Valve cover removal

Afternoon all,

I need to replace the leaking valve cover gaskets on my daughters 92' SE Pathfinder. The passenger side cover is very easy I can see. Can anyone tell me what all is involved in uncovering the drivers side valve cover as it is buried under the intake system? Do I need to remove the induction system/manifold and just fold it back to get to the valve cover or can I just undo the EGR pipe and other associated accessories and slide the cover out from under the manifold?

Thanks.

Sid

I recently purchased a 1990 SE, I just did my valve cover gaskets. It was a pain. Taking that upper intake manifold off is what takes all your time (plus cleaning out the sludge in my valve covers). And getting the hoses on the rear of it (up against the firewall) off are going to hurt (literally). The haynes manual wasn't much help for me. I would recommend using tape and marking each hose and wire you disconnect, maybe even a bright colored electrical tape so you don't miss any. The wire connectors they use aren't the best. You have to pry off the metal clip and then they slide apart. Don't forget to buy the gasket for the upper intake manifold too. Good luck. Maybe the chilton manual is better.

I have a 97, I'm not sure how similar they are, but I had to remove the intake to replace my gaskets also. You can do it, just be ready to spend some time on it. The hoses in the back were a serious pain, so it's easier if you have someone hold the intake up while you are dealing with those hoses. You might also have to replace the intake gasket too, so pick up one of those up before you get started. You should be able to get it done in an afternoon.

The first time taking the upper intake manifold off was definitely a learning experience for me. But now I'm sure I could do it faster. Took me a full day plus a few hours to get it all done. But that includes running around for parts and an hour + for cleaning the valve covers. The 97 is a little different, but very similar. The distributor has to come off too. I've never really worked on a car with pistons, I'm into the rx-7 rotary engines, took me a while to learn that the distributor actually pulls off. Just makes sure you mark where it is or your timing will be off.
