It's all over the archives. A little searching will tell you what the hell it is and why you need it, in addition to where you can buy the kit. I'll throw you a bone though -

It's too specialized a product to be available at autozone or ebay. You can purchase the kit from www.genuinesaab.com or from www.eeuroparts.com. Genuinesaab has a step by step instruction manual in the service bulletins section of their website. They call it the 'Crank Vent Kit', by the way.

I shopped this kit a few weeks ago, and eeuroparts.com had fantastic prices. They're in CT and orders over $50 were shipped free via FedEx. There are other parts you can get with it to make it more complete, but the $55 kit is good for a start.

It is definitely a DIY, pretty easy to do (will probably take an hour or two depending on your skill level).

The biggest changes in the kit are the introduction of check valves and a new connection to the oil dip stick tube.

Look here for some more explanation with pics:

Before you tackle something like that though, figure out why your computer is capitalizing every word.

That has to be one of the most annoying ways to have to read a post. :roll:

It is a doable DIY. Just did it a couple of weeks ago upgrading from PCV#4.

Check also if you need additional hose, I believe there is two other hoses that would be better to change (not included in the PCV#6 kit). If those hoses are soft ( does not go back to it's original shape after squeezing it).

Best to do it if you have a ramp, as you need to access the PCV box at the rear of the engine from the bottom. Ok I guess if you have jack stand.

It takes me slightly more than two hours to remove and install.

I dont mean to pee on anyones ideas here but IMO the update kit is very bad. It causes a much higher oil consumption over a correctly functioning factory set up. Can use as much as an extra lt per 4000km over factory set up. I have tested this many times and as such what I base my opinions on. I have removed some of the kits and also seen an improvment in consumption.

Sorry to say but once again (remember the 5 previous ones didnt work either) unfortunately Saab have got it wrong.

Having said that if you system is currently stuffed (broken hoses, blocked nipple, valve or blocked cam cover ports) you may see an improvement. Just IMO the factory system is best but must be functioning correctly.

Would you care to explain your position a little more?

You are the first (and only) person I have ever heard suggest this ... and I work pretty closely with a Saab Master Tech who installs this quite often.

I need to be clear when I tell him, all of the other Saab specialists, and Saab themselves (wow ... what a waste of money there) that they have it wrong and shouldn't be doing this.

SAVE THE DEBATES FOR LATER I GOT A PROBLEM I NEED TO SQAURE AWAY. CALL ME ALL CAPS. NOW THIS SITE HAS A GOOD PRICE $50 BUT IT SAYS THIS MAY OR MAY NOT BE EVERYTHING I NEED SO WHAT ELS IS MISSING?

TO BE HONEST THEY JUST LOOK LIKE THICKER HOSES SO IS THE LARGER FLOW OF OIL GOING TO REMEDY A LEAK BEHIND MY ENGINE BLOCK? SO I'LL DO A COMBINATION OF , OIL SENSOR, OIL SWITCH, UPDATE PCV #6 AND CROSS MY FINGERS.

Hey CAPPY!
We're happy to help...just ask, no need to shout! ;)

New PCV update reroutes airflow in the PCV system to help move things along...

Also...I've been saying this a lot lately, but that's just the way it is:


hose and check valve (labeled "c") - perhaps this has perished on your vehicle...This goes from the TB to he crankcase...I would check that that valve allows flow from crank to TB and stops flow in the other direction...

While this may not stop your leak if you fix it...If it is broken, you are pressurizing your crankcase with the turbo...Sure to cause leaks!

Hey lpalma121,

We're not really fans of attitude around here. Probably why we were short tempered with you when you came here asking this question the way you did without doing your due diligence and looking through the easily-searchable answers to all these questions.

And we're still trying to help you. So calm down.

I see you didn't do any of the research I suggested to you. Let me go ahead and just give you the direct link. All you have to do is click:

http://www.genuinesaab.com/psi/files2/tsb210-2417ed4%20en.pdf

This is a step-by-step howto on installing the PCV #6 kit. This will also give you a good idea if your DIY skills are up to the task. There is one little thing you should do though, before buying this kit. Search here or call a Saab dealer and verify that this correction applies to your 1996 9-5. The service document I linked above refers to the 9-5 MY98-00. It probably applies, but I can't be positive... and I draw the line at making other peoples' phone calls for them. Good luck.

I checked out the pvc valve and it only flows in one direction like it's suppose to but when I blow on it(don't laugh) it feels restricted. I did this test with my 900 and it blows more freely. This almost felt like I was blowing into a clogged straw so I think this may be it or someting related to the system. With this new update I think the valve is included.

As you can tell ... you won't get much from this group like this. :nono;

And you will find that threads will get off topic.
This is the internet and that will happen.
Besides, it was a totally relevant question.

Now this is more like it.

Please remember that everyone is here because they want to be.
And you can see by the responses, you get a lot more help like this.
A lot of people here will bend over backwards to help you out ... give them a chance.

Ok I will give some background. Im a Saab master tech and run my dealerships workshop. I have been working on Saabs for over 8 years. When I started at the dealer in 2000 I was astounded by how many turbos were changed (prob about 3 smokey units a day). This raised my eye brows somewhat. From this time I took very close notice of PCV systems etc.
We found there was 2 things that killed turbo's
Oil starvation from blocked pick up's
Crankcase pressure from pcv failure.
After we addressed these issues within our dealership with our customers now we might have 1 turbo every 3 months.

Now back to my opinion of crankcase mod being a waste of money. I mentioned it on another Saab forum and was overwhelmed by the people that agreed with me on the mod increasing oil consumption.
Essentially the design adds a hose on the recirculation hose (the one that feeds vapours from oil trap back to tuirbo inlet) that runs to the dipstick.
This allows the engine to pull crankcase gases straight up through the dipstick and burn them back into the engine through the turbo.
What this causes is it allows a very large amount of oil vapours be sucked up and burnt. In the factory set up the gases must be sucked through the cam cover (which is baffled and separates the oil vapours and drains it back) then through the oil trap which again separates the oil. When it follows this path a much higher percentage of oil vapours are returned to the sump thus reducing oil consumption and smoke.
Its my opinion supported well by my explaination and supported at my dealership after proving it time and time again on customers cars, we dont even stock the #6 kit anymore.
I had a 98 9-5 that used 1lt per 1000km with #6, reverted back to factory set up dropped to .5lt per 1000km (hey its still a 9-5 they all use oil)

Hope you follow

Cheers

Thanks for that detailed explanation, L4staero! The question that follows, of course, is:

"What, then, do you do to rectify the problem that PCV #6 aimed to solve?"

(i.e., the overpressurization-induced oil leakage around the timing chain cover, etc.)

You've got me sitting here thinking about ripping the PCV#6 out of my Viggen...

Not knocking the explaination, but I wouldn't start doing anything based on one person's comments.

This is something that has been going on for some time now and this is the first thing we have heard suggesting it isn't good for our cars.

I would recommend that perhaps a new thread be started and we discuss this further.
Let some of the other experts and professionals chime in here.

Of course. I tend to add a little flair to my closing sentence, that's all. But I am very interested in hearing his answer to my followup question.

After all, I'm still not convinced that lowered oil consumption is worth undoing the mod. I don't mind consuming oil. That is unless someone can tell me that it's going to cake up my turbine over time or something. In the meantime, consumption sounds like the lesser of two evils.

I do want L4staero to know I'm seriously interested in pursuing this further. And I'll sure as hell move on his suggestion if it outmerits all the consensus I've read thus far during my time here. It will take a lot to do so, but he's off to a good start...

I would guess it depends on the timeline for his observations. The original PCV mod was to drill a hole in the oil filler tube and connect a tee into the turbo intake line and then connect that third hose to the oil fill tube. This was done without check valves and obviously could create quite a mess.

PCV #6 has the check valves which, in my opinion, would reduce or eliminate oil consumption through the crank case breather system.

Now, I'm not going to try to undercut someone elses credentials, because they far outweigh my backyard status, my statement is based on logic and after seeing the changes from the original to this one on the 99 9-5 I installed this in a few days ago. I can see why it is an improvement (as long as the check valves don't fail :) ).

I updated my 1999 9-5 about 20,000 kms ago when I did a bunch of other work to the engine ... no change in oil consumption (which was 0 btw).

Also, I have to wonder what the impact is to all of the newer 9-5's that come from the factory like this.
My 2005 9-5 Aero has no oil consumption (115,000 miles on it), properly maintained since day 1.

I'm not a mechanic but I have to believe that the designers within Saab know a little something about what they are doing.

But this is all good discussion.
