Joe I really hate to have to go against anything you have to say since you are always right! And truely are a legend in your own mind. I would say you are correct 95% to 98%. And you are always against someone post info that is misleading or wrong. So, I hate to be the one to tell you I think you are wrong on this one. "Its not a filter, just a cooling area" Now the way I see it the doghouse (OEM doghouse employs a woven stainless steel mesh) with what we can call a filter or better decribed as a collection area for oil vapors is a affected very little by cooling the vapors. But it is effective way to trap or collect the vapors on the media in the doghouse. So with more media surface area more vapors get trapped but when you increase the media area you are resisting the flow which will cause a positive crank case pressure. The same thing can happen with a dirty doghouse.

By the way what the heck is K.I.S.S. ??

Now for facts if you vent your ccv to atmosphere you are relying on postive crank case pressure to evacuate the crank case. And with a ccv going to intake or exhaust is using a vacuum/ evacuate the crank case with negative crank case pressure. Yes both ways will work but I think it is up to each person to which is the best way to do the job.

The negative side affects of venting your ccv to atmosphere you are relying on postive crank case pressure to evacuate the crank case. Is if you have too much postive crank case pressure bad things can happen and it robs hp.

The negative side affects of venting to intake or exhaust with negative crank case pressure. Is too much vacuum or negative crank case pressure will suck oil and vapors out of the engine. Which is bad too. But it will not rob hp.

So before any of you believe anything Joe or I say please do your research. Because there actually some really go write up's out there and Timmy posted some really good ones in this tread.

 

Hey Ed, K.I.S.S means keep it simple stupid

 

If 17 gauges is Joe keeping it simple, I'd hate to see him go overboard lol

 

(18) once he adds the doghouse gauge.

I've always wanted as many gauges as Joe, but my engines kept blowing up... One of these days! Well, maybe not the doghouse...

 

I can't see how having a positive crankcase pressure would rob horsepower. For every piston coming down, there's another one going up, so aside from pulsations caused by the inertia of the air, I would think the pressure would remain pretty static, at whatever value.

I could be wrong though.

 

To be honest I don't know exactly how positive crankcase pressure truely affect hp but this a fact that has been proven on a dyno. This not just internet hear say. You do the reseach and you will see that for whatever the reason positive or should I say a certain amount of postive crankcase pressure robs an engine of hp. At what point does it rob hp you would have to ask the guys that have done the dyno testing. I am not one to believe everything I read but I do believe that back to back dyno testing as to be proof.

 

Positive cc pressure also causes oil leaking past the seals. Even if it doesn't effect hp, which I'm not qualified to say either way, you shouldn't want oil leaking at the turbo seal. Smokes like a chimney out the exhaust. (figured that out Tuesday).

 

Okay, if the pressure were high enough maybe, but it can't be that high bleeding to the atmosphere, unless there is a blockage somewhere. And how much horsepower is effected?
Maybe a gauge would be a good idea? (sorry, had to)

 

". . . . . isnt the stock configuration setup to have pressure against the ccv? the little tube is facing towards the front of the air intake so the incoming air would have to pressurize it a little wouldnt it?"

No, the turbo is pulling, creating negative pressure at the CCV. It's sucking stuff out, even if it don't seam like it.

 

When I swapped my stock inter cooler and pipes, boots, clamps. The stock cooler was dripping with oil in it. That's all I needed to see to vent mine to atmosphere. But being in Australia and there not being many F trucks around and it gets people looking at it. I get funny looks sometimes when a feint cloud of smoke comes out from under the tub. I would like to plumb to the exhaust to stop that. Doesn't bother me but one day I can see a letter in the mail from the EPA, already had one when someone complained that (my exhausts were smoking). Haha.
