My car doesn't ever stumble. Recirculated BOV, good mechanical condition and great tune mean it drives better than stock.

I don't see why a lack of PCV valve would cause that though...

There are no open vacuum sources. I just have the PCV valve capped off.

I tuned it myself.

O you capped it off.... Lol it sounded like you just removed it and connected... Yah that works too but at low rpms, its a good source of vacuum and shouldn't accumulate oil

^^ Concerning the "T" I have one -10 AN fitting welded in its place, it is then routed to a moroso catch can(with breather), and finally routed back to where the stock catch can is vented into the block.

Interesting. Suscribing! I hate the pcv issues with the sr and i have to be carefull as to not rout to the atmosphere in order to prevent fires due to running e-85.
This sounds like it could make my engine a little safer as well as suck in a little less oil.

High G's on 18PSI on a very heavy altitude change course, I had 0 oil where as normal setup with crank to T to catch to Intake, I was filling up in 3-4 laps and this is the greddy large catch can..... Anyways pic will be up Monday.... there is still some work to be done... but Monday!!!



That is the altitude change you are looking at and there is a very sharp crest at the top....

Here is the other... That is top of 3rd coming over this crest and I nearly top 4th.... Not enough down force so over the crest you lose steering a little.....

yeah i would like to see this cause i was gonna run a catch can setup.. the simple left part of the T with a catch can in between the intake pipe and the other one still has the stock oil separator (should i keep the restrictor in the hose or remove it? cause i change hose and didn't throw away that restrictor in it in case i really need it but haven't found any useful info on that...)

I'm curious, are we not worried about blowing out the main seals? I'm assuming all of this comes down to you pressurizing the crank case; under WOT?

Its about maximizing vacuum. You never want positive pressure in your crankcase.

What I dont get is, if your getting that much blow-by (3-4 can fulls), why are you band aiding the problem? You already know what that means, engines going down the shitter. Instead of figuring out how to lessen your blowby, you need to start saving money and get ready to rebuild the bottom end.

Ergh.... I run 18PSI on a 2871R all day on the track.... It has heavy altitude changes as seen in the picture. Ergh, I have already solved 1/2 of the problem which is complete eliminating the blowby. The engine has been full rebuilt from the ground up. Driving on the street and doing the occasional pull gives not a drop of oil in the can.... Its just on the track.....

Ok... pics will be up one day late.... cause I was just too tired while putting on the valve cover and intake stuff back in. Was testing the setup for best results.....

So far with nothing changed except welding bung for pulling in vacuum from the catch can....

So here is a brief description of the setup....

First Phase
Blu808 welded a 90* AN fitting to the top of the valve cover and replaced the T with a 90* AN fitting as well. The AN fitting on top of the valve cover is right next to the words TWIN CAM 16VALVE right next to the "E". We modified the baffling in the valve cover to allow it to "breath" easier and suck gases from the blowby better. So from the crankcase, it goes directly into the 90* fitting that used to be the T. Then from the top of the valve cover 90* it is piped down into the catch can and the catch can to open air. Just this mod eliminated blowby and any oil into my catch can on the track. I had 0 drop of oil in the whole track section and the car felt good....

Second Phase
We finished it last night, because my Alu pipe from PipingPro didn't have a recirculate bung (BOV is circulated though), cause I didn't ask for it for the valve cover, we had to remove it and weld a bung. So now instead of having the open air side of the catch just open to atmosphere, we basically piped it back into the intake now, so the catch is a completely closed system. This part is tricky, because right now at idle it pulls about .6 more PSI at idle based on my Profec-E01 Digital gauge and idles a little higher around 100 RPM higher. From my experiences this messes with the boost settings a little when the base PSI changes a little. It is immediately noticeable that start-up is much easier and reduction in cold start RPM fluctuations which I was getting is basically gone. Now I can't tell too much yet as I haven't really driven on it except to work which is a traffic commute but when I get off work, I can drive it with a little more open road and fix my idle a little more.

Like I said pics up tonight.... But you get the idea

Yah I am still working on making sure everything is running perfectly.... But so far it runs better.... I will take it to the track in April for Laguna Seca.... But at this point all I can do is dyno it and hopefully I can do that in Feb or March.... I hope to come up with revisions to the design.... You can actually pm Blu808 and he can do all the welding and modifications to the valve cover....

(Blu808) Luke can you chime in on pricing....

Probably going to drive a little during lunch too

Well for the pricing. I wouldn't consider this a huge "money maker" so I will do it for a really reasonable price. Say. The cost of the fittings, and like $75 for the tig welding, oil baffle modification, and prep. I can also have the valve cover powder coated or polished.

Basically here is what you would be getting.

1 -8 A/N fitting (male/compression) welded to where the stock T fitting goes.
1 -8 A/N fitting (male/compression) welded on top of the valve cover.
Oil baffle modification
Prep for welding

We can also supply you with either A/N fittings and stainless lines. Or A/N push lock nipples.

Let me know who wants to do this.

Luke

In stock form yes... With this mod no.....

It doesn't have a restrictor on the hose does it? I am not aware there was a restrictor on it... Can you take a pic.....

So in your case crank to AO separator, to T to Catch to intake..... But its not promised your catch with G's and full boost depending on turbo will fill it up.... as this is the way I had it up before....

With this mod from Luke you won't fill it up.

Here's a pic.... sorry about the quality, but from my camera phone.... Didn't have time to clean things up either, but trust me Luke's product will look good!

Nope, had any issues. My car isn't just used to go get milk at the grocery store, so the oil gets hot often enough, and the valve cover is connected to the turbo intake via a catch can which provides way more flow than the stock PCV valve.

Actually, my SR's oil stays clean forever compared to my M3's.
