hehe i guess there is now way around it ;p btw anyon can answer the questions to the return lines for a oil catch can? the 06's are a bit different than 05's and 04's

Return line to the intake after the MAF; the send line from the crank case vent.

The Jet Air Mix from the boosted side (on the last pipe) and OMP on the 2nd nipple on the greddy intake pipe (or vice versa - I can never remember). Then cap the two nipples on the IUM.

That is how my 2007 is wired.


Best pic I got:

 

Thanks Kane I'll take a good look at it and try to figure it out hehe

 

Call me at eight 0 eight; 398-10 sixty four if you need more help.

 

Ok, let me confirm. I am still a bit sketchy where as i can't see exactly where everything goes in the picture. I think I got most of it right, but I want to confirm. Where did the hose originally go to, before it was attached to the oil catch can? I can't seem to follow it far enough, it goes deep down in the engine bay. I'm assuming i unhook that hose and connect a hose from the oil cap to the catch can. Then the other nipple on the catch can goes back to where the hose was originally connected to? (My oil catch can has two nipples) The other hose seem to be going to the right place. ( nipples after the maf sensor) I do never connected to a nipple on the intake (before the maf) like most people originally did. Did a quick draw to confrim. Thanks again for any input.

 

Your line to catch can is correct; that hose is conected to those 2 nipples on the side of your UIM; right?

Run from there and over to a nipple after the MAF; preferably the one that is not being used - OR being used as the oil line already. In my case; one of them was running from the back of the oil filler neck (I have another nipple back there)...

 

Ok, when I get off work I'll take a second look and probably put the bottom stock airbox tray back on, so I can bolt on the catch can. Will update. Thanks again

 

isn't the oil catch can just to keep oil from entering your turbo and intercooler? on the updated models the oil lines go to the UIM so there isn't really a need for a catch can like earlier models that routed to the intake tube.

 

ditch the greddy maf housing. When I did it fixed the problem of rich in boost. Just get a 3.5" OD pipe and replace your greddy maf and that pipe in front of it. drill the 1" hole in the middle of the new pipe and mount your maf there. Get a 45 degree silicone coupler for just after the maf, and whatever is inside the bumper to fit your new 3.5"

 

I think the oil catch can is used to prevent oil from going in to the intake. I could be wrong though. I figured something was weird when I was trying to figure out the hoses when I compared my car to an 04 05 model. Not sure if I don't need it, can anyone confirm this?

Grouch, I am trying to get to your diy, just time hasn't permited me to fabricate the certain piping I need.

Kane, is your piping powdercoated? I would like to do something similar. Please let me know if you did it yourself, if so how did that go. Thanks

 

Yes; you still do.

The can is used to prevent oil vapors from going back into your engine intake track; regardless of where the stock set up sends it (UIM vs Intake).

You don't want old nasty oil condensation in your intake tract.

 

Yes; my piping is powdercoated (high temp; the good stuff)

I had it done; but it was all but free from a buddy of mine. I think you would pay very little to get it done even without a hook up <$100.

 

do you think you can still do this? i found a place that sells them but they are charging $315. http://www.yourperformancesource.com...-Through..html

 

yeah i guess the biggest thing is finding the adapter flange to mount the MAF on a piece of tubing. it is kind of nice to have those flared edges too though.

 

charles, could you get me the parts to have this made?

 

I just connected the other end of my catch to a breather. That's how I have it. Why recirculate the oil back through your intake to clog things up!
Also, just found a chrome 3.5" exhaust pipe at pepboys for 20 bucks, it's about a foot long. going to cut into the pipe and make my own CAI following these directions

 

AEM CAI can also work.

 

i talked to greg today and he also mentioned using the AEM

anyone here actually using it though?

 

yes, a few are.

 

so would it be simpler to go with the AEM instead of using this DIY?

 

ask alienRX8 to snap some pics and post a DIY

 

The 'old' (v.1) version of the K&N intake came with a perfect tube.....

S

 

I will be when i go home to put it all together. Little birdies have told me its a great simple anf functional solution

+1 although i dont see it being very difficult to figure out

Anyone know offhand if the MS3 AEM CAI has the same piping as ours? If so I'm going to get one of these.
