how hard is it to install PCV vavle on a 97 Max? does it required Nissian PCV or anything generic PCV valve? does the PCV valve have to be all the way in on the mainfold?

 

well you want to be sure that it does not cause vaucum leak. Just take off the hose to the pvc valve and screw it out and screw the new one in good.

 

what does the pcv do? also what will happen if you do have a leak

 

If you have a vacuum leak it will cause surging and things of that nature.

sweet username...

 

The guy is probably the biggest d'ouche on the .org.

 

Probably? Unless there is a "Biggest Douche on the Org" username I think he's got it.

 

pretty easy

though it took awhile for me to get the hose off the PCV valve itself because of how short it is, ended up just using vice gribs and ripping it off after getting frustrated...

didnt hurt it though

 

If you cant afford to spend the $3 at a local auto store, spray TB cleaner into a cup, and let your PCV valve sit in it. The build up will get broken down and your PCV valve will be almost like new.

Shake it before you do this, if your pcv valve is rather clogged you'll hear no rattle. After soaking it in TB Cleaner for about 5-10 mins, shake it after, you should hear the rattle.

 

Positive Crankase Ventilation. when a piston is going down it creates positive pressure underneath it, allthough another piston is rising and creating negative pressure at the same time, the pressures can't equal out fast enough so there is going to be some positive pressure at some point, this must be vented or it will blow seals and gaskets, because of blow-by and the like it must be vented to the intake for emissions purposes, since it's going to the intake it has to have a one-way valve so as to not cause a leak. If that one-way valve (the pcv valve) clogs up it can blow your rear main seal or other things. imho I would buy the nissan pcv as opposed to saving a $1.

 

excellent explanation.

i still cant find it.....of course i wasnt looking very hard

 

on the intake manifold to the right of the left of the coil pack on cyclinder 5. Right next to all the TB cables.

 

i installed the PCV valve already.....but the part that should be connected to the mainfold is not 100% in.....it has about 70% left to be pushed in......it was hard for me to do so......would this creat any problem? however.......my car do shut right off when i turn the car on early in the moring.......you think this have to do with the PCV vavle?

 

this might be alot but can someone take a pic of the pcv valve and post it here please.
i remeber this time i was gonna get mine changed and looked it up in the HOW-TOs and the FAQS and i found it with pics and everything, now i am looking nad i just cant seem to find it again. i think it was in the how to section....

 

it's litterally stuck into the crank case at the top just to the side of the TB
and it might be hard to pull out. just work at it for a minute and eventually it will come out. you will have to take off the hose thats attached to it to pull it out, and if you have a strut bar and are too lazy to take that off like me it will be kind of a pain to get the PCV valve out.
