Will somebody please explain this separator situation for me? Where should I be looking to see if I have oil in my intake - after the throttle body? What do I do if I have oil in my intake? New PCV valve, oil separator? I have found some posts on it in the archives; does anyone have a link on how to build the oil separator, and does it really work? Thanks again guys...

best working kit around.

 

As to whether it is the "best working kit around" that remains to be seen. Guys have reported here and at other L related boards that the Swanson Kit is not a cure by any means. Some Swanson Kit users still report oil problems...

 

I have had the Swanson kit on for almost one year and still no oil in the intake. Boost hits harder and you pick up a few more hp. It might be the best mod that you can do. Skip

 

This is now being asked in another thread, but I want to make sure someone sees my darned question.

Can someone be specific about this kit...say maybe pics or something?


Rocks

I also have the Swanson kit with No Oil to report in last 3 months...

 

ok back to your question.

If you look on your rubber boot from the thottlebody to the MAF, you will notice 2 larger plastic pipe and one small one.

the pipe that goes to the passenger side of the engine is the one that is blocked by the swanson kit.

Oil goes up through the stock PCV valve and into the hose.
From there it runs up to the "whatchamacallit" (forgot the name) on the passenger side of the blower, then out to the boot.

Oil gets into that pipe and ends up in the boot, from there it gets on the throttle butterflies and the intake gets caked with oil.

you can clean it out frequently or do something about it.

Swanson sells a kit (I had it, but took it off) that consists of a new PCV valve and a metal block off plate.

OR there are many vendors that sell catch cans to catch the oil. only bad thing is that yo uhave to drain it.

I got mine from Josh at motorcity mods in Michigan.

Why did I change?
the swanson kit will create pressure on one bank of the engine, but not the other. this can't be good for an engine putting our over 450hp!

Plus where does the oil go? it stays in the tube becuase it can't go past the metal block off plate.

with the "catch can" I see where the oil is and I can throw it out.

other claim the swanson kit adds 8rwhp. NOT POSSIBLE.


the swanson kit stops oil from going into the ruber boot. plain and simple, but there are many ways to stop it.

hope this answers your question

 

There have probabaly been more controversial posts on this subject as any other. Mr Menace gives a good basic overview of whats happening regarding "oil in the throttle area". Almost everyone that did anything about this problem and interestingly enough, not all owners report this problem; have reported success or failure with just about any method tried to stop the oil from gathering in the intake boot which eventually ending up in the throttle area. What seems to work well for some, doesn't for others. It does seem likely, for the changes made in any method used, that any significant horsepower will be gained. I personally went the oil separator route (there should still be many threads in here on how to do it) and have had good success with it. The "oil separator" method tends to keep the heavier droplets of oil from being drawn in though the PCV system, and I think least disturbs any original design intent of the PCV System on the Lightning. And for most of us using this method, seems to do a good job. It does means cleaning the filter housing of excess oil, and cleaning the filter now and then - but it's only a 5 minute job.

 

I made my own oil separator kit 10$ parts . no oil in throttlebody works for m e

 

If you put the disk in the hose leading to the intake boot you put it in the WRONG hose. It goes in the hose behind that one on the upper intake. No wonder it did not work. You have only one crankcase, not a right and a left, so there is NO way you can build pressure on just one side of the engine. The reason that the Swanson kit makes more power is that it stops boost from being bled off through the hose. Everyone that has put one in as said that there truck felt stronger and jumped into boost quicker. Sometimes the simple things are the best things. Skip

 

I'll try this one more time since you are having trouble understanding the concept. I already explained it on NLOC.

The oil does not go anywhere. It says in the block where it belongs. The tube does not have oil all in it because the block off disc keeps the Supercharger from sucking oil out of the passenger side valve cover.

What in the world makes you think it creates pressure on one bank?

 

the pipe that goes to the passenger side of the engine is the one that is blocked by the swanson kit.

Wrong, this hose goes to the idle bleed motor, on the upper intake plenum. You do not want to block off this hose at the idle port.

Oil goes up through the stock PCV valve and into the hose.
From there it runs up to the "whatchamacallit" (forgot the name) on the passenger side of the blower, then out to the boot.

The "whatchamacallit" is the upper intake plenum.
This is the hose, coming up from the passagers side PCV and after the "T" where most oil seperators are spliced into. Right were this hose plugs into the upper intake plenum (there is a second port just behind the idle bleed motor) is where you want to insert a simple GENEREIC blocking device. Leave out the seperator there is no longer any air going past the blocking device.

Remember this hose also "T's off" and goes to the upper intake manifold between the intercooler and the upper intake manifold.
IMHO this is FORD's engineering mistake. Why would they create an open loop between the bottom and top of the suppercharger??????? By blocking this hose at the upper intake plenum you close the loop and increase boost. That's right, at any given time, this hose has either boost pressure or vacuum present! The other end of that hose "T's off" goes to the passanger side PCV !!! Vacuum isn't the problem, it's when boost is present that EXECESSIVE AIR is forced backwards through the PCV on the passanger side and out the driver side valve cover along with some OIL into the rubber intake boot and other places!!!!! The solution is a GENERIC PCV that is a better one way valve. I've heard that a cober PCV will work.

It would seem because a Vender came up with this solution, some posters continully guestion then refuse to understand the concept when it's explained. For those of us that get it, save some money on an oil seperator. Sorry, most of us don't care who gets "CREDIT" for this solution. We can use our brains, install the GENERIC parts and all us non-venders are winners!!! Oh yes, this mod will never need attention and look totally stock.

No Surpise,

Here is a pic of the passenger side tube. The 03 Cobra PCV is the one used in the Swanson Kit. I think it is about $4.95 at a dealership. I believe the tube that T's off going to the lower intake galley has a smaller hole in an orifice the tube plugs into at the bottom of the galley. The pressure that comes back through to the valve cover should be blocked off by the new PCV that will completely close unlike the stock PCV.

A dime can be shoved into the top hose but it is really tight. The hose tapers down in size so anything you use stays aligned properly.





I have had the Swanson kit installed for 8,000 miles and several months. I installed it not long before I had my head gasket replaced. While they had it apart I had them clean the upper and lower intakes. It has stayed clean from then on. I had so much oil in my upper intake plenum it was running forward getting on the back of the T/B blade. Here is a pic 5,000 miles after it was cleaned.

 

Yes, that's the one. In stock form as boost is created the pressure will cause air to flow from the upper intake manifold(under the intercooler) through this hose into the intake plenum, then back through the supercharger and intercooler. See, an open loop !! Unpluge the hose from the plenum (right behind the idle bleed motor) and install a blocking device. Pluge the hose back in. You have now finished half the mod. Replace the stock PCV with the 03 cobra one. Your mod is complete. Remember, we all know who's idea this was. If you reward him by purchasing his KIT, great. As everyone that has installed it CORRECTLY knows, it works. Enjoy your new found boost.
