I believe the new system just hasn't had the time or the temperature to really show how it working or not.
The tubing is 3/8 ID and the fittings have 1/4 ID passages and I did disconnect them to check for any plug of any kind, thinking the same thing.
Now, if the can needs to be vacuumed of atmosphere to allow oily vapour from the inside of the valve cover to be sucked out, would the negative pressure from the throttle body be enough to suck that vapour up the inlet, and into the catch can?
I think if the can was mounted, below the level of the valve cover outlet, then, yes it would.
I don't have much room to lower the mount on the air cleaner box and if I mount it on the rad cradle then the tank is in the way of the oil filter .

 

Manifold vacuum, at idle, is certainly enough to evacuate the crankcase, even to depressurize the can, no problem at all, should be nearly instantaneous. Cruising on the freeway, however, you'll have much less vacuum, but still should be no problem.

And as far as trapping contaminants, RF2 is right, lower is better, but you also have a valid concern about freezing. But if you empty the can regularly, it shouldn't expand enough to damage the can. I would think it could even get about half full without damage. It should take months to get half full. And you've got a level indicator.

But you're basically the same now, as the anti-Newton design(s), so I expected similar results. Sounds like you did, too. The dirty side tube should be at least a little dirty, even if it's only right near the valve cover.

That triple clamp at the valve cover, is that just a reducer?

 

Yeah it's a clear tube to the reducer then the blue hose.

 

Oldblue, how many miles are on your wagon??

 

226,000 miles

 

If you are concerned about the can freezing located behind the front bumper, just put two teaspoons of winter windshield wash in the can. This will keep it from freezing. It will freeze under the hood when the engine is off just like your windshield washer tank would with out it.. Vapors from the fluid will not hurt your engine. Some people use windshield fluid instead of methanol for their water injection systems. It looks like you have the same can that I have.

 

Great suggestion, thanks

Today I went out and checked for any vacuum at the fitting at the white teflon tape at the elbow by my throttle body, there isn't any.

 

Let me put on my non-turbo, N/A thinking cap.
Full vacuum can only be captured "after" a TB or carb.
(see where I'm going with this )

Anyhow. Just pondering your vacuum issue as I wait for some paint to dry on a door hinge. (yeah, replacing hinge pin and bushing on the old Dodge )

 

I think mine must have been in that box that went to the thrift store.

OB, I'm tapped into the brake booster line, right where it enters the intake manifold.

 

That might work for y'all 's SS but I'm not teeing into that line.
I had a nap, woke up all startled and thought, hey ( just like FMG says) there is no vacuum on the air cleaner side of the throttle plate, at idle! Maybe I should just come and watch that paint dry for you George, now during throttle while driving yes there is some vacuum at the fitting but not much. So , back to allowing time and driving the trip to Hamilton on Feb 28 to see if anything gets up the dirty line and into the separator tank.
