you mean oil in the spark plug tube. if so, the tube seal is worn/damage. the seal is installed on the valve cover.

When I pulled the spark plug out, the oil was dripping off the plug. So I assume the tube had oil in it. Thanks for the info bennyb. I will get the seals replaced asap.

1. just to let you know the seal is not replaceable. you will have to buy anew valve cover for 3rd gen Altima anyways. i have research this cuz one of the seal on my 02 altima is a bit soft/worn but not leaking yet. i think a new one is about $140. online.

i was thinking when that happen, since i have left over Permatex Ultragrey gasket maker, will it work if i apply it around the tube after you re-install the valve cover - may be try that at least as a temporary fix. check eBay also or a salvage yard.

I'm having the same problem on 1 & 4. Valve cover replacement is the solution? Are you saying there is no gasket that can be replaced? How much damage could I have caused driving it?

I'm looking at item #15 stated to be "Valve cover gasket" which is about $8.02 on a site that i'm posting at the bottom. Why would i need to purchase the Valve cover if the gasket comes separate? Besides its around $105 for the valve cover and it doesn't mention anything about gaskets and seals that comes assembled. Bennyb, are you sure about this? I've also noticed that the spark plugs come with seals as well, but not sure if that is the reason for the leak or if the spark plug seals come bundled with the valve cover gasket when you purchase the valve cover. I have posted an image at the bottom which shows the valve cover, spark plug seals, and valve cover gasket.

Unless things have changed, what benny wrote is correct. You may find something aftermarket, but I know a couple of years ago I could not find a gasket from any parts house and you could not get just the gasket from Nissan, they only had the entire assembly available.

Not sure why this is done that way.

The diagnosis is correct though, the spark plug tube gasket is leaking (look at the top of the tube where the valve cover contacts it). The permatex solution may work. A guy worked on my daughter's Altima, put it back together and smeared a small amount of some sort of sealant, almost like a grease, that stayed in place and kept oil from finding it's way into the tube.

Thank you every one. After reading this I was able to change valve cover gasket and spark plug seal on my 2003 Altima.

Check out this video to get a clear idea how to do this:

Do not put RTV in the valve cover groove or on the top of the cylinder head. The only place you should use RTV is where the gasket makes a sharp bend on the side near the timing cover. You only need a small dab.

Thanks "dr_UMMER." I understand the valve cover replacement. Even though I had no issue I replaced it anyway during my HG replacement cuz the Kit I purchased came with valve cover gasket.

However, can you tell us how you replace the spark plug tube seal? As the video presenter himself made it clear that if the seal cannot be repaired you will need to replace with a new valve cover. Our community would be wholly indebted to you how you replace the spark plug tube seal. Thanks.

There is a supplier out of California that now sells replacement spark plug tube gaskets for the 3.5 valve covers. You use a 2 inch hole saw to drill out the old seals and use RTV to secure the new seals. I recently did that to my G35. You have to buy 6 seals but I only used 3 because the other valve cover seals were fine. So I have 3 left over if you want them.
