Just found a leak in my #6 cyl. I am contemplating if I should do the R&D cutout mod on just that cyl and use a combo of RVT + a gasket from the 03 maxima which seems to be the same one ( so say several forum threads), or take both valve covers off and do the mod to both banks....


This is what I found...








I was thinking of getting this gasket set (since it seems to come with the grommets)



Or buying one of these individual grommets

Who has done this before? I got the R&D seals but I cant drill out the covers. Without anything in the middle for the bit to grab on to the saw just jumps all over the place.

The trick is to go slow, I would run the holesaw by hand to get the teeth to bite and create a small channel. That and if you get a holesaw with more teeth ( like one for metal as opposed to wood) it will be easier to get a nice clean hole, also follow it up with some sandpaper. I contacted R&D but they haven't responded in weeks, so I will be trying the QX4 spark plug seals, which are the ones pictured in my previous post.

If you use a drill assist with the hole saw, you can put a piece of wood under the valve cover and use the hole made by the bit to stabilize the hole saw. Use C- clamps to hold both pieces together.

I have a set of valve covers not on my car with blown spark plug tube seals, if you guys want me to experiment on them send me 1 spark plug tube seal of whatever make/model, and I'll cut the inside of the valve covers open to see if it fits. PM me if someone wants me to do this, then maybe no one will have to pay L FAB ridiculous prices for these things anymore.

Is that your video? A little long so I didn't watch the whole video but it's like you're there during the install -- very nice.

Thanks to you guys for the info about replacing or trying to replace the spark plug tube seals. I've just found out after replacing my spark plugs that those seals had busted on a couple of tubes. After doing a Google & Bing search I am finding that I've got to replace the valve covers to get those seals. WTF! Sorry, I've never heard of such a thing till now. Seeing that this engine is in a couple of other models can you not use those other VCs from those other models? Z covers 180 to 280 each, Maxima covers 40 to 90 each. What's the difference other than price? Thanks as always for your input.

Someone else has tried maxima covers. I think he ran into an addition problem, maybe plenum or something, and gave up.

I'll see if I can find the thread

If anybody needs the seals from the covers I have them for a DE. The only seal leaking was the #6. Seals are still on the cover, just cover shipping.

I know this thread is dead as hell but anyone with input in soing the seal replacements and how its held up

Is it really causing any problems? Mine has been leaking since the first spark plug change and I've never had any problems. I now have 285,000 miles on my car.

The 350z has the ''baffle-type'' valve covers, so just replacing the tube seals themselves isn't possible unless you perform an unorthodox method(which is using a 1 7/8in. hole saw to cut a circular hole in the plastic baffle in order to pop the old seal out so you can then put the new seal in). Unfortunately, the only other way(besides using Permatex) is to replace the valve cover as a whole, which will contain the new seals.

I resealed my old seals both on the inside and did a weld bead of RTV on the outside of the seal ( waited 24 hours to dry). 5 years in and still no leaks. I have not found RTV chucks in my oil or oilpan so the outer bead must have held up well.

I am still actively trying to find the part number to these seals.
