Ask any owner about a common engine problem that has a direct relation to vehicle mileage. He’ll say it is oil leaking without a second clue. Oil leaking reduces driving taste, enhances vehicle maintenance costs, pollutes nature and finally pushes your vehicle to deep problems.

Every vehicle, from car to Jeep, pickup to Tractor, faces this problem like a curse, and it doesn’t matter whether it is new or old. 

As a luxury vehicle, a Jeep owner suffers the most if the vehicle has any leaking issue. Today I will talk about Cherokee leaking problems that might help your Jeep to get better mileage.

If your jeep Cherokee oil leak from the engine or fuel tank, you will face all the problems that I said in the beginning. You will suffer the most from the jeep leaking issue when traveling in an offroad area near Utah or Michigan. 

A brief overview:

Faulty oil filters, broken oil pan, valve cover gasket, and oil drain plug problems are the main causes of oil leaking in your Jeep Cherokee.

Experts also say that faulty installation and using polluted oil are also responsible for oil leaking in your vehicle. I have said everything in detail with proper solutions that may make the process easier.

Why Is Jeep Grand Cherokee Leaking Oil?

1. Oil Filter Problems

Oil filters play a major role in keeping a vehicle’s engine active and long-lasting. When you pour oil on the tank, it doesn’t go to the engine directly. Oil needs to be purified from some additional contamination, and an oil filter does the work perfectly. 

If there are any wrong chemicals, dust, or small metal parts mixed with oil, oil filters detect them and keep them away from pure fuel.

But, the whole process becomes abortive when oil filters fail to perform. When your jeep oil filter is faulty, you will find a lot of problems, from fuel leakage to engine failure. 

2. Broken Oil Pan 

Have you given a closer look at the Jeep’s oil pan under the engine? Is there any holes or scratch on that spare tank? The oil pan works as external storage where all additional pure oil takes a rest that is not needed for the engine. 

When you are using some older jeep Cherokee like XJ or ZJ, maybe the oil pans are damaged or abortive. As it is situated on the lower side of the engine, there is a chance that it could be hit on an off-road.

Issues with an oil pan are quite usual, and there are several causes behind it that may lead to oil leakage on your jeep wrangler or Cherokee.

3. Valve Cover Gasket Issues

Valve cover gasket is a trusted engine component to protect engine parts and constant oil flow in the engine. When your Jeep is leaking oil, this major engine component could be a related cause of oil leaking. 

This is made of pure solid metal, and there are a couple of holes with caps to protect the engine. Though it can tolerate much pressure and heat, sometimes it is so vulnerable that you need to drive your Jeep with bad piston rings and oil leakage.

4. Wrong Installation Or Fitment

Naturally, we try to install something newer, from Jeep lowering to swapping diesel engines. However, we forget about fitment without any reason. have you recently changed any parts related to fuel in your Jeep Cherokee?

Maybe changed parts are not well installed, and you are getting some fuel issues. 

After a long time driving on your Cherokee, like 3 to 5 years, it makes engine and fuel components slightly disabled. If you are one of those who drive Cherokee without regular maintenance, you might find some oil leaking issues. 

5. Using Poor Oil

There are different oil in the various fuel stations to use in your jeep Cherokee or wrangler. Usually, we take fuel from the station that is closer to our home without thinking about the vehicle’s safety and performance. 

When we use polluted oil in our Jeep regularly, most of the time, the engine function fails to perform well. It enhances engine heating and sometimes makes leakage inside your Jeep. It makes different fuel parts like oil pans or oil filters weak and rusty, which can lead to oil leaking. 

6. Faulty Oil Drain Plug

Sometimes an oil drain plug is considered one of the popular causes for oil leaking on your Jeep. If you have any fueling issue related to a drain plug, it is not a matter of extra headache.

Because you can easily replace it with a minimum budget of $20 to $30, and you also don’t need an expert if you have previous working experience in the fuel industry.

  • As most of the time, oil leaks from the valve cover gasket, you should check this engine component from time to time. There are multiple holes available in the gasket, and if the leakage is from there, fix it with melted metal or use any powerful seal kit.
