The valve cover gasket is one of the most important parts of the engine. Typically made of plastic, rubber, or cork, it acts as a tight seal that prevents oil from leaking into other parts of the engine.
The valve cover gasket is typically seated on the valve cover, so once you find the valve cover, you’ll find the gasket too. On most vehicles, you can usually find the valve cover in between the engine block and cylinder head.
On 2007-2013 Nissan Altima models, you can find the valve cover gasket between the valve cover and the top of the cylinder head. It’s usually in the center of the engine, underneath the positive crankcase ventilation (PCV) hoses, so it should be pretty easy to spot.
Tips on How to Access the Valve Cover Gasket
Accessing the valve cover gasket can be a long and complicated process. Before everything else, you’ll have to remove everything in the way before you can even get to the gasket. On some vehicles, this includes the PSV hoses, spark plug brackets, and a bunch of other wires.
Here’s an extra step most people forget to do: apply silicone on the new gasket. Of course, be sure to check your owner’s manual for specific instructions from your manufacturer since not every vehicle needs this.
