Hi all , I have a friend who has a 99 Nissan Altima. I'm doing some work on her car, but I cannot seem to locate the pcv valve. Does anybody know where it's located. Thanks for any help!

Thanks I appreciate it. Since I'm not too familiar with this vehicle I might be asking other questions!

Re: 99 Altima pcv valve need help Sign In

Just going by what Tom said.....look at the intake manifold area...thats the manifold in the back part of the engine..nearest the firewall..
The heat shield usually covers the exhaust manifold area...and exhaust pipes area....

This a pic from a year earlier I think...look like yours???

You may have to look under the intake area for it...sometimes they are in a hose itself...I'm not sure at all on NIssan's

Ok: forget the second pic as this isn't using that. PCV up top if that's the one is in-line and would snugly fit into grommets like shown last above into the intake manifold. Look for hoses that could hold that thing - may or may not use clamps - dunno.

Dist rotor. Check for any possible locking screw. Guess I'm full of "dunnos" today - it might have some hidden fastener and it's worth not breaking it. Gentle taps with like the plastic end of a screwdriver might help. If/when it comes off you might just put a smear of WD-40 like on the shaft so another time it won't fight so hard - some do. I'm bad about these things - if they look real good with no sypmtoms they don't get replaced.

Keep at it and looking - you'll get it,

The rotor does have a hold down screw securing it..

Re: 99 Altima pcv valve need help Sign In

Thanks for all the help guys, I did get the rotor it was just stuck, I did however look at a repair manual at Advance which said the pcv was easier to get at from underneath near the drivebelt side, but believe it or not I still don't see it, but I'll keep looking. She is actually a friend of my wife.

One more question, When you start the vehicle it cuts off almost immediately. I have replaced the spark plugs, distributor cap, and rotor button, but it still cuts out. Any thoughts as to what this might be ?Thanks

Re: 99 Altima pcv valve need help Sign In

Did this just happen with the work you have been doing? The hoses for PCV (any vacuum hoses too) and the snorkling of the air cleaner rubber parts and the electrical items that you may have removed must be back on and snug.

Can you keep it going by playing with the gas or is this quick stall out emminent?

Re: 99 Altima pcv valve need help Sign In

It happened before I did any work, and yes it will stay running when you give it the gas, and let off the pedal- any ideas what this could be? Thanks

Re: 99 Altima pcv valve need help Sign In

? - Is that to say it will stay idling with some fiddling with the gas and you can let go or it always dies out?

For the moment that would be consistant with a vacuum leak but lot's of things are possible. Try to explain just how and when that happens........ only when cold or whatever noticed would help,

Re: 99 Altima pcv valve need help Sign In

While starting the car, you have to pump the gas a few times and hold the pedal down to get it to start no matter if its cold or not, and even then it will stall, but after a couple of times doing this it will catch and idle. I don't know when the fuel filter was changed last, could that be it? Thanks

Re: 99 Altima pcv valve need help Sign In

If it's been a while a new fuel filter is a good idea but I don't think that's the up-front problem.

Pumping gas pedal doesn't really pump fuel like a carbed car does - this is fuel injected. It really is just confusing the compter for initial start up - hey - that's OK - it's our turn to confuse a computer!

I would get a full code reading and put a fuel pressure test on the list too. It may be borderline or low while cranking and adequate when engine is actually running as alternator is putting out a bit more voltage for it to work with. Hard to say and will need some testing.

Codes may be in wait even it the "check engine" light doesn't stay on and that can only help. Major parts stores are doing those gratis in most places. Check that anyway.

Does it run well once started and will it restart normally if you have just shut it off - like in a few seconds, minutes etc.,

Re: 99 Altima pcv valve need help Sign In

I do have a live data scanner that said p0325 knock sensor problem. It does run once you get it started, but getting it started is a big problem, if you shut it off it will do the same thing and take messing with the gas pedal once again, in other words it won't start right back up. Thanks

Re: 99 Altima pcv valve need help Sign In

check your spark plug wires. It is most likely loose or the wires are mixed up in the wrong place.
