$298.95 non-discounted. If you read the promo, it sounds like a winner. OilGuard might be able to get it at a discount, they deal with Racor. I'll try and remember to call them tomorrow.

I haven't seen any instructions, or parts list to this filter, but I'm thinking my old OilGuard return fitting (oilpan drain plug) would fit the bill.

Maybe OILGUARD has something like this????
I want to remove the crankcase fumes from the intake and burn them in the exhaust. Apparently, the problem is there is too much back pressure in the exhaust to 'suck' the crankcase fumes out.

The Racor system is a closed crankcase ventilation system (CCV4500). It doesn't vent to the atmosphere, and doesn't vent to the intake like the stock system. It accumulates the crankcase oil vapors, and traps them in a filter, returning the trapped oil back to the crankcase.
If it works as well as Racor would have you believe, it's a good thing (credit due to Martha Stewart). From my research so far the unit runs around $200 discounted.

The link I clicked on describes the gases being directed into the intake....just like the stock system. Now the filtered oil does get run into the crankcase, but there is still some oil fumes getting into the turbo intake. The question is whether this CCV 4500 filter is 'better' at filtering out oil vapors than the stock filter (the stock design does have a filter too before the intake, just like the CCV 4500). Maybe double filtering helps? I suppose it couldn't hurt, but $200 for another experiment? I dunno.

I could read it again, but I think the purpose of the intake vacumn is to evacuate the crankcase of vapors, and the filter traps the vapors before they reach the intake. The vapors condense in the filter, and settle in the bottom of the canister, whereby it is returned to the crankcase. This is controlled by a valve in the system limiting the vacumn so it doesn't draw vapors into the intake.
On the factory system,the CCV filter on the valve cover is a simple design meant to trap as much vapors as possible, and condense them before they reach the turbo inlet.
There's a lot to read on the subject in other forums, and this type of filter seems to be popular on Marine engines, and generators. I value my $200 dollars as much as the next guy, but if this works as stated, it keeps the intake clean, returns oil to the crankcase that would normally be lost into the intake, and it's also environmentally more responsible then venting to the atmosphere

Man, I have been visiting, bookmarking, copy/pasting, saving and printing for 12 hours now! This site (and all you FORD diesel-heads) are just phat cats, I mean 4 leaf clover growers, and grimey angels from heaven! It's now 5:30 AM so I guess I ought to catch a few zzzzzs.
But before I do I MUST ask a stupid question that probably was answered and I missed - is this issue pertinent to an 03/2003 build date? (affects 03's as well as the 04's)?
good day!

Mann/Hummel makes a CCV filter that allows for the collection of the filtered oil when plumbed into the CCV line, to be drained as appropriate. The oil in the intake causes major plugging over time combined with the soot from the EGR. I installed one on my '05 VW Passat TDI a while back but haven't checked it lately for how much oil it has collected so far. Wasn't too difficult on the Passat. I may check into doing this on my 6.0L.

Venting the crankcase to the atmosphere makes your truck illegal. I don't care myself, but remember the first smog devices were positive crankcase ventilation systems?
In some areas you could be creating a problem for yourself.
As an alternative, you might reroute it into a cannister with a screen or filter inside and then right back up to where is normally goes. If the cannister is mounted down low it would help capture the oil. Also make it as large an you can to reduce the velocity of the gasses so it doesn't just blow on through.

I finally did the reroute on my 6.0L. I mounted a CCV4500 to the passenger side frame and ran 1" hoses down to it between the crankcase and turbo inlet. I also installed a digital pressure gauge to monitor the crankcase pressure.
When I get on it (WOT), the pressure drops on the crankcase by only about 0.3 inMg. Otherwise, it stays at atmospheric pressure. So my gauge is basically a weather barometer.
I doubt that it is illegal to vent your crankcase to atmosphere. For example, the dodge cummins come from the dealer that way. I vented mine to atmosphere for a few months until I installed the CCV4500.

Really new here, but not afraid to ask a stupid question. I'm very unfamiliar with the fuel system on the PSDs but I've done dynotuning on Mustangs and other cars with MAFs. On those cars when you open the crankcase to atmosphere it will make the Air/Fuel mixture richer because the air escaping to atmosphere has already passed through the MAF. This metered air and is not ending-up in the combustion chamber but the fuel system thinks that's where it's going and puts in fuel as if it was indeed, going to be burned. Many times the long and short-term fuel trims will correct for this, but it still is not optimal, by any means, because the amount of blowthrough is not at all consistant. I've seen it effect driveabliliy and fuel mileage. Is there something about the PSD that I'm not aware of where this would not apply?
