No energy source in the world is more sought-after than oil. Car owners should treat their engine's oil with as much importance. It's the only thing keeping the engine working despite extreme heat and pressure conditions in the engine bay.You should also make sure the oil filler cap is intact and leak-free. The cap fits the oil tank as a covering for the hole into which engine oil is poured. The cap also serves as a release valve to prevent pressure from building up under the valve cover.There have been a lot of cases when car owners and mechanics alike have forgotten to reinstall the cap after changing the engine oil. This leaves the engine open to all sorts of dirt and moisture in the air and exposes oil to contaminants as well.If your car's stock oil filler cap is full of carbon deposits, you may want to replace it.

How to Maintain an Oil Filler Cap
Anything that holds liquid should come with a cover to keep its contents from spilling. Without a tight seal, leaks and spillage abound. The same goes with your valve covers. Under your hood, it is your oil filler cap's job to keep oil and fuel from drenching important parts of your engine compartment. So to avoid blowing off an engine rod or other similar damage to your engine, always make sure that the oil filler cap is clean and tightly sealed.
Difficulty level: Easy
Tools you'll need:
- Oil filler cap
- Oil filler cap gasket
- Clean rags
Step 1: Locating the oil filler cap
To locate your oil filler cap, open the hood of your car and go to the driver's side valve cover. In some cars, the oil filler cap is labeled as "Engine Oil." But if you still can't find it, it's basically the twist cap covering the side valve cover.
Step 2: Removing the cap
After you've found the filler cap, grasp and rotate the cover counter-clockwise to free it from the valve cover. If the cover's too tight you can use a clean rag or a wrench to twist it off. Be careful when turning the cover, especially when using a wrench. Don't put too much pressure to avoid denting or chipping.
Step 3: Cleaning the oil filler cap
Take out the oil filler cap from the hole and examine it. Wipe it with a clean rag to remove any oil and dirt.
Step 4: Replacing the oil filler gasket
If your oil filler gasket has been worn out, replace them before putting back your filler cap.
Step 5: Reinstalling the cap
Place the oil filler cap back on the valve cover. Twist it clockwise to reseal the valve cover with the cap.
Step 6: Test-driving the replaced cap
Close your hood and you're ready to test-drive your new oil filler cap.
