Is It Time For Your Automobile Engine To Be Rebuilt?

Individuals who aren't auto repair specialists have likely heard about an engine rebuilt, but they are not entirely sure why or when it may be needed. Below, you will learn why your engine may need to be rebuilt, the signs that it is time for an engine rebuild, and how much it is going to cost you.

2 Main Reasons Why Your Engine Needs Rebuilt

Overall, there are two primary reasons that you need to have your engine rebuilt: engine bearing wear and piston rings that are poorly seating.

Engine parts, like the pistons, rods and crankshaft need to be able to move freely. They're mounted on the engine bearings, which receive lubrication from the oil inside the engine. Over time, these bearings will experience wear and tear. This is particularly true when oil changes aren't performed as instructed by the manufacturer. When bearings become worn, they will typically cause a loud knocking sound coming from the engine. If left undiagnosed and untreated, it can lead to critical failure of the motor.

As for the piston rings, they help to keep the gasses sealed that are created from the engine burning gasoline. When the pistons begin to experience wear, they can't properly seal the cylinders. This results in what is known as a "blow-by," which occurs when there is an explosion within the motor's combustion chamber. This then causes a mixture of moisture, air and fuel to escape past the piston rings. This can result in contamination of the oil and the loss of horsepower. It may also cause white smoke to come out of the exhaust.

How Do You Know When It's Time for A Rebuild?

Most frequently, you are going to notice that your engine is using a lot more oil than usual. You may check it and top it off on a Monday, and by Friday, the engine will be a couple of quarts low (give or take, depending on how severe the damage is). You may also notice white smoke coming from your vehicle's exhaust. This is particularly true before the engine has time to heat up. If you change your own oil and notice that there are metal shavings in it, then this is a very serious and time-sensitive sign that the bearings are gravely worn and need to be repaired.

How Much Does It Cost to Have an Engine Rebuilt?

The cost of engine rebuild is going to depend on a number of factors, including the type of car that you own and your location. However, as a general rule, you are going to be looking at spending somewhere between $2,250 and $4,000.

A rebuild isn't always the answers. If you experience any of the above signs, you will want to take your vehicle to an auto repair shop, like Dugan Oil and Tire, to have it checked out.
