Are you contemplating an engine overhaul? It could be your vehicle has high mileage and you are concerned about its declining performance. Below is a short guide on the various considerations you should make when conducting engine overhauls.
Top Signs That You Need an Overhaul
Below are a few reasons to get an engine overhaul:
- If you intend to boost your engine performance by replacing OEM injectors, pistons, crankshafts and cylinders with aftermarket performance parts.
- Chronic overheating problems could lead to wrapped cylinders and damaged gaskets, so your engine will need an overhaul.
- Strange sounds from the engine are an indication of worn bearings and pistons.
- If your engine produces a thick, blue-black smoke, piston rings could be damaged and leaking oil into the combustion chamber. As such, you may need an overhaul.
- Metal chips as you replace the engine oil are an indication of severe wear of internal engine components.
Work With a Specialised Mechanic
Engine overhauls are a complex and delicate task. As such, work with a mechanic specialising in your type of vehicle. If you own a classic car, conduct some research to determine the availability of spaces. In some cases, you may opt to replace the engine.
Determine the Scope of the Overhaul
Your mechanic will remove and disassemble the engine. He or she will begin by inspecting external components such as the serpentine belt, pulleys and alternators. Other considerations include:
- Worn-out connecting rods and pistons will need replacement.
- If the cylinder bores are worn out, you may need to replace OEM cylinders with aftermarket ones.
- A bent crankshaft can be repaired. You will need a new one if you notice cracks or severe wear.
- Check the condition of engine bearings and determine the need for replacement.
Use a sponge, warm water and soluble detergent to get rid of old oil, grime and carbon deposits on the various engine components. Engine overhauls are an opportunity to change the gaskets, oil seals, plugs and piston rings. Check the mileage of parts such as the timing belt and the water and fuel pumps. Besides, conduct major service by changing the oil (never attempt to reuse old oil), fuel filter and air filter. Moreover, clean the radiator if it has been in use for many years. Finally, clean the engine bay before connecting the engine.
An engine overhaul will help improve your car's longevity. Working with an experienced mechanic will ensure the process is a success. Contact a company that offers engine repair services to learn more.
