What Causes An Oil Leak

To know how to fix an oil leak, you must first diagnose the problem-what causes an oil leak in the first place.

Here are some common causes of oil leaks in a vehicle:

  • Faulty oil filter
  • Damaged gasket or oil pan resulting in oil leak after oil change
  • Defective installation resulting in oil leak after oil change
  • Improper valve rings
  • Damaged filler cap
  • Overfilling of oil

The cause of the oil leak is essential to diagnose. For example, an oil leak after oil change could mean a damaged gasket, meaning you need to repair your gasket.

Let’s go over how to fix an oil leak.

How To Fix An Oil Leak At Home?

Here are our top tips for fixing an oil leak:

Use An Oil Leak Stopper

You can use a product like Bar’s Leaks to prevent oil leaks from recurring in your car. Apply the product to the leaky area, let it dry for several hours, then drive your car for a few days to see if there is any improvement.

Use A Mechanical Sealant To Fix An Oil Leak

A mechanical sealant is a substance that fills the gap between two surfaces, preventing oil or other fluids from coming out. You can use it to fix an oil leak in your car’s engine, but it’s also helpful in resolving other problems.

Mechanical sealants come in many forms: they can be liquid or solid and are commonly used with tape or as glue. You’ll want to find one that matches the type of material where you’re applying it so that it doesn’t leave any residue afterward when you remove it (and so on).

Use A Gasket Sealer To Repair An Oil Leak

Gasket sealers are a great option if you don’t have access to the necessary tools or equipment, but they’re not always ideal.

If you’re looking for a way to repair your oil leak without having to go through the hassle of hiring someone, consider using gasket sealer spray instead.

Check The Valve Stem Seals On Your Car’s Engine

Here are the steps to follow for damaged valve stem seals causing oil leaks:

  • Check the valve stem seals on your car’s engine.
  • If you have an oil leak, replace the valve stem seals.
  • If they’re worn or damaged, replace them.
  • If they’re leaking, replace them.
  • And if they crack and let oil escape into your engine compartment (aka leakage), we commend taking it to an expert mechanic who can fix this problem for you!

Fixing A Leaking Head Gasket

The head gasket is the part of your engine that seals the oil from entering your engine. If this seal is damaged, you’ll see oil leaks.

To fix a leaking head gasket, you need to replace it with new parts. You will need to buy a new head gasket sealant (this is usually found in auto parts stores or online). You can also use another type of sealant, like silicone-based ones, if you don’t want something too thick or goo-ey looking on your car’s exterior.

You’ll also need to buy some new head gaskets if they are worn out or have been broken into pieces over time due to age and wear (they’re expensive, though, so make sure yours hasn’t been damaged).

Now that you know how to fix an oil leak, let’s find out the answer to how much does it cost to fix an oil leak?

How Much Does It Cost To Fix An Oil Leak?

As explained earlier, there is a wide range of sorts and locations in your car that it may impact. Therefore, the sooner you take care of the issue, similar to most auto repairs, the better off you’ll be and the more cash you’ll save.

So, how much does it cost to fix an oil leak?

Early Fixing

Early detection of an oil leak in your car will result in minimal expenditures. Your dealer or specialist will most likely need to repair the damaged components, such as oil seals or gaskets. These things cost between $5 and $10 each and are reasonably priced and accessible. It might be a bit higher if you factor in labor costs, but that depends on your situation.

Late Fixing

You will have to pay a higher cost if you wait till later. Additionally, it relies on whatever component of your car is most damaged. You can be looking at several thousand dollars if the problem is with the engine.

If it’s the radiator, it might cost you less, but it won’t be less than $300. You might need to order and replace a whole part, resulting in a higher cost. After accounting for labor costs, you’re left with a hefty payment that could be challenging to pay.

Even though the expense of repairs may seem prohibitive, your technician will do a careful leak check and give you a complete report outlining the necessary work and associated costs. They might advise doing more work, such as a full oil change, which would increase the price.

Significant repairs are less likely to be necessary if you maintain the engine properly and change the oil frequently. Regularly investing a small sum of money in this maintenance will help you avoid unnecessary headaches on how to fix an oil leak.

As with learning any repair work, whether it be how to fix an oil leak or the humming sound in your car, it’s essential to do your research and find the right solution for you, as there are many different types of leaks and each one will require a different repair method.
