The spark plug seals are "built" into the valve cover. they cannot be replaced. They valve cover gasket is a separate gasket. Which also needs to be replaced when you get the new valve cover.

This is a common problem which usually occurs at 70K miles.

The valve cover is also plastic. Not sure why it cost almost $200 each for some cheap azz plastic.

 

This is a three year old thread and this issue has been beat dead. Noone can find a replacement. Only way is to buy the whole valve cover from infiniti. Search and you will find alot of what was done.

 

OK, did not see the OLDness of the thread, I can get things made from rubber, but will have to check the resistance to heat and oil, if they can assure me of that being covered, them I'm in the oil seal business! Let the dealer keep their mega buck plastic.

 

There is no way you can install the new oil seals onto the old valve cover. Unless your willing to do some drilling. Even then, the old valve cover is probably warped.

Just buy 2 new valve covers.

 

replacement parts companies never make aftermarket valve covers for our cars yet? is the valve cover the same for all vq motors from all the different cars its in? is it interchangable with other cars with vqs?

 

I contacted several aftermarket companies to see if there were willing to manufacturer an all aluminum or metal valve cover with replaceable orings for the VQ series. Seeing that they would be able to sell the same valve cover for a lot of cars and they would be able to make easy money on it.

All I asked was they make something that cost no more than the OEM covers and that the O-rings used would be something universal and can be purchased at auto-zone or pepboys.

The only company that responded with interests was Weapon R.

 

so is the valve cover situation the same for all vqs in all the diff cars nissan puts it in?

 

Yep. Just google it.

I just ran a quick search for the 350z and the altima.

 

lol nm i jus did a refined search and that gasket kit doesnt show up for the g35. silly me

 

You can try it but you somehow have to get your old seals off. I dont think they just pop off theirs a thread on here where someone else tried that. Rtv silicone with a gasket like that. Its all boiled down to just buying their valve covers and doing the job yourself if not under warranty or letting them do it under warranty.

 

can anyone post a picture. cus honesly ive never seen wat it looks like so i cant really judge. i mean someone had to put the seals in the cover from the factory. or was it somehow molded into the cover from the press?

 

There are no silicone or rubber gasket for the plugs. Just a round piece of plastic molded into the valve cover. Over time, the plastic melts causing the oil leak.

In order to install some o-rings or gaskets, you have to dremal or cut out the plastic piece that is sticking out. Not sure how well this would work.



As you can see, its a pos plastic valve cover. Unlike the metal valve cover with replicable o-rings other cars have.

 

oh i see

 

Bought at a Oriely auto parts

 

Did it work?
