Reducing oil consumption.

[dirtysouth_msp]

Except the KV is basically a check valve and breather filter minus the catch can. Also, there are cheaper catch cans than those I mentioned. $40-60 if you look around just not as fancy.

Yeah the more I looked at it, I realized that they are just fancy and extremely heavy duty check valves and that you could make a basic setup like this for cheap with parts from autozone, etc. Although, I've see blown out check valves on turbo cars before, so I guess these are probably better in that they are so heavy duty. The price is high IMHO, but oh well.

Oh yeah, apparently I gained so much HP from installing the KVs that I busted my differential this morning, (attn) lol jk. But it did give out this morning...

Been there, done that, got the t-shirt. Didn't solve s*** except getting my engine bay filled with oil from the catch can lines everyday. :'(

I'd like to see how you exactly hooked the lines from the pics you posted. I see 3 lines going to the can. On mine I have only 2.

Don't you have a 1-2 yr old built motor? You shouldn't be having oil consumption problems already. Unless it's your valve seals. Did you replace those when you did your motor?

Especially with as low millage as he has.

This is the best shot of the old setup I have got.

Yea, i've got a MAM block with about 8000 miles on it. We replaced the valve seals and every other seal on the engine when it was put back together. The car chucked out oil like it was its job into the catch can from day one. But it ran great.

Old Setup was:
-Millenia PCV > Catch Can (Other Manifold Vac Ports Closed Off)
-Valve Cover > Catch Can
-Catch Can > Intake Breather

This was identical to the setup the shop had run on every other boosted Honda they had ever built with no problems. The idea being that the engine wouldn't be ingesting its own oil back into the intake manifold, thus making more power.

Once put back to stock, the car started detonating a bit on its tune due to the oil being ingested back into the intake manifold.

I installed the KV's and ditched the Catch Can and now i'm looking to retune the car now that it shouldn't be ingesting its oil.

I'm open to suggestions, not trying to start a war here. A little debate every now and then is a good thing!

I'm thinkin about ditching the millenia PCV since it seems largely worthless.. did it actually reduce blowby at all?

But what will you plug that hole in the valve cover with?

 

[Kansei]

with a stock pcv.. sorry forgot to clarify that

If I decide to ditch the PCV system I'll probably use a hollowed-out stock pcv valve or something... and of course plug the nipples on the intake manifold.

Just wanted to update you all on my experiences. I now have proof (at least to me) these are preventing the engine from eating oil. I took the car out last night and beat on it (i mean really beat on it) for a good hour. Redlining it, hard boost accels, decels, the whole lot. I put her back to sleep and this morning came out side to look at the rear bumper.

NOT ONE SPEC OF OIL. I mean this is huge for me being the detail freak I am. I would spend hours cleaning every inch of the car only to drive it 3 miles to the car show ever week and have to clean the rear trunk, bumper and wing of the little black specks of oil that the car would spew out of the exhaust constantly.

If the krank vents did nothing more than prevent this it was worth 10x's the price to me. But the more important thing is that it proves that oil is no longer being used and spit out the exhaust from the PCV allowing bleeding on-boost oil into the engine.

I'm a believer. I will be putting these things on any and every car I own. Period.

That's great to hear, I just received mine today.

That's awesome! thanks for the update.

I'm thinking of taking the one off of the side. Seems a little hotter under the hood...

I now know where my extra heat was coming from: Click Me To Find Out!!

Dude, that sucks man. Hopefully you can drill it out and re-tap it or something.

Glad it wasn't KV related.

 

[Tzar177]

daedalus: how do you have your pcv side hooked up?

Got it out, and put in a new stud WITHOUT taking off the manifold. (yippy)

PCV > KV > Intake Manifold Port 1.


My other intake manifold port is blocked off for all intents and purposes.

 

[MSP 2731]

Here is a question, do we not need the vacuum line going to two intake mani ports from the pcv valve? Or is daedalus just special?

 

[daedalus]

Technically mine isn't closed off, but it is connected to an electronic valve that opens up when I turn on the A/C to create a VAC leak that idles up the car. (Because the Microtech disables the stock ecu control of idling up the car with additional load).

But, even when we were on the stock ecu, we closed off one intake manifold port anyway. There is no reason, or additional benefit of having two.

Sub...

Reading stuff like this makes me worried.

*Runs out to check oil level after work!*

Well this is helpful to know. I have been looking for a vac source off of the intake mani that is closer to the wastegate then the one I have it running from now. I wonder why they had it connected to two ports?

Well, since the ports are basically in 2 different runners, I'd say they did it that way so that combustion of vapors is divided between 2 cylinders rather than going straight into 1 cylinder. Probably won't make too much of a difference, but the logic is probably something along those lines.
