehicle. A good overhaul can last a good 5 to 10 years if done correctly.
Reasons and signs you need an Engine Overhaul
If there is any sign of wear to the engine bearings, it is usually best to have an overhaul done. This is also recommended if you have piston rings that are poorly seated. The moving parts of an engine are mounted on bearings, which allow them to move freely as they are lubricated by engine oil. The bearings are built to last over thousands of kilometers, but eventually they will start to wear down. The wear is accelerated when a vehicle is poorly maintained and running low on oil levels. Worn bearings will start to produce a loud knocking noise and will eventually cause the engine to fail. More extreme signs that your engine needs attention are metal shavings in the engine’s oil. Your fuel efficiency will also seem to drop.
Piston rings can also cause issues to your engine if they are not properly maintained. They seal in the expanding cases that are created when the gasoline burns within the engine. As they wear, they no longer can seal the cylinders properly. When this occurs, the crankcase oil escapes past the worn rings and is burned with the fuel mixture that is in the cylinder. This is typically why older engines have an excessive amount of white smoke in the vehicle’s exhaust especially when the vehicle is cold. With all the issues that can happen with your engine, it is wise to always make sure to go to scheduled maintenance service, so your vehicle is running as smoothly as possible.
