I decided to stretch phase 1 of testing to 1900 miles, since that will be my miles to Texas this fall. So I drained the tanks on Thursday, April 14, and now it's separated pretty well. I got just under 1/2 cup in the intake-side tank, but only trace amount in the turbo-side tank. Gasoline on top, oil in the middle, water on the bottom? Seems like more gasoline than I expected. Phase 2 has begun!



In the factory-equipped design, the turbo only had to depressurize about 10" of hose. In phase 1 design, the turbo had to depressurize 6 feet of hose, the catch can, another foot and a half of hose, and the 3-cup collection tank. I think the collection tank may have been counter-productive.

In phases 2 and 3, I don't think it will cause a problem. With both vacuum sources pulling alternately on one vapor draw point, the vapor should pretty much keep moving along towards the catch can.

I also discovered that the aluminum fitting I used for the new manifold port has, indeed, been leaking.



The brass fitting I had originally planned to use seems to fit in the tapped hole a little better. Time will tell.

 

Man buddy, that's a lot of gas! Especially considering it's only entered into the combustion chamber. There must be considerable blow by for that much to end up in your crankcase. Eventually working it's way to your can.

I'm almost finished here in Canada, then I'm headed home and back to the garage to finish everything I had started. Catch cans coming soon!

 

Well, it could be that it is still separating, and the top layer is still a gas/oil blend. I'll keep checking it. It's in a mason jar with the lid on tight.

 

Better watch, now a Mason jar in a hot rod SS , could be mistook for 'shine!

 

We can tell RJ is a scientist type! Seems like he's always separating fluids in a mason jar. But, as I've said before. I'll be relying on his research to perfect my system.

Thanks again blue, you're always good for a laugh!

 

So the other day I was backing into my garage, I see a car pull into the driveway and someone gets out and walks towards me. I thought I had the only SS in the area.

The man introduces himself as Randy and says he has a 2009 HHR SS. I said "What? MY name is Randy, and I have a 2009 HHR SS!!"

Will the real Randy with a 2009 HHR SS please stand up!



Turns out we work at the same power plant, too! His SS is red, mine is silver. Randy is putting a LDK in like some of you are, and wants to install a catch can. He asked me for a drawing for a 1-can system, so I've made a drawing of what my phase 3 will look like, since we believe drawing vapor from the intake manifold is probably at least as good as(most likely better than) port 2.



I had a hard time with paint, it kept giving me an image that was too small to see, I finally got this, but then cropped off the tee into the brake booster line. AAARGH!!

Again, please excuse the crudity of this model, I didn't have time to make it to scale!

 

EVIDENCE!! What's in that Mason jar, is evidence!!

 

How can you draw from the intake manifold? Isn't that a vacuum?
I admit I don't really get the whole thing, something just doesn't look right.

Do you really want un filtered air going into the crankcase?

 

It's the part of the intake manifold that used to house the PCV valve. We've plugged the hole that leads to the vacuum area of the manifold, so now this part is only open to the crankcase side. Then we drilled and tapped this part of the manifold to draw vapor from the crankcase.

The air inlet hose connects the airbox to the turbo, so the fresh air to the crankcase is filtered(and metered).

 

Randy
Are you using another PCV as the check valve to the turbo?
