I bought a PCV Valve for my girls 2003 Maxima and I tried changing today. Couldn't change it though because I was sort of confused. I'm not even sure if I got the right PCV Valve. It is Black on top and a light grey at the botom. It has 45B756 etched in the black portion

I located the PCV valve in her engine. I then took off the clamp and hose. But the valve didn't look like it wanted to come out. Looked like it might need a wrench or something to screw it out. Is this correct or do I just pull it out because it didn't budge for me. Can you guys please help with this?

Need wrench, should be 21mm.

Jibberish18

Thanks. I don't have much room in their. Any tricks to getting it in there or should I just make due with what I have?

Also, does this mean that I got a wrong PCV Valve?

I have not bothered with mine yet since I need to remove my FTSB first, but I can imagine a universal joint might be helpful.

Oops, it might be a 23mm...I don't know for sure sorry.

it's 23mm...I know cuz I got pwnt tryin to use my 19,21,22...then had to shell out $5 to buy a 23

it's recommended to get a deep socket too...cuz a regular socket might not fit on top of that valve..

How many miles on the car when you changed it?

Jibberish18

That's for sure. I didn't have any deep sockets and I'm not sure if I had a 23mm socket wrench. But none of them wanted to go one. At least now I know how to take it off.

But the questions still stands. Is it the correct PCV Valve? Sorry to be bothersome.

could you possibly take a picture? then i'll be able to tell...if theres threads on it, it should be the same one?

n3985

Your replacement would look like that ^, the factory one is all black though.

thats how mine looked like! I just changed it becuz I got bored...I mean, my old one was still rattling inside (meaning its still good)....but I said whatever, the part only costs $6

Too bad I got pwnt only to find out I had to run to the store...and buy a $5 just to do this job...what a hassle

Jibberish18

God bless it! The parts guy gave me the wrong one! First he tells me that the PCV valve is $249 LOL and then gives me the wrong one which he special ordered.

Actually her original one is white on top too.

I think I saw the original part # somewhere on the site. I'll start looking for it. Thanks for the help guys!

I payed $15!

Thank Zero Deuce SE, he provided me all the pics and links.

Jibberish18

hey thanks for that parts #. I looked into the website and I found a part # 11810-8J101. The link you posted shows a 11810-00014. Which part # should I give the dealer tomorrow?

n3985

iTrader: (36)

When I called, the dealer said the 00014 is invalid, so maybe Courtesy Nissan assigned their own internal code

steven88

iTrader: (28)

okay maybe I was exaggerating about the $6...its more like $8 or $9....the $15 you paid is the retail price nissan sells it at....I get my parts through dave B...and he hooks up .org members and sells the parts at retail price minus 25%...

Does anyone have information for the PCV for a 5.0 gen? I've got the new part and it has no threads..do I just pop the old one out? What should I use so it doesn't crack?

Jibberish18

What year? I'm not sure if the PCV Valve for a 2000-2001 is different than the one for a 2002-2003.

djfrestyl

iTrader: (89)

It is different. The 2000-2001 does not have threads.

Dumb Question

Whats the benifits of changing the PCV valve, i have an 01 is 84k on it. Should i change it too.

Maxima@usa.com

when I did a tune up on my car, I also got the PCV Valve but forgot to install it and after reading this thread I remember.

Can someone tell me how important it is to change the PCV Valve and what effects does it have on the car.
Please educate us on this.

Still nothing on the benefits of changing it or not?

I rarely say this, but this question can be very easily answered if you simply search on Google, here is the very first result.

Hey guys. Part ## 11810-8J101 is no more. The new part # for the threaded PCV Valve for 2002-2003 engines is # 11810-8J102.

I haven't changed it out yet because of some complications as of lately, but will do it as soon as possible and post back on any noticeable changes in drivabilit (probably not but ya never know).

Oh and it was the same price of about $15.

spiromax

My stock one isn't black or white on top. It's yellow (not stained, actually yellow)...

As far as I know, the only place to get a replacement pcv valve for a 2002/2003 Maxima is from Nissan, because all of the auto parts store chains around here keep telling me "it's a dealer-only part."

So... you guys have made references to black tops and white tops, and I have a yellow top. Jibberish says that there have been two factory part numbers for the 02/03 valve. Were there actually 3, or is something else going on?

Jibberish18

Many thanks Zero Deuce SE.

As far as I can tell there were only 2. Part# 11810-8J101 was the old part # and if given to a dealership, will be referenced forward to part number 11810-8J102.

Part#11810-00014 is invalid I guess. I saw it on Courtesy Nissan's website. But n3985 said he called and was told it's invalid. So in the end, for a 2002-03 Maxima, only part #11810-8J102 matters if you need a PCV valve.

Zero Deuce SE

You're most welcome. Always glad to help.

Jibberish18

Well I changed the PCV Valve today. Had to buy a 23mm Deep Socket. Came out quite easily actually. Took the O-Ring gasket off the old PCV Valve and put it on the new one. Both old and new PCV valve looked identical. The old one still had about a good 10K miles left for it to need changing. With the price I paid for this dealer only item, I would've just left it on there. But it was gunked up a bit.

mdsmithers

Really? how can tell how many miles it has left?

Jibberish18

Heh. I'm guestimating it. After about 31 K miles the PCV stills sounded fine. So I'm guessing I could've kept it in their for at least another 10k miles which I probably will on the next one. I could've spent $16 on other maintenance such as adding more R-134a refrigerant.

Zero Deuce SE

I changed the PCV valve in my 92 Max at 100,000 miles and it was still fairly loose when I shook it.

I was at my dealer on friday and he couldn't find the part number of the PCV Valve, so i just want to ask what is the exact name of the valve? After i made a research by my self, found this:
Is it Valve Assy-Control with part number 11810-31U00(11810P) or Insulator-PCV Vlave 11812-41B00(11810C)? Probably it's the first one, so what does Valve assy-control stand for?
BTW, me engine has a little consumption of oil, so that's why i decided to replace the PCV valve....
Thanks

Here's a pic

naxray

It's the Valve Assy-Control with part number 11810-31U00. Just got one from Dave B ($8.18) and that's what's listed on the invoice.

Oh, thanks a lot! I thought it was the second part - Insulator PCV Valve 11812-41B00...

navyflyer72
