VQ35DE Valve Cover and Gasket Replacement How-to
#43
sorry old thread but what is the main difference between the 5th gen and 6th gen valve covers? Does the 6th gen valve covers completely eliminate the issue?
I have a g35 and stupid infiniti decided to bring this issue to us too. So I was thinking the maxima guys probably have the same problem and found a good fix.

Call Dave B at 888-254-6060 and check with him, even though he's at a Nissan Dealer he could still offer advice. Or perhaps pass you to an Infiniti dealer for detailed advice.
Also eliminate what issue? The issue that requires new valve covers is oil leaking into your spark plug tubes. Pop on the 2004 Maxima valve cover and no more oil in the spark plug tube(s).

Bump because I noticed this about 2 months ago but never had a chance to do anything:
Pretty sure that is oil buildup under my front valve cover. Seems that most of you are having issues with the rear valve cover. Anyway, new valve covers will be ordered shortly from Dave B. I need to clean that engine bay up at some point I guess, lol.

I know it's an old threat but, I got a quick and maybe stupid question but I am not a mechanic. I found some oil on the spark plug Cyl 6 (front right) and I want to change the valve cover gasket and the spark plug gasket; now the question is: Do I need to change the valve cover itself? If I am getting new seals, why would I need a new plastic cover? please be nice
Mine is a 2000 SE.

You need only to change the valve cover gasket, screw grommets, and spark plug gasket. You dont need to change the valve cover, since its made out of metal. Also, the spark plug gaskets are PITA to remove because they are attached to valve cover pretty tight.

Aren't the covers made out of plastic? mine are in a 2003 GLE. sorry if this is a newb mistake.
#52
You might be thinking about a 3.0? The 3.5 cover is plastic and one piece, even a new pcv valve comes with it.

Question, is an oil drain needed to replace the valve covers? All info I find from searching simply says remove the upper intake manifold collector to access both valve covers. Nothing about if an oil drain is required.
Thanks!
Thanks!

I notice a buring oil smell after driving around while at a stop after replacing the valve covers.
I only applied a light amount of http://bit.ly/fTYtxs all the way around the rear valve cover but had a bit of trouble getting things to line up. Hopefully a remove and reinstall with new gasket sealer solves the burning oil smell.

Ok...Im contemplating doing this. One of my mechanics quoted me $210 to do this....this is getting expensive! Regardless, based on this write up and Greg's IM removal...it looks like an easy enough job.
My engine is burning oil and although i don't plan on getting rid of it, I'm sick of it at the same time . I haven't had my guys evaluate it yet, which would be the smart thing to do, but I like to troubleshoot and diag things myself. Do I think this will solve the problem, NO. Do I think it may slow the oil burn down, POSSIBLY. It's a risk I'm willing to take.
How many people have actually done a Rear Valve Cover and Gasket replacement on their Max, with an 04 RVC/Gasket? What kind of issues did any of you run into, if any? And did it help the oil burning issue at all?

Preciate the feedback and quick response Slim. Yea, it looks simple. I just want to do it right ya dig. And like I said, I don't expect it to "solve" my oil burning problem, but hopefully, it will slow it down a little. That's why, I'm not giving up 2 bills!

no problem...i had to do my moms I35 spark plugs and found out the hard way i had to remove the UIM...i was pissed at first, but when i got into it and realized it wasnt that bad, i wasnt TOO upset. if you're a novice..i say give yourself 3hrs
#62
This is not something you want to get from the junkyard. The spark plug tube seals are made into the valve covers from the A34. Why gamble? It's like 40 bucks for each one. Cheap.
#64
Why do people thinkreplacing a valve cover will help with the burning oil issue?
Oil burns because it goes pass the pistion rings into the combustion chamber.
There is hardly anything besides an engine rebuild that will fix that

I'll be doing mine next week. I called dave and ordered the parts already. Anyone know of a writeup or "tips" for a 2000 3.0? I've searched the 5th gen and 4th gen forums but still not finding a writeup for the 3.0. The 3.5 writeup is great but the 3.0 gets labeled as "harder" with no write-ups or tips, just complaints. I'm mainly curious of how to remove everything and what needs to be removed, as well as what needs to remain attached before I start via "trial and error". I only an afternoon for this to be done so homework is crucial!

OT:
Ok, I'll bite. Here's the write up for 90% of the time and effort it will require to change your valve cover gaskets. It's in the 4th gen stickies. If you have any questions after that, the task should be left to a trusted mechanic. Good luck.

^just an FYI..you have basically four 'hidden' bolts behind the UIM that you have to feel for. they are 12mm bolts, then you have the two bolts almost right below the TB, 10mm i believe...but the hardest part are those four hidden bolts, once you get those, its pretty much cake...even putting those 12mm bolts back on and tightening them is not even as hard as taking them off

I'm going to order all parts, so I can tackle both VC's. Its the easiest isn't it...any tips there mane?
#76
I feel you...but...I think everyone here is aware of the fact that this may not "fix" the problem that many of us are all having. If this was the definite answer to all oil burning questions....then it wouldn't be a constant, reoccurring topic of discussion on the org.

Hey guys, i have an 02 that has a slight oil leak at the valve cover gasket by the dipstick, and i can smell it while driving with the windows down. Im assuming gasket replacement is what i need to do? should i do front and back? Exactly what parts do i need to order? This is my daily driver so I just want to be prepared so i can get her back on the road asap, thanks for any input
#78

#80
