    There is a problem with the 4.6L and I would imagine just about any other engine.
    The PCV system pulls atomized oil into the intake to burn it during the combustion cycle.
    Normally this would not be a problem and how much it is can be debated.
    But the results are shown below and I cannot see how this can be a good thing in any way.
    So how do I correct this?
    Let me first give credit where credit is due.
    Steeda makes a nice little kit to do the same as I am doing here.
    A PCV Oil Separator kit.
    But myself being the cheap bastard I am saw this and said:
    "I can do that"
    So here we begin...
    The pic below is of the CMCV plates during a delete job.
    As you can see the oil has burned and could eventually gum up the CMCV's on my S-197 4.6L.
    Either way that's a lot of crap I don't need in my intake system.
    [​IMG]
    So let me start out by gathering what I think I might need.
    Below I have a Husky Compressed air filter (5 Micron) from the local hardware store, 4 ft of 1/2" heater hose,
    two brass 1/4" X 2" nipples, and four screw clamps.
    Total cost $24.00.
    [​IMG]
    Below is the stock setup installed and removed.
    [​IMG][​IMG]
    Now Steeda remotely mounts this but since I am dealing with a stock setup air filter I don't have the room
    to mount this anywhere convenient. The choice is yours.
    Also with my setup I don't need to manufacture a mount for the filter.
    So I decided to take the in-line approach.
    I also found I did not need the second nipple or all the hose.
    Ahh the cost of R&D...
    Anyway I cut one of the nipples in half and put them into the filter.
    Remember the filter flow is towards the intake.
    Make sure you put your filter arrow pointing to the intake side.
    Here is the installed filter and hoses in the position I chose.
    [​IMG]
    I did add an Adel Clamp (40 cents) to the hose and screwed it into the air box to keep the hose in place.
    Also insure the loop back of the hose from the valve cover is enough as to not kink it.
    And here is another view of the filter itself.
    [​IMG]
    Plenty of room to unscrew the bowl now and then and dump out the collected oil.
    Problem Solved.
    Well what are you waiting for???
    Get Er Done!!!!

    Great artical and the pics illustrate the process. The heater hose is not rated for oil and will deteriorate. You should use oil rated hose.

    I have the same oil seperator, but I need to get a better hose. Mine has been on for about 6 or 7 days now, and look at how much oil it has already.

    I bought an extra hose from McRee ($25), cut off the spongy hose cover and the plastic hose, and used the factory quick connects to connect the Air/Oil Filter to the engine. I also ordered the brass elbow fittings ($3) to replace the chintzy plastic ones that came with the Steeda filter (~$85). I also used a piece of PCV hose from O'reilly's ($2). Total was ~$115.

    Just drained it again: 617 miles, and just under 2 US teaspoons (just for clarification purposes, there are 3 US teaspoons in a US tablespoon, or in metric terms 5 ml in a US teaspoon, probably 9 ml per 600 mi.

    Looks good. What size hose did you use? I'm looking to change mine. I like the idea of the QD.

    Not sure what the size is, it was labeled as crank case ventilation hose at O'rillies (sp?), and it fits perfectly over the threaded side of the elbow barb, and I applied some tape-style silicon and a hose clamp for good measure. See pic for approximate ID/OD size.

    I also included a pic of the bag the elbows I used came in, for ease of ordering.

    Travelers, I believe you're the one that got me going on this mod...when I say it in your sig.

    I remember. I do like the use of the Q/D on the PVC system thats why I'm going to change mine. I'll have to find a O'Rillies aournd here. Thanks

    The ford dealker didn't have the hose with the QD in stoick...I had to pay for it ($25) and order it, and it took about a week for it to get here. Then, carefully slice the (relatively) hard plastic off the QDisconnectors, but BE CAREFUL!! There is a blue O-ring on the male barb of the QD, which you want to preserve, so be careful not to cut it. What I did was get the slice going at the bottom, and then I literally tore the plastic off until I'd gotten past the blue O-ring. Good luck!

    BTW, save the pics if you want to refer back to them, because I'll need to delete them in order to post more pics due to the new limitations.

    Guys,

    As long as you're installing one of these units, I've got a couple more suggestions:

    1)
    I paid around $12 for mine. It was so cheap I decided to do a little experiment. I wanted to see how much oil was NOT being captured so I installed a pair in series. I did this on my '03 Terminator when I owned it. Guess what? Each trapped the same amount of oil (see pic)! I can't help but wonder how much is still being passed through....

    2)
    If you're using full synthetic oil, remove the white "filter" like I've done. It is not compatible with synthetic oil.


    other side?

    On the Terminator, I've read the passenger side passes a minute amount of oil. On my S197, I wasn't sure so I installed a pair, similar to my Terminator. After 4,000 miles, take a look to see how much oil was captured. Hardly any at all. For the same mileage, my catch can (driver's side) has trapped almost one inch of oil.

    thats why if you go with a unit like the stefs unit you wont have additional problems. its the nature of the design. works liek a charm and holds massive amounts of oil . intake hose is lined with oily residue. hose gonig to manifold? perfectly dry

    Willie: Which catch can do you have in your S197 (red?) Can you drain your driver side catch can and measure how much oil it caught? I suggest you use a medicine cup (nyquil, etc). I catch ~2 teaspons every 600 miles; I'm interested to see how that comapres to your quantity over 4000 miles.

    And what do you mean about the white filter no being compatible with syn oil? Please explain.

    Thanks

    I fabbed my own catch can. It's basically a modified CSR catch can I bought from Summit. I shortened it, added a sight tube,and tapped 3/8" NPT threads, to accept two 5/8" hose elbows. Yes, it has a drain petcock on the bottom. Certainly I can measure the amount held today but I'm not accurate on the mileage. The 4,000 miles was a "best guestimate".

    Before I installed these separators, I read a couple of times on SVT Performance that the white filter is not compatible with full synthetic oil and followed the suggestion and removed it. It is pictured in the red ellipse. Notice in my pic that mine don't have the filter.

    Ok i understand, but what confuses me is that the filter is in fact the coalescing element for the air/oil separator...

    hey all,

    just registered on this forum its a nice one.. sorry for being dumb.

    but this seems interesting, what is the advantages of this ? I mean will it help keep my power or does it make my engine healthy ?

    also is it the same as an oil cach ?

    it is an oil catch can. separates the oil mist from the air so that it doesn't get sucked into the manifold, decreasing the efficiency of your inter cooler, and decreasing your octane rati9ng of your gas

    Ordered the Moroso unit with the Moroso bracket, and the fittings from Earl's directly:

    Moroso Air Oil Separator: MOR-84571 $97
    Moroso Mounting Bracket: MOR63401 $7
    S&H: $11

    Earl's Part #9892120 AN-12 Female to AN-10 Male reducer (2x$15.35)
    Earl's Part #700111 AN-10 to 5/8" straight push lock hose end ($5.88)
    Earl's Part #712011 AN-10 to 5/8" 120º push lock hose end ($25.78) OUCH!
    S&H $9

    This setup doesn't use the braided lines...regular PCV hose (5/8"). We'll see if the downstream side becomes as dry as y'all claim!

    and since :worth:,

    I'll post them as soon as I get and install the stuff...
