Valve Covers
I think I read somewhere that it was recommended to use 2004 valve covers on the 5.5 Maxima. I'm going to be replacing the valve cover gaskets and wonder if it's worth it to replace the covers as well.

You can replace the gasket between the cover and the head, but not the seals around the spark plug tubes. These are consistently places oil leak, particularly cylinder 5 for some reason. The rear 6th gen cover is too cheap not to buy it and go ahead with replacing it. Go ahead and replace spark plugs as well. The rear cover also comes with a new PCV, so don't worry about buying seperate. No need to replace front cover unless known leaks exist.

I just took a second look and it looks like you're right. The owners manual and the FSM call for NGK platinum tips. My bad. I've never had a problem with the iridium's though so I would still recommend them.

Wow, had no idea the price was that different! I guess I'm asking if there is any difference between the different valve covers. $140 difference in price suggests something, whether its materials or whatever. I suppose if they didnt work you would have mentioned it lol

I'm not sure what the exact differences are. When I get around to swapping mine (I ordered them yesterday) I'll try to post some pictures.

Yes.
What is fsm? What about owners manual? Now when I think about it, the Maxima is inline 6 RWD. If cylinder one is on the very front then cylinder six is by the firewall.

FSM=Factory Service Manual
A lot of times the location of plugs can be confusing to some because of the position of the engine in relation to the car. From what I understand, the front of the engine is considered to be where the belts are located, so, plug No. 6 is located at the front-right of the vehicle (page 9-8 of the owner's manual), which is the same to say at the rear-right of the engine (page EM-88 of the FSM).

I wouldn't use your recommendation on window cleaner, let alone spark plugs. So GTFO.

The fact no one reponded to your initial post in this thread should had been confirmation it was at face value, helpful. Guess it was too much to expect that you would not subsequently require some affirmation of such appropriate behavior.

Thank you for clarifying my comment, rebelhell; I was basing the locations based on a person standing outside the car, looking at the engine compartment.
