Is Your Cherokee Leaking Oil? It's Probably the Valve Cover Gasket
One of the most common issues on the 1997-2002 Jeep Cherokee XJ is an oil leak from the engine valve cover gasket. Fortunately, it's a relatively easy and inexpensive problem to fix. 🎬 Watch this step-by-step walkthrough of the gasket replacement process. If you notice a burning oil smell or see oily grime on the side of your engine, this guide will walk you through choosing the right aftermarket replacement part.
Symptoms of a Failing Valve Cover Gasket
A bad valve cover gasket will give you a few clear signs. The most common one is a burning oil smell, especially when you are stopped at a light. This happens when oil drips from the leaking gasket onto the hot exhaust manifold below. You may also see:
- Visible Oil and Grime: A buildup of oil and dirt on the driver's side of the engine block, just below the painted valve cover.
- Drips on the Ground: Small spots of oil on your driveway.
- Low Engine Oil: Having to add oil between oil changes.
- Smoke from Engine Bay: In more severe cases, you might see light smoke as oil hits the hot exhaust.
Pro Tip: Check the Back First! Leaks on the 4.0L engine often start at the rear of the valve cover near the firewall, where they are hard to see. Oil runs down the back of the engine and can be mistaken for a much more serious rear main seal leak. Always clean and check the valve cover area before assuming a worse problem.

For a part like this, a high-quality aftermarket gasket is often just as good, if not better, than the original. Many original gaskets were made of cork, while modern replacements use superior silicone materials. Here’s a look at the brands available:
- Victor Reinz: This is a premium aftermarket brand, often considered OEM-quality. Victor Reinz gaskets are known for their excellent fit and durable materials, making them a reliable choice for a long-lasting repair.
- Apex: This is a budget-friendly option. While functional, the quality can be inconsistent compared to premium brands. It can be a good choice if the price is a major factor, but for a critical seal, spending a little more on a higher-tier brand is often worth it.
When buying a kit, make sure it includes the bolt grommets. The small rubber grommets that seal the valve cover bolts also get hard and brittle and are a common source of leaks. A complete kit should include the main gasket and all the bolt grommets.

Frequently Asked Questions (FAQ)
Is this a difficult job to do myself?
No, this is considered a beginner-friendly DIY job. The most difficult part is reaching the bolts at the very back of the valve cover against the firewall. You will need basic hand tools, a torque wrench, and a few hours.
Do I need to use RTV sealant with the new gasket?
Generally, no. High-quality rubber or silicone gaskets are designed to seal by themselves. However, many mechanics put a small dab of RTV sealant at the four corners where the gasket makes a sharp turn, just as a precaution. Do not coat the entire gasket with sealant.
Should I replace anything else at the same time?
Yes. While the valve cover is off, it is the perfect time to replace the CCV (Crankcase Ventilation) elbows and their grommets located at the front and rear of the valve cover. These plastic and rubber parts get brittle and are another very common source of oil 🎬 Watch a pro replace the gasket and PCV valves together. and vacuum leaks.
What is the correct torque for the valve cover bolts?
The torque specification is very low, around 85 inch-pounds (which is just over 7 foot-pounds). It is very important not to overtighten the bolts, as this can warp the cover or damage the new gasket, causing it to leak again.
