I did a search and they make a unit as I described...

So, interesting problem after the lines froze up. I have since fixed the problem of the lines being able to freeze, but for the first drive after this fix (this morning on the way to work) I had some issues.

After going under boost some oil would burn off. Not a ton, but enough to leave an unpleasant cloud behind me. Also, I am getting a little white smoke at idle. Not near what it was like with the lines clogged, but still, it is there. Granted it is 15 degrees outside this morning, so the white smoke I am not that worried about, but I am thinking there is a possibility of a bad valve seal. If that valve cover was pressurized enough then it might have caused a seal issue in there... not sure.

It was never driven with the breathers clogged, just idled for around 15 mins that morning. So, long term problem or are we thinking it is just oil that accumulated with the lines clogged and it will eventually burn off and be gone.

 

Tscompusa, have you ever tried using a check valve for the breather that goes to the intake (using turbo as pump)? I ask because I am getting the cracka vents and on their instructions they say to put one there as to only permit vapors being sucked by the turbo but no air getting inside when the engine is in vacuum. I have read many posts about how the breather and PCV systems are supposed to work, but still don´t fully understand if the breather side (by the turbo) is supposed to flow both ways depending when on vacuum/boost, and if that is the case then installing any check valve there would disrrupt the system? No more fresh air going in, but more vacuum in crankcase when not in boost?

Sorry if what I ask is obvious to some of you.

Umm...that is interesting...thanks for posting it...

 

I am glad you did it that way, this is essentially How I did my set up that is illustrated in this thread. with the one exception of running it back to the intake tube. I hope everything works out for you.

 

mine smokes a lot when cold, i think its normal.. when we first start up our rings are not gonna seal as good as older motors, we have new motors. so it takes alittle bit for the motor to even be operational properly. if i tried to fire my car up and drive off it would just stall.

you drove the car a good 10-15minutes and then let it idle and it still smoked? if so then id be concerned. once i drive mine the smoke is gone, but initial startup = lots of smoke when 15-30F.

You should try putting amsoil 20w50 premium synthetic in your car and seeing if you experience the same amount of blowby, i am almost 80% positive the amsoil oil helps seal the rings better then this brad penn. id be interested to see if its true.

I ran 42psi on my old setup on factory crankcase setup and never recall having pushed oil up the oil return line like im doing now. was running amsoil 20w50 premium full synthetic. id be curious to see if it really eliminates a lot of the blowby.

i heard others say it helped also. i dont know about you, but i dont really wanna put a full synthetic in my motor just yet, and you may feel the same way. I feel once i put a full synthetic in there we jeopardize a lot of potential ring sealing.

I think your cars fine btw, its probably just burning off excess like you said.

 

Be careful, mostly all the kracka krankvents are defective, so whoever you buy from tell them to test first before shipping. kracka is in the process of getting new shipments in so once they come in then they will be good to go. You can PM him on the forum.

No i will not run a krank vent or any form of check valve from the valve cover to can to air intake. im sure it assists in vacuum, but im not doing it.

 

ya it should be fine. Brian @ FP specifically told me to use the turbo as a vacuum pump and to run closed can with it going back to air intake.

I think it will work fine, because with no catch can there was no oil in the intake tract so it should be ok as long as the fitting is inside the baffling, which it is. will report back once i test it.

 

saikou michi catch can i have has the same elements inside, so no different then what i have. the research ive done there are only two extremely good catch cans that function perfect on the market..

1. http://www.saikoumichi.com/
2. http://www.jcsautomation.com/catch_cans.asp

there are more out there, but they are custom in house made.

 

The white smoke is gone. Now every now and then under normal driving conditions it is burning a little oil off. It is slowly going down over time, but still. I am not sure. The white smoke is gone, and now I am certain it is just due to cold weather. The blue smoke I am worried about, compression test was alright, I just think that with those lines clogged some oil found its way into the combustion chamber or even through to the exhaust and is slowly burning off.

If compression had been low I would be worried, but for now worst case is a valve seal or some other small seal. Thoughts?

 

If your catchcans are full the car will smoke a LOT! Make sure to drain your cans. I had one fill up one me and the car smoked like a blown turbo car. Drained the CC and it went away instantly.

 

True, Mine did exactly this when the lines froze up, but since my re-routing them and shortening the lines the problem went away. The first drive after fixing the lines it was burning a little bit of oil going into boost. I think it was just burning some oil that found its way up into the head/valve cover area when the can was clogged.

I drove pretty aggressively on the way into work today and didn't see a hint of blue smoke so I am guessing the problem is resolved, just a little worrisome..

 

took car out just now and i noticeably gained HP from the crankcase ventilation system i added. car will spin 2nd gear from a 45-50mph roll and spin pretty aggressively the car gets sideways and when i let off it nudges back in place, so its really getting loose. gotta be decent torque to do this with 18inch wheels and 255 wide tires.

the whole spinning thing isnt what i had in mind, hopefully its just the roads but i feel about a 10-15whp difference at least. i didnt get a chance to log any pulls but i will once i feel better.

its gotta be around 615whp i think.... no clue what torque. still at 31psi.

things i noticed:

1. little bit more power

2. car feels more alive, like its not sufficating.. inbetween shifts it wants to lunge forward..
and gears feel like the car wants to inch ahead at all times.

3. no more smoke on throttle lift at all, and no more oil coming out of the vband on turbo

when I drained the intake manifold side catch can clear / cloudy liquid came out.. i sniffed it, it smelled like water and e85 mixed.. now i feel like im going to puke.. i dont know if its from sniffing that stuff or because im still sick, but it was a horrible smell.

I highly recommend anyone to do this mod.. i noticed a lot of things different in my car.. it just feels like it wants to go, rather before it felt like something was holding it back alittle compared to now, plus the oil coming out of the turbo chra was super dangerous.

also nothing came out of the catch can valve cover to air intake side.

 

Nice review Tom...when was the last time u drove the car? You sure the increase in power wasn't just from it being colder out??

 

drove it in 25F before, its 36F here now. it always spun, but it just slams limiter no matter what road its on now in 2nd at any mph.. cars noticeably more jumpier and free in general. it feels like i removed a massive restriction from it.

it feels very very different.. i cant put it in words any other way. power wise theres a mild increase in power from my butt dyno.. im usually right when it comes to that.

it feels similar to when you drive with your downpipe disconnected vs having it on.. the car just feels more free reving and more happy.. i must have a **** tons of crankcase blowby because this mod really changed the car a lot.
