My fix is to follow the R&D instructions to remove the old seals, and if they are not cracked, reseal them back in (after cleaning valve cover and seals with brake cleaner) with Gray or black RTV.

My video on said fix.

 

I did this last weekend using the R&D kit over here, sure it took quite a long time to do it but I believe this method should far outlast the OEM replacement covers.
The above video is invaluable, as to is a print out of the manual

(and the correct tools of course)

 

After watching this video, it really reminded me of why i did my wire tuck. Well at least there are 2 decent solutions for our valve cover issues. Personally i am gonna go with the maxima covers once i am ready. I really want the lower filler neck for a cleaner look. Plus i plan on doing a little massaging on the new covers to give them a cleaner look before paint. This is just another step in my engine tuck.

 

I can't see the point if they are going to go after 30-40k
(bar what you said about the filler)

I just re-visited your engine tuck - man that's amazing, I've not a clue how you do it but that makes things look soo much easier to work with.

 

Actually the newer 04+ maxima covers are not prone to leak. The older maxima owners on the maxima forums are using these with no problems. Either way

 

Oh and thanks, 50 hours during xmas vacation; patience and vision help alot. Plus a huge amount of research that came more from the G35 guys. Still have alot more plans to clean it up alot more. One of my idea will be huge and should be a first. But will save that for the future and to not rob more time from this thread

 

One last question, do I have to replace my new spark plugs that I put in because it's not going to be two weeks until I get to change my valve cover gaskets.

 

shouldn't need to, just clean the oil out. Take a paper towel and wrap it around your finger and use the hole you make in the towel to slip over the plug to soak out the oil. Will take several towels to do it.

 

Or spray carb cleaner onto a microfibre cloth and wipe off the oil.
Just be gentle with it

 

THIS! this job sucks for 1 reason, THE S^#$%^# F^#$ OEM WIRING!

 

Too true
