the spark plug tube o rings on the 350z are not replaceable. I don't know what that kit is for.

How can you say they are not replaceable if R&D used "unknown" grommets to replace the ones on the valve covers? Maybe nissan calls them non replaceable but its not like they are physically bonded to the cover...

From what I can see (which is why I posted a pic) that particular set from that company comes with a grommet set. So if R&Ds instructions called for drilling a hole in the baffle to fit a larger grommet, I will probably do more searching and pick up that B/A kit and see if the grommets fit. All I know is there is no way in F#@[email protected] hell I am paying 500 bucks because a 2 dollar part failed....

Well I fail at life. Lol so I'm changing my vcg today, and I saw how different the stock spark plug gaskets are. They differ by about 1 mm from the one I got for the "vq35de". So I put the old seal back and sealedit with vrt gray. Looks awesome but lets see if it will hold, that was leaking anyway so I don't think it couldbe wworse. I will be getting a used valve cover and swap it out if this leaks. I also saw my valve civer breather tube was broken, so I'm going to replace mine, maybe AutoZone has hoses.

don't know why you went through all that trouble when clearly they're not replaceable.

It wasn't that much trouble TougeZ, I needed to change the cover gaskets anyhow, so it only took maybe 20 more minutes to open the hole and remove/ inspect the leaking seal. The seal I bought matched 80% but it was about 1 mm short on outside lip diameter so it did not fit exactly. So I took the old seal and sealed it in the valv cover with rvt. The worse that could happen is the seal leaks, which just means I have to do the work again, which to me isn't that big of a deal. I made a video of my work and I will be making a thread tomorrow for it. I am sure it will help someone. Also now that I took the measurements of my seal I can go ahead and find an exact one, becauseif R&D can sell them from nissan, I can find em.

Just an update. I do not have a trace of oil in my spark plug tubes since I did the permatex fix; it's been about 5k miles.

If you don't have leaking at the valve cover itself, this is the way to go IMO.

More people should do the permatex way if you just have a spark plug tube leak. It's much easier than valve covers. If done right, it's actually a permanent fix.

Update, I took a look at the valve cover today. NO OIL in the tube with the RVT sealer (Gray) been driving around 500 miles for the last couple weeks on it

Good to hear go7roo7. The only hard part applying the rtv is the little space you have to work with.

It's not really that bad, after I opened up the hole using the hole saw, I generously applied the rtv to the inner \/ part of the seal and the inside of the seal seat on the valve cover. I pressed it in place then added some more rtv on the outside. Then I left it out to air dry for 24 hours. If properly cleaned and degreased, there is no reason for it to leak. Plus it beats swapping covers.

You guys use loctite on valve covers bolts? Blue or red, if so?

Thanks

That's a negative Ghost Rider.
FSM doest call for it, and personally I would not risk stripping the bolts ( or damaging the threads on the head) to apply loctite. BUT! if I had to use it, I would use BLUE, never Red.

No prob . I have had people tell me my videos are too long, but honestly I would rather explain things in detail, instead of having people complain that I did not mention it, or that I was not clear.

ok so I did my valve cover gaskets today and my sparkplugs because I didn't know when the last time they where changed. While doing this I did pull off both cam actuators. Car ran perfect before doing this
Im now pulling codes
p0300 Random Multiple Cylinder Misfire
P0011 cam position actuator a-bunk 1 timing over-adv
P0021 cam position actuator a-bunk 2 timing over-adv

Any Thoughts?

Did you buy pregapped spark plugs? Did you check the gap before installation? Did you use a torque wrench?

Ironic. I just did my other valve cover gakset bank 2. I used some tinyRtv under and over on the actual gasket bc I was getting a leak. Mine are L-FB rebuilt covers w brand new gaskets. Didnt read entire thread but I would def add a little rvt or gasket stuff to be safe as you're in there unless you wanna dig back into it like I did.
