Is your Challenger leaving its mark?
A leaking valve cover gasket is one of the most common oil leaks on any engine, including the Mitsubishi-built 2.6L 4-cylinder in your 1981-1985 Dodge Challenger. Over time, the original gasket, likely made of cork or rubber, gets hard and brittle from engine heat and age. This causes it to shrink and crack, allowing oil to seep out.
Symptoms of a Failing Valve Cover Gasket
Catching a bad gasket early can save you from bigger messes and potential problems. Here’s what to look for:
- Burning Oil Smell: This is the most obvious sign. Oil drips from the leaking gasket onto the hot exhaust manifold, where it burns off and creates a distinct, unpleasant smell that you might notice inside the car.
- Visible Oil and Grime: Look at the seam where the metal valve cover meets the engine head. You will likely see wet, oily patches or a buildup of thick, greasy dirt where the oil has leaked and collected road grime.
- Low Engine Oil: A persistent leak will cause your engine oil level to drop over time. You might find yourself needing to top off the oil between changes.
- Rough Engine Performance: In some cases, oil can leak into the spark plug tubes. This can foul the spark plugs, leading to engine misfires, a rough idle, and poor performance.
A Note on Your Vehicle's History
Remember, the 1981-1985 Dodge Challenger is a rebadged import, built by Mitsubishi. It shares its 2.6L engine (often called the G54B) with vehicles like the Plymouth Sapporo and Mitsubishi Starion. When searching for parts or repair advice, using these names can sometimes yield more results.
Choosing the Right Aftermarket Gasket
For a vehicle of this age, finding original equipment (OEM) parts from a Dodge dealer is nearly impossible. The aftermarket is your primary source. While the prompt mentioned Victor Gaskets, it's important to know about all your options.
- Victor Gaskets (Victor Reinz): This is a widely available aftermarket brand. However, owner experiences are mixed. Some mechanics and DIYers have reported success, while others have faced issues with gaskets leaking shortly after installation or having a poor fit that makes installation difficult.
- Fel-Pro: Another major aftermarket gasket manufacturer, Fel-Pro, also produces a valve cover gasket set (Part No. VS 50146 R) for this engine. Fel-Pro is often well-regarded in forums for its quality and reliability.

Frequently Asked Questions
Is this a difficult job to do myself?
No, for most DIY mechanics, this is a very manageable job. The 2.6L engine offers good access to the valve cover. The repair involves removing a few bolts, cleaning the surfaces, and installing the new gasket. It typically takes 1-2 hours and requires basic hand tools.
Do I need to use sealant with the new gasket?
Generally, modern rubber gaskets are designed to be installed dry. However, it is standard practice to apply a small dab of RTV silicone sealant at the corners or sharp bends, especially where the engine timing cover meets the cylinder head, to prevent small leaks in these critical areas. Always check the instructions that come with your specific gasket set.
Is a small valve cover leak a serious problem?
A small seep is not an immediate emergency, but it should not be ignored. The dripping oil can damage other rubber or plastic components, creates a fire hazard if it drips on the exhaust, and makes a mess of your engine and driveway. Fixing it is cheap and easy, so it's best to address it sooner rather than later.
Are there any recalls or TSBs for this issue?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls or Technical Service Bulletins (TSBs) related to the engine valve cover gasket for the 1981-1985 Dodge Challenger.
