Dodge 318 Valve Covers are the cheapest, easiest and fastest way to dress up your engine compartment. Fancy valve covers are like six pack abs, you'll always be looking for reasons to show them off. At the very least, you'll smile every time you check your oil; and at the very most, you'll be begging your friends and family to look under your hood at every stop.
Any Small Block Dodge Valve Cover Will Fit The 318 Engine Heads
For decades, Dodge used the same dimensions on its small block engines, known as the "LA Small Block Series." That means that the same valve covers that fit a 318 will also fit the 340 and the 360 engines. Why is this important? Because many manufacturers don't market to the 318 crowd, mostly because the 318 engine was designed as a base model, where the 340s and 360s were the "power" models. In their experience, 318 owners aren't typical engine builders (though there are many Dodge 318 Performance Upgrades to get even more power out of this so-called "base model"), so they laser-target their marketing and labeling to attract the owners of the bigger displacement motors.
Long story short, any valve cover designed for the LA series Dodge small blocks will fit your 318.
Note: For those not familiar with engines and are wondering what the heck valve covers are, they are lightweight "bubbles" that sit on top of the engine heads (there are two heads, hence two valve covers). Other than the air filter and intake manifold, valve covers are probably the most visible parts of your engine when viewed from above.
Now lets get to the good stuff: The various valve cover brands to choose from.
Cheap Dodge 318 Valve Covers
CFS Performance valve covers are available at Amazon and other online retailers.
Edelbrock Dodge 318 Valve Covers
Edelbrocks has built its reputation making quality parts for the high-performance crowd. Their valve covers are built in that same tradition. While valve covers won't affect the performance of your engine (though lighter-weight ones might reduce total weight, thus helping overall vehicle performance), knowing they're made by one of the world's leading aftermarket manufacturers might make some people rest easier.
Plus, they look very cool. And if you're an Edelbrock fan, there's nothing more "showy" than proudly displaying your favorite brand.
Edelbrock valve covers are available at specialty engine shops and boutique auto parts stores.
Mopar Valve Covers
All history aside, Mopar valve covers look great and show your devotion to the Dodge brand. These aren't cheap compared to the budget-priced models I mentioned first, but they look very sharp and come with the added bonus of keeping your engine "Dodge pure." You should be able to pick up some Mopar valve covers for your 318 Dodge engine starting at about $125, but they go up from there.
You won't find Mopar parts at your local auto parts shop. You'll need to order them through your local Dodge dealer or boutique parts shop. They are also available online at places like SummitRacing.com.
Other Valve Covers For Dodge 318
While I've listed some of the most popular Dodge 318 valve covers currently on the market, there are even more choices available, should you choose to keep looking. The reason I haven't listed these is because they are either discontinued, or a variation of what I've already mentioned. For instance, there are several other "generic" brand valve covers for small block Dodge engines, but I chose to list one of the cheapest. I figured that if you're looking for a simple, generic pair of valve covers, you're probably looking for the best price - but know that there are other similar products available for a little extra money (though the looks and performance won't be any better than the CFS products I mentioned.
Other companies have produced small block Dodge valve covers, but have discontinued them, including popular aftermarket companies like Weiand and Holley. If you're interested in one of these brands, you should be able to find a pair of used ones online or in your local wrecking yard.
