HHP Spotlight: Rocker Cover Gaskets

If you’ve noticed a leak in your engine, or you’re just replacing your injectors, you should probably take a look at your rocker cover gaskets. If you’re working on your injectors, it’s a good idea to replace these gaskets as well, while you’re in there.

We recently did a blog and video on the line of PurePower injectors we carry, bringing the OEM quality to the aftermarket. Well, we’re expanding on that today with our offerings of rocker cover gaskets.


As we mentioned, if you’re going in to replace your injectors on your diesel engine, it’s a good idea to replace your rocker cover gasket. We’ve got ‘em available for you!


We have the gasket for the 6-liter Ford. It’ll come with one rocker cover gasket, as well as the associated grommets you need to complete the job. They’re sold individually, so if you’re only doing one side, you can get one, or if you’re doing both sides, order up two.


We also have one for you all with the 7.3-liter. 7.3’s have actual wiring harness throughout the valve cover gasket, so it’s a good idea to replace those while you’re in there. This gasket is also going to come with an external harness, so you can wire up a new connection while you’re in there. These are also offered individually, so if you’re only doing one side, you can order them one at a time. But, if you’re doing all eight, you can order two and that’ll get you taken care of.

It’s a good idea to take care of your rocker cover gaskets while you’re already in there doing the work to help ensure you don’t have any leaks moving forward.



Replacing your rocker cover gasket is a job often done at the same time you’d replace your fuel injectors. 


If you’re wondering if you have a faulty injector, there are a few ways you can identify which might be failing. First, you can obviously have your mechanic diagnose the issue if you don’t feel like this is something you want to take on yourself. You can listen to the injectors (not getting your head to close to the running engine). You can also use a test light to see which injector is not operating correctly—a functioning injector should light the test light. A multimeter can be used in a similar way to see which injector isn’t being powered. An infrared thermometer can help as well. A functioning injector should be warmer than one that isn’t. You can also check for obvious visual indicators of a failing injector, like leaks or broken seals.
