"GM has a new pcv valve that is used on their trucks that is suppose to help reduce oil consumption that some customers have complained of. The new pcv valve (GM P/N 12572717) is known as a “fixed orifice” pcv valve. It does not have any internal moving parts, like many pcv valves do, and will not rattle when shaken."
I'd be interested in finding out more about that valve.

doesn't the pcv valve control airflow (mass) by how far it opens? At low idle, blowby is not strong which means the pcv valve will only open slightly. Under heavier engine load, the blowby is greater and the pcv opens wider allowing more airflow (mass) to go thru.
Thus, if vacuum is normal (as determined by MAP and idle), then the PCV is under normal conditions / circumstances to do its job controlling the (mass) ... ???
also, if the blowby is so strong that the pcv cant allow ALLl blowby to escape (or perhaps the catchcan filter is slightly dirty) then the excess goes back thru the breather hose? is that right?
seems like changes in airflow (mass) caused by a filter (gradually over time becoming saturated) would be compensated for at the PCV valve.
thoughts ??
Ok, once and for all, liquids cannot plug this filter. We cannot compare this to an air filter. It is so coarse and stiff it will not plug. The filter element is NOT SOLID, it is just a shell and take a look at the previous photos of a cut away of it.
So please guys, stop saying this filter is going to plug up seeing that any excess in the filter will just drip out and into the vial once you turn your engine off if there is any oil in it at all.
If you have that much blow-by, even a stock system would have a problem with it.
This system does not restrict the PCV line at all. It is made to flow compressed air at over 150psi or the negatice pressure here is practically child's play for it.

Now THAT is what you call a restriction. :lol:
Now you can see that this filter is not a big deal now if GM uses sucha small opening there. ;)

Stock system?
I think the major restriction is probably within the crankcase itself.
Can we downgrade to a $64 question, you are emptying my AF bank account here. :lol:

Holy hell bro, you have more than I have after over 400 miles. Good thing you installed that system, that is one helluva lot of oil going back into the intake.
Also, I noticed where you have the hose going from the filter to the intake. Remove the tubing and have the tube going behind the throttle intake bracket instead of through it just in case it interferes with the throttle cable at all just to be cautious.
Like this.
http://x2.putfile.com/10/28720582351.jpg (http://www.putfile.com)
Also, do you have the filter positioned so the arrow is pointing towards the intake?
Can you show me a pic of where it is attached to the PCV valve?
Make sure you give it lots of slack so the PCV valve sits in its rubber grommet properly. Having not enough slack will have the PCV valve sitting on an angle.

hmm just curious would the oil that the engine burns normally without the catch can make for a slightly oil burning smell in the exhaust, makes sense it would.

Not all of it burns, but a portion will. The rest will accumulate in the upper plenum and drain back into the crankcase where it will contaminate the engine oil faster.

Take a photo os where it is going to the intake so I can see it along with the PCV valve one.
In my pic you can see the slack I have on the hose just before the PCV valve.

There is no path for drainage to flow from the plenum to the crankcase. Once the oil mist reaches th plenum it will stick there or stick in the intake runners or flow into the combustion chambers.
Overall this filter is a good idea if you remember to service it regulaly. I used to think all the black coating in the intakes was from EGR, but now I see that at least some of it is from PCV.

on the cpi 4.3, there are holes in the lower plenum that can allow oil and gas(if cpi is leaking) down into the crankcase.

Please explain how this can be true. If there are holes that would allow oil to drain, the same holes would allow blow-by to flow directly from the crankcase into the plenum. This would short-circuit the PCV system and make it inoperative. If these holes existed they would be a major vacuum leak that would cause additional serious problems. There are no holes in the plenum that connect to the crankcase.
Gasoline from a leaking CPI can reach the crankcase, but it does so through leaky gaskets, or by leaking into the combustion chambers and then leaks past the piston rings to reach the crankcase.

Yes, there are two holes that drain into the two middle cylinder areas of the crankcase.
That is why when the nut kit ruptures you always see a #3 misfire and #3 plug being completely carboned up.

You should remove that old PCV hose and run a new line directly to the hose connection right on the intake.
And yes, you can take it off. Remove it when you engine is warm and you will see that you can easily pull it right off.
It is just a rubber connector up there onto the hose nipple.

Just remember that the stock rubber coupler can be removed as well.
When you have properly removed it, you will be attaching the new hose directly onto a metal hose connection.

What??? Let's start with simple definition. Crankcase= lower end of the block which houses the crankshaft, (thus the name"crankcase") bearings, connecting rods...
If the leaking fuel reaches the #3 plug as you say, then it is not reaching the crankcase. It is leaking into the #3 combustion chamber, (top of the #3 piston). So your example is additional proof that what I posted is correct. There are no hole between plenum and crankcase.

installed my oil catch can tonite. ten minutes tops.
Got a Campbell-Hausfeld filter from WalMart for $11.97. the two fittings for $1.94. The hose was $1.18 at Advance Auto. I bought 3 ft.
I got a 1997 and so the PCV is about 3 inches from the intake connection. I routed mine up from the valve cover, around the master cylinder, back towards the brake booster, and back over to the intake. Didn't even need any cable ties to secure (although I'll keep an eye on it). The filter sits close around the brake booster. Plenty of clearance around hot rad hoses.
First start up, idle was spot-on (left the filter in).
I like to think my engine is pretty clean so it will be interesting to see how much oil accumulates in how much time ...

Yes, there is a purge but you can't use it.
You will have to unscrew it and dump it out like I did every time it gets reasonably full.

If anyone is actually interested in finding out the possible impact of the filter being clogged.
We need to find out the actual SCFM for the PCV.
If anyone knows that we can get the SCFM for the coelesing filter and determine a percentage of plugging that is acceptable.
The fact is that when you are using a filter of any kind particles of debris are trapped in the filter, especially when you are using an oiled filter.
Not just to disagree with LT but I would like to know what the flow is through the PCV before I put anything in front of it.

What is the ID of the tube that is being used?
OH, the other thing is does anyone know the actual vacuum in inches of mercury.
You are getting way to technical about this.
Everyone installs it and has no problems and catches lots of oil and vapor.
Needing all these concrete scientific measurements to take sure a small plunge leads me to believe that you might as well pass on this mod and look into something else..
Everyone here that has installed it has loved it.

The information you are asking can easily be collected by yourself on your engine. The information you require is not the same for all engines and PCV valves from different years.

Of course they are well documented, I created this thread.
I am just saying that the things he is asking is not obtainable through other members seeing different engines and their different PCV systems have different PCV valves, flow rates, and vacuum requirements.
I am sorry if I seemed harsh initially, it wasn't my intention.

the manufacturer's packaging states that the Average Air Flow (based on 100 psi inlet pressure with 5 psi drop) is 24.8 SCFM. It is a 5 Micron filter (meaning it's designed to filter particles of 5 microns or bigger) and the body material is zinc.
I do not know what the SCFM is for our PVC systems. how can it be measured?
can psi be converted to SCFM or ACFM ?
If anyone is actually interested in finding out the possible impact of the filter being clogged.
We need to find out the actual SCFM for the PCV.
If anyone knows that we can get the SCFM for the coelesing filter and determine a percentage of plugging that is acceptable.
The fact is that when you are using a filter of any kind particles of debris are trapped in the filter, especially when you are using an oiled filter.
Not just to disagree with LT but I would like to know what the flow is through the PCV before I put anything in front of it.

I completely understand you hesitations, however, since the filter is a dense, zinc (most likely embedded in carbon) filter (similar to your Brita water filter), it will more likely reduce performance in filtering ability, rather than clog. In other words, that nasty oil vapor schtuff will flow through faster, rather than slower (clog). Also, the o-ring seal will probably loose its efficiency before the filter fails.
thoughts?

5-micron filter? Reminds me of the old bronze or metallic filters we used to use in the carburetor's gas inlet (Quadrajet? Holley?).
I wish I had one in my hands - However, all I know is that filters clog. It is only a matter of how fast. This is a filter that is being used for a purpose that it was not designed for in a system that was not designed for a filter - Also the system that if flow is restricted, crankcase (oil) contamination increases.
I am much too cautious to do this type of mod without having some way to test if the filter is clogging. Maybe replacing the entire unit (if that's what it takes) every 10k or so for peace of mind. Maybe back-flushing the filter with solvent periodically would be enough. I know that the old gasoline filters I mentioned above could not be cleaned by back-flushing. You had to throw them out once you got fuel starvation.
Maybe nothing is ever needed to keep it free-flowing. You guys will find out.

yeah, I agree with most of what you're saying ...
the proof may lie in the PCV SCFM rating ...
I would disagree on the point that the filter is being used for a purpose that it was not designed for ...
the manufacturer's description says that it is "... a general purpose filter [that] is designed to remove most liquid and solid particles from the air supply."
it seems to be doing that satisfactorily ...
at the risk of sounding too "unscientific" ... do not all filters clog or otherwise lose their effeciency? of course they do. Is an engine DESIGNED to run on a perfectly clean, brand-new air filter? what if that air-filter is slowly clogging? after 50 miles? after 100 miles?
what about oil? is a system DESIGNED to run on a brand-new filter? should we be sceptical of that system after 50 miles? after 100 miles?
hmmm ... our air intakes were not DESIGNED with a CAI, "cone-type", 360 degree filter in mind ...
more ideas!! keep 'em coming!!
anyone on SCFM ???????????????????????
would the SCFM of (a particular make/year) a PCV system be the "proof" ???

I would identify a general purpose filter as one not specifically designed for any particular application (purpose is the wrong word). It obviously functions in a high-pressure system ok (compressed air), but I was specifically referring to its use as a filter in the PCV system.

I believe they design engines to run on many restrictions of air and oil filters so that there is no significant problem with using them within recommended change intervals (and beyond). Neither of them is a good analogy to this filter.

I was just thinkin that a 5 micron filter designed for 100psi pressure used in a system that is generating probably like 12inHg might be some cause for concern. Like Brian said this system was not designed to utilize a filter.
While BlazerLT has a great mod here, and I applaud his efforts and innovation, I am a little concerned about the flow restriction in a vacuum system.
What is going to happen if that vacuum level is doubled and flow is cut in half?
See, when dealing with vacuum vs compressed air you have totally different variables.
Typically when you restrict air flow in a pressurized system all you get is less flow. When you restrict flow in a vacuum system you could get increased levels of vacuum as well as reduced flow. Dependant on where the restriction is in the system. So the real question is what is going to happen as a result? Otherwise what do "I" need to do to avoid any restriction? Then I dont need to be concerned with the side effects.
I intend on trying this out once I can convince myself that I can do it without any potential damage.

PSI is a measure of pressure. ACFM and SCFM are measurements of flow. There is no"conversion" factor to equate pressure to flow.
The PCV flow rate of a seasoned 4.3L is in the range of 8-10 ACFM (approx 6-8 SCFM).
24.8 SCFM( at 100 psi) = 3.2 ACFM. If this filter really has 5 psi pressure drop at 3.2 ACFM then it is too restrictive for use as described in this thread.
Those who leave this filter installed can do a reality check by monitoring the oil deposits in the PCV inlet breather line (fresh air inlet hose from air filter to valve cover) and deposits on the throttle butterfly. As flow is restricted in the PCV valve line, blowby will be forced to flow out the inlet and will then be mixed with intake air.
Use a Q-TIP to swab the inside of the inlet breather line. Oily residue would only be there if you are flowing backwards.

If there are no solids in your crankcase, why use an oil filter? The crank puts liquid oil from the sump into the air above the crankcase as a mist containing everything that is in the crankcase, including oil and the solids that you need an oil filter for. This mist is part of what you are sucking up in the PCV system. That is where the solids I am talking about are coming from. There may not be much, but you will never get me to believe they don't exist.
@ZL1power69: I don't expect you will have trouble with the filter element after a week or two of use. I'm talking about years and 10s of thousands of miles from now.
Really - You guys may have a fool-proof system for trapping PCV emissions. I am not going to argue about it further because it's only a possibility I'm raising and I have nothing to back up my concerns except what I envision under worse-case usage. I don't think there is anything further that I can add to this discussion.
True experts are constantly being surprised when they see that something totally unexpected happened in a system they have studied for years and thought they knew everything there is to know about that system. You are only fooling yourselves if you think you "know" something, even in a simple system. I am humble enough to know that I don't "know" everything about much of anything of complexity.
Keep an eye on that trap and Good Luck. It's probably bullet-proof as LT says.

Comon Brian, comparing this system to your oil filter system is not warranted and is unfounded. Solids don't flow up out of the valve cover.
You are really turning this thread negative.
The PCV system recycles gases and fuel and oil vapor, not solids.
If you had solid flying around you valve cover and in your intake wouldn't your whole intake be full of sand after 100,000 miles?
Cleaning the filter every oil change probably wouldn't hurt but really this arguement has gone to far.
Let's drop it and move onto discussing everyone's experience with the mod instead of constantly negatively talking about all the "possible" worse case scenarios.
Hell, even changing your air filter can be just as damaging as this mod.

The gas flowing within your crankcase and flowing out through PCV does contain solids. Proof of this is the grimy deposits that form inside the engine, inside the valve covers and inside the intake plenum. These deposits contain millions of solid particles.
If your engine did not have these solids deposited throughout, then what were you getting rid of with your AutoRX snake oil??

It is a valid comparison. Both are exposed to the crankcase contents. They are both involved in getting rid of unwanted contaminants in the oil. Both are filters.
There are solids in the crankcase mist - and I'm not talking about sand. Don't be ridiculous.
I am trying, apparently in vain, to drop this subject by agreeing to disagree - let it alone. Let people make their own decisions. I am willing to drop this, but do not think you will get me to agree with you or to allow you to make such illogical statements without challenge, such as using issues like sand in the valve covers and changing air filters. Exagerations and poor analogies will get you nowhere. It is only an insult to me to see you make such statements, obviously without thinking about what I am saying.

There are solids in the crankcase mist - and I'm not talking about sand. Don't be ridiculous.
I am trying, apparently in vain, to drop this subject by agreeing to disagree - let it alone. Let people make their own decisions. I am willing to drop this, but do not think you will get me to agree with you or to allow you to make such illogical statements without challenge, such as using issues like sand in the valve covers and changing air filters. Exagerations and poor analogies will get you nowhere. It is only an insult to me to see you make such statements, obviously without thinking about what I am saying.

The gas flowing within your crankcase and flowing out through PCV does contain solids. Proof of this is the grimy deposits that form inside the engine, inside the valve covers and inside the intake plenum. These deposits contain millions of solid particles.
If your engine did not have these solids deposited throughout, then what were you getting rid of with your AutoRX snake oil??
Just looked at my filter will over 1000 miles on it.
Nope, none of these supposed solid plugging it up.
Why are people hypothetically arguing their point when they don't even have it installed or oven looked at the filter. Ask all the guys that have installed it and see if this filter is clogging up with this phantom solids that everyone is bringing up, yet doesn't seem to be in the filter I have?
And thanks for the Snake oil remark cheapshot.
