Do you need to replace valve covers on a Nissan Frontier?
I would at least get the gaskets for the VTC actuators, which have to be removed to remove the valve covers. The gaskets on the upper plenum are silicone, so are technically “re-usable,” but if they have 100,000 mile plus, I would replace them as they do tend to flatten out over time.
How long does it take to replace a gasket on a Nissan Frontier?
The passenger side wasn’t too bad, I think it took me around 2.5 hours. The drivers side was horrible, there was a hose behind the plenum intake manifold that took me forever to disconnect because it was baked on from 14 years of driving and is extremely hard to reach with adult size hands.
Why is the gasket on my Nissan Frontier discolored?
My theory is that the majority of oil pools in that area and gets hot, therefore causing the discoloration. Others have said that the valve cover bolts do not have to be very tight and they are right. I tightened mine down until they felt snug, but did not over-tighten and its holding up fine.
How long does it take to remove coolant hose from Nissan Frontier?
Here are some notes about this job that I am listing from memory. 1. Took me about 2 hours to remove that one coolant hose in the back of the plenum. I had to take the hood off and sit on the windshield and just keep scraping and pushing on that @#$%ing hose until it finally came off.

What causes a plenum on an intake manifold?
Helmholtz Resonance Intake manifold runners take advantage of the Helmholtz Resonance phenomenon, which results in air resonance in a cavity, such as the plenum. When a valve closes, air outside of the valve compresses against it, created a pocket of high pressure.
When to replace the gasket on the upper plenum?
The gaskets on the upper plenum are silicone, so are technically “re-usable,” but if they have 100,000 mile plus, I would replace them as they do tend to flatten out over time. It’s also a good time to replace the spark plugs, if do, or, install an XTP plenum spacer, if you’re considering it.
Do you have to change valve cover gaskets?
Use insulating tape to cover the exposed service plug socket. You may or may not have to do this step depending on how your particular car has its engine oriented in the engine bay.

Where does the valve cover gasket go on a car?
The valve cover sits atop the cylinder head, and the valve cover gasket is sandwiched between them to keep circulating oil inside.

Can a car be driven with a leaking valve cover?
A vehicle can still be driven with a leaking valve cover, but the leaking oil will cause other problems over time. Spark plug wells can fill with oil, causing a misfire. Oil dripping on coolant hoses will cause them to become soft and eventually burst. And the smell of burning oil will become more noticeable in the cabin.

Other than because of that particular issue, the timing chains should last the lifetime of the engine. A 2012 Frontier shouldn’t need timing chains replaced, but I guess there’s always the exception. I hope the new parts actually fixes the noise you heard.
