Been doing a lot of research on this issue and looking for some info from anyone that has used the various products out there... I first checked out the R&D factory $120 set up for some gaskets.. Then started doing some research and found that the 2002-03 Pathfinders and Qx4 run the same VQ35DE and the valve tube seal part number is 13276-AH100 and are 3 bucks a piece. Just looking to see if anyone else had run across this information and have used theses seals... Has anyone had any luck with the L-Fab re-man valve covers? Just want to do this one time so looking for my best options.....

I have some L-fabs on the way and will post the outcome. From the emails--they said these are longer lasting than oem but who knows the proof of that. For their $175 covers(including gaskets and Pcv) will see wasup and how long they last. Worth a shot besides the delayed replies and all. Actually got some off a member that was selling their z and had these so not like l fab responded still. They said there was a wait list for the rebuilt covers, I replied how long etc, no answer yet. Who knows.

Also very interested, need to do this fix asap. for those of you who do have the oil leak into the spark plug tube, does your car have a rough idle on occasion? Changed my spark plugs and my idle was perfect, now I have a feeling they are flooded again and having the same issue i was having with rough idle.

To me for the price and precision I hear you need to use the R&d kit it's not worth it IMO . Besides the fact you can mess it up and not get it just right for the money difference I would just a brand new oem valve cover and know it is fully replaced as it was intended to . That's just me and to people who had stated they just ordered it post your results I'm curious to see How it works out . Btw any one throwing a check engine light for this problem ?

Someone on here stated that the seals were from a 2000-2001 Maxima? but then i google it for the maxima. Its not even close match to the R&D seals!!!!

Does anybody have actual pic of the seals from dealership showing part#(pathfinder-QX4)or any? would help alot....

Would like to end this treads of mix info spark plug seals,oil wells seal, and etc....any input would help

I have been talking with a guy at the Nissan parts dept and this is what he sent me

So in theory they would share the same seal which he also looked up for me..
Nissan 13276-31U21. I have a set of valve covers and these seals on the way and I'm going to give it a try. My Z isn't a daily driver so I haven't been in a big hurry...

saywat?

^someones tried them before and they didnt work or they did it wrong, not sure. search for user "andrei" on here or g35 driver. i forget which forum. im assuming ur gonna try the seal mod process like l fab did but with these maxima seals?

OP those part numbers u gave is for some sealt for the oil filler on the valve cover (google it)

i have the l-fab cover. been a year so far so good. i dont drive much tho. hard to get in touch with both vendors Rnd being the worst. i wouldnt waste my time with them. L-fab is a little better with response but still lagging.

How about using the 04-08 Maxima's covers!!! The bolt pattern looks identical and they are about 33$ each.

The seals still look way too different then R&D seals...this is the part# from earlier today...We trying to figure out the valve cover spark plug seals aka oil wells seal, oil filler seals, and etc....

Anyways one side looks about right, but other side is flat! R&D has a taper lip on that flat side.

They look exactly the same, I'm looking at a brand new never used OEM 350Z valve covers that i bought from the dealer about a year ago and can see no difference .

The oil fill neck on the maxima valve cover isn't raised up like on the Z valve cover and there are a couple of Hose fittings that are in different locations. I did alot of looking at that as well. The front on the maxima is different, rear might work but I was waiting on a set of used Z covers I have coming to see if I could get any identification numbers to use as a cross referance tool. All of he bolt patterns are pretty much the same just slight differences for application front wheel and rear wheel drive.

saywat?

i wonder if the max covers dont fit u could atleast dissect the seals out of them and use the R&d method and put them on the g35 covers

jkeile3

That is pretty much what I'm going to do when I get around to it... Pretty sure these will fit as well.. Check the link here....

I've recieved my L-fab covers. Seems to be OK and working well so far. Getting in touch w l fab is a pain but finally said he was processing the core refund. They say these last a lot longer than OEM and I shall see was up down the road. Not sure what else to tell the members. sorry. Was a roughly idle etc and throwing code but now seems a little better. Will keep updated.

Since I had my intake off to chase down the slight oil odor issue I was having - and I couldn't wait for any answer from our resident seal sleuths on exactly what part # those seals are (and I wasn't about to pay exorbitant prices for them), I used Permatex non-hardening gasket maker.

If it doesn't work, I don't see any harm done; just a bit of cleaning up. Here's the issue as I see it:

The design is clearly stupid. Nissan engineers decided that it was smart to attempt to seal off the spark plug tubes from the valve covers using these rubber donuts, when what they SHOULD have done is seal off both the coilpacks and spark plug tubes from the valve cover by using the COILPACKS as the lid for the metal tubes. Derp on them.

My driver's side plug banks were completely dry. The passenger side #3 and #5 were wet, however. Without taking off the valve covers, what I did was clean out the recess around the plug tubes and the valve cover seals (drying it out with a paper towel wetted with carb cleaner), and used my finger to force the Permatex into that surrounding recess, filling it and then smoothing the material around the tube and adhering it to the valve cover itself. I don't see why this won't work, but I suppose I'll eventually find out.
