FordGeek Posted August 20, 2009 Report Share Posted August 20, 2009 Hello all. Given my first hand experience with severe blow by in my 2007, I went ahead and installed a Steeda oil separator on my 2010 just to keep the SC intake as clean as possible, and to prevent the intercooler from getting fouled up with atomized oil. I could have put one together for half the cost by taking a trip to Home Depot or Lowe's, but I was too lazy and just bought the Steeda. I have enclosed some pictures for your reference, and you'll notice in one of them that the supercharger end of the PCV coupling is already covered in fresh oil. So, the sooner you get this done the less crap that will get into your intake and intercooler. It's a very simple install and it will only take the better part of 20 minutes to get it done.

In fact, all cars have a bit of it; but supercharged and turbocharged engines are more prone to it due to the pressure gradients created by forced induction. I swapped out the stock Eaton on my 2007 with a KB at 1200 miles and the intake was just a nasty mess. You'll get more, of course, if you do any kind of "spirited" driving; which I do plenty of. After having this past experience, I decided I wouldn't let it happen to my 2010. Link to comment Share on other sites More sharing options...
Wilson Posted August 20, 2009 Report Share Posted August 20, 2009 A simple cheap check valve in the PCV line goes a long way without the need for a seperator. Link to comment Share on other sites More sharing options...

Usually the fluid or air itself provides the force for opening and closing. Regards, Jim Link to comment Share on other sites More sharing options...
Torched10 Posted August 20, 2009 Report Share Posted August 20, 2009 Hope you're enjoying your car,finally.By only flowing in one direction does that affect any operation in the PCV system,One would think if there is a problem with blow-by,the factory would put a check valve in,wouldnt they.But then again,why do they continue to put parts in our cars that rust.

Thanks. This is the best car I have ever owned and I hope to have it for a very long time. I have no idea why they do anything, I am not very mechanically inclined. I know a lot about valves from my time working on tankers carrying petroleum products but relatively little on engines. I am going to have my brother-in-law take care of the rusty pumpkin, he has a small body shop and he is currently repainting my '88 mustang GT Vert.

FordGeek Posted August 20, 2009 Author Report Share Posted August 20, 2009 Check valves will not work under boost because they will open to allow flow from the crankcase, through the valve cover, and into the intake. There is no air heading back from the supercharger to the PCV valve under WOT. So, a catch can (separator) assures you grab any atomized oil from the air stream.

clark17357 Posted August 21, 2009 Report Share Posted August 21, 2009 Most would agree that the GT500 should have come standard with the separator. It is a simple install and has no downside (assuming you empty it when needed). The Steeda unit looks like what came as part of my KB install at SAI.

When installed in the correct direction it slams shut under boost. This keeps the real issue at bay, which is boost pressure running through the crankcase. With a check valve installed the correct way, all you will have is the same amount of blow by as an NA car. Now for the best of both worlds you could do a check valve AND a seperator, but the small amount of oil ingested under non-boost driving isn't a real concern IMO on a well maintained car.

No you're wrong, the extra blowby doesn't come from the blower through the PCV system, it comes via the rings and valve guides. Check valve won't work, but a seperator will.

Ultimately ends up in pcv and into intake I will not argue further, lol. Link to comment Share on other sites More sharing options...
ItalianStallion Posted August 21, 2009 Report Share Posted August 21, 2009 Does Steeda have replacement filters for their setup, or is this filter good indefinately. I would guess that over a quick period of time this filter will be soaked. ItalianStallion Link to comment Share on other sites More sharing options...

War Eagle Posted August 21, 2009 Report Share Posted August 21, 2009 I am not a very good automobile mechanic but i can overhaul an aircraft engine. I am a little confused about the description of what this part does. I have always installed air-oil-seperators on my aircraft as they reduce oil consumption and keep the floor of the hangar clean. When an aircraft engine runs even on an engine with good valves and rings you get some blowby which is normal. The crankcase is always "pressurized" when the engine is running and some oil can escape thru the crank case vent tube along with crankcase vapors. The seperator collects the oil and sends it back to the crankcase and the vapors then vent outside the aircraft. If you are getting oil coming from the crankcase into the combustion chamber then it would seem to me that there is a problem with the engine. Is there a diagram that shows how this GT500 part works and where the oil it is intercepting is coming from and where it is going if not intercepted. I would also imagine that the amount captured would be a direct reflection on the condition of the engine. I just like to thorougly understand what something does before I change the factory configuration of an engine. Thanks for the help, Edit: Also does this part increase the crankcase pressure when installed or is it free flow. Steve Link to comment Share on other sites More sharing options...

Quite a few folks have installed the separater and have revealed pics of the resultant oil this part picks up. As some have changed over their SC or had the originals off, Its apparent a bit of oil does precipitate into the upper air track. I'll be getting this Steeda part.

SmellSoGood Posted August 21, 2009 Report Share Posted August 21, 2009 Why not opt for a larger unit than that 1/2 a shotglass Steeda at $70? You can get a Jaz or BKU for $40 more and dump it out when needed rather than once per week? I'm curious as to the other options out there that may cost more money, but are also bigger and shinier. Who know's the hose diameters? Link to comment Share on other sites More sharing options...
Torched10 Posted August 21, 2009 Report Share Posted August 21, 2009 How much? $79 + shipping/handling of around $10--i will await War Eagle question being answered though before i put it in. Link to comment Share on other sites More sharing options...
SmellSoGood Posted August 21, 2009 Report Share Posted August 21, 2009 $79 + shipping/handling of around $10--i will await War Eagle question being answered though before i put it in. It looks like this unit is circulating dirty air back into the car and doesn't use a breather with catch can approach. Link to comment Share on other sites More sharing options...
LuisA Posted August 21, 2009 Report Share Posted August 21, 2009 The Steeda unit looks like a regular filter with a Coalescing filter element inside of it. The filter centrifuges the oil droplets from the air and the very small droplets that do not fall off via the centrifuge effect, are trapped by the coalescing element. It works, but I agree that a regular filter like this looks awafull. Link to comment Share on other sites More sharing options...

Torched10 Posted August 21, 2009 Report Share Posted August 21, 2009 Another question, does the SC use this blowby oil for any peurpose,like lubrication.I agree it looks awful,and I do have an extended warranty so not sure why Im doing this--but the parts been ordered Link to comment Share on other sites More sharing options...

FordGeek Posted August 21, 2009 Author Report Share Posted August 21, 2009 It's all a matter of personal taste. The Steeda, like I said, isn't anything special and you can pull the parts together from your local Home Depot or Lowe's Hardware. Some think it isn't pretty; but I'm not into the aesthetics. I considered the larger ones, but you'll have to attach brackets to hold them either on the firewall or the passenger side strut tower; never mind hoses running back and forth; this IMO is uglier than a simple inline catch can.
