When Should You Overhaul Your Car Engine?
An engine overhaul is not something you do regularly. Usually, you do this when there is a major problem with your car’s engine. Engine overhaul can also be done on a worn-out engine with higher mileage to restore it to its original condition.
An engine overhaul may be necessary if you have an older car. If your vehicle is over ten years old and it has racked up a lot of mileage, you should consider overhauling the engine.
Signs You Should Consider Overhauling Your Car Engine
When you notice some things with your car, it could mean you need to overhaul your car engine. Signs you include the following;
White or Black Exhaust Smoke
White exhaust smoke could mean the piston rings are worn-out or broken. It could also mean the engine oil has entered the cylinder and burned with the air-fuel mixture during combustion. On the other hand, black smoke is caused by carbon buildup on the pistons and intake valves.
Frequent Engine Overheating
Another sign that could mean it is time to overhaul your car engine is if your engine is frequently overheating. Overheating could mean there is a leak in the radiator. Overheating could also be caused by a faulty gasket.
Excessive Engine Oil Consumption
When you start topping up your engine oil many times, it could mean there is a leak in the engine. It could also mean the piston rings are damaged or worn out.
Strange Engine Noises
It is not a good sign when you hear strange noises from the engine. Rattling sounds, for example, could indicate the piston rings are broken. It could also mean the engine mounts are worn-out. On the other hand, knocking sounds might mean there is too much clearance between the piston rods and the crankshaft.
