What is this?

I was checking the oil yesterday on my new 300 and I noticed what looks like a 90 degree vacuum hose connector that has a hose coming off of it with one end just open to the air. It's right beside the oil filter. I tried to follow the hose but it disappears up under the engine cover and I didn't feel like trying to pull that off.

Any of you out there with Pentastar engines in your Chrysler/Dodge/Jeep have this? Is this normal? Is this just a vent of some kind, maybe for the PCV system, or do I have a vacuum hose missing? I guess I'll wind up driving back over to the dealership and find out.

Maybe a crank case vent. Isn't the Pentastar a high revving engine?

My guess is it vents the crankcase to keep the oil splashing properly when under WOT.

Again, I'm completely unsure and have no idea.

If it's a vent, it's exhaust only. Where are they installing the batteries on these?

Any other intake is going to pull filtered air from the airbox.

No PCV system is going to open ventilate in any event.

Wouldn't surprise me if it's a fitting to nowhere for uninstalled optional equipment. Or a test fitting. Or a flub that needs fixing.

But your last sentence will give you the answer.

The Pentastar does not have EGR.

I remember my dad's old 75 Volvo 245DL. That thing had a simple PCV system that consisted of a rubber hose attached to the oil cap and was directed downwards to the ground. That's it!

Boy how things have changed!

Closed crankcase ventilation systems were one of the first "emission" controls on US cars. The earliest ones didn't even filter the intake side.

Before that, like that Volvo, they just exhausted the fumes out the bottom of the engine compartment.

I doubt very seriously if a 75 Volvo had open crankcase ventilation. No way it could meet emissions standards.
 
I'll give him the benefit, as it may have been a Canadian/non-US vehicle.

But no way that would be allowed in the US by 1970.

He just got the car. And then it got severely hail damaged. Cut him a break.

Paper? Our last three vehicles, the factory service materials have been paperless. The last two I have to run a virtual OS to even use. It's a PITA. Miss those big books.

Yes, that would have been definitely possible up here. For joint U.S./Canada vehicles, the emissions systems were more similar. For something that might have been European and only brought to Canada at the time, anything would have been possible.

We've piggybacked on your guys' emissions standards for a very long time.

Factories don't use those ends on any outlet venting. things are contained.


Similar fittings may be used for ventilating differentials or transmissions, and even vacuum operated components.

Ha! your in Regina! I grew up there. And yes, it was a joint venture car as it was built in a NJ plant.
Very robust little FI'd B20 esp in the prairie winters.
