Well as you guys may know my car has been losing 1.5-2 qts oil every 1500 miles or so. I got a Ixiz air oil separator to see if it helps from blow by. I install the kit and triple check everything. Even called two people who have it to make sure I have it right. Go for a drive and over 5 psi boost blue smoke coming out the exhaust. CRAP! So I limp back to the house and turn off the car. Double check everything....it's fine. Crank up car and smoke immediately billows out. CRAP engine is blown I think. As a last resort I return back to the previous setup. Crank up the car and smoke. Realizing that there is still smoke and maybe oil in the system I go for a drive. Looking out the mirror I see a little smoke, then a little less, then nothing. WOT I go......NOTHING. Get home nothing. Let car sit and fire it back up NOTHING....smoke free. Hmmmmm what gives. Is it finally allowing my system to work 'properly' therefore the real problem is now evident? I dunno....what does WRXAtl think? Oh and this week when it is not raining when I get home I'm compression testing the car again to see what it looks like. Can't wait to get this money in so I can build this 2.5.....hurry up IRS!!!
Dang talk about customer service....Ming answered my email and tells me to call him. He thinks I have a lot of leftover oil in the intake and manifold and FMIC. The added vacumm this system makes is pulling the oil and burning it off. When it dries up I'm pulling the FMIC to clean it. Seafoaming the car, changing the oil, compression testing, then changing spark plugs. Wondering if it is even worth doing with a new engine coming in the next few months....
Oh it's eating oil alright. It's NEVER smoked before until I installed this A/O Separator. Now it smokes like a freight train....took it off and no more smoke.
Well I just got off the phone with IRS and my money was mailed out Friday. It will be here any day. Pshhht I'm not touching ANYTHING on this engine now. Just keep adding oil. Just keep adding, just keep adding, just keiep adding adding adding....okay I'll shut up now.
My only thoughts would be that the AOS has inadequate flow through it or more restriction then the stock system causing more crank case pressure (in your case) which in turn causes alot more oil to be pushed pass the rings... at least that's the only explanation that makes any sense to me.
You think it's possible the stock PCV isn't sealing as well (sticking) therefore allowing me to build little crank pressure? Where the AOS seals perfect and doing what you said? I wish I could test it. Would like to know for sure. I'm a little hesistant putting this AOS on the new motor now!
No because more crank case pressue = more smoke. So if the stock one was allowing more pressure in the crankcase then it would have smoked all to hell.
It smoked this morning on startup in a nice big puff. Then stopped. Didn't boost it at all though.....scared to.
This morning no smoke at all on stock setup. Now knowing my money is soon here I said to myself forget it and I boosted the car WOT. NOTHING and it pulled hard like always. I'm not confident in this kit as of now.....either something isn't right or I hooked it up wrong. SS is sending me pics of how another car has it plumbed.
Yeah, probably sending you pics of my car since he has it up there with him and it has the same setup on installed by Ming
Yeah I called him and said since yours is there can he send pics. Hope you don't mind (which is why I didn't say your name). Wanting to double check it.
Hmmmm after more and more research I 'think' I hooked it up wrong. Now that I think about it and lay it all out it makes sense. My dumb butt was boosting into the crankcase! I didn't cap off the throttlebody line. I tee'd it into the other two lines thinking it will shut off but duh it would just reroute into the crankcase or into the A/O sep. Stupid stupid stupid! Redoing it tonight!
i dont want to lock your post by posting (has happened before) in future its always best to contact the manufacturer directly - unless they arent solving your issue or not available (neither of those has happened) Your solution is in the email You are not only boosting into the crankcase but also at idle you are pulling oil from your crankcase and AOS into your intake manifold
Delette, I wish I had pictures of mine (I actually may somewhere, but can't find them). We ditched the ugly rubber hoses and went with braided stainless, and tee'd the two sides together. Looked really sleek.
Thanks man! I figured it out but I still like where yours is mounted so I want close ups of how that was done. It won't fit near the tower due to the TXS FMIC piping in the way.
You could greatly improve the appeal of your product by not approaching this thread as you already have. Not to digress from the problem at hand, but should be more than fully aware of why your threads are locked. In addition, it would be interesting to see you reply to this thread with the "solution" you emailed. Even though you continue to choose not to support this community as a vendor, your current and future customers would appreciate seeing how you address a product or an installation issue. But hey, that is just basic PR.
The solution was this..... Since I removed the stock PCV I needed to address the boost. I had tee'd in the TB line to the rest of the system not fully thinking it out. Stock PCV has the check valve in between the TB line and the crankcase so at boost it closes. However since I eliminated that I was applying vacuum and boost to the crankcase therefore feeding oil into the AOS which then went into my turbo inlet. That equals the tons of smoke! DOH Delette you STUPID IDIOT! So if you leave the stock PCV you are fine. But if you eliminate it, you need to cap off the TB hose.
Good to know, I appreciate you helping providing the reasoning / method to resolve the problem the you were experiencing. Understood, and that has never been the issue. I frequently receive phone calls and PMs about your products and their issues from your customers. Whether or not they contact you about it I have no idea. I do not make light of the issue because frankly it is not my business. Nevertheless, you should always strive to support your customers and work diligently to rectify the issues that may arise. I am pleased to see that, as a "vendor", you did just that in this thread. I am sure coolrex appreciate its. The thread was not locked by myself or any of the moderation staff for one reason: You are not advertising your products within it.
I do appreciate the help. Reason I posted this is that it allows others that may make the same mistake to see this and resolve their issue without having to ask the manufacturer.
Reinstalled last night WITHOUT tee'ing into the TB vac line. Pluged the Vac line and VOILA it works. Better throttle response and more consistant vac. Car feels more driveable. Oh there is oil everywhere...haha. Nice.....
Thanks for that tip Ming....however I am in the middle of ordering a SLEW of 2.5L parts. This EJ205 has my permission to go ahead and DIE!
Since we are talking about PCV valve, may I ask where is it exactly? Is it under the throttle body on all cars or is it right above the block in the y-connector? So if PCV valve is capped versus removed, does it make it a difference to the A/O separator? And if this is what PCV valve looks like, pic from clubwrx what do you replace it with, a simple threaded plug (size pitch and length please)? And is PCV valve on the same location on 04-07 STi?
That is the PCV on a bugeye. On 2004+ it's much different. Look beside the turbo on top of the block. You will see it on top of the crankcase vent.
