I just ordered this catch can because I'm trying to eliminate oil consumption as much as i can. I see what looks to be a one way valve withthe kit. Were does that go and flows in what direction?

the one way valve orients bottom side to rear valve cover or source of dirty air to top of one way valve which leads to oil catch can dirty air input

Yea man, how come you can't cap them off?
I was installing the catch can and noticed one valve cover vents too the manifold then the front valve cover vents too right before the throttle body... Why is this? I assumed i need to route both too the catch can correct? Because that's what I'm going to do is T them together, if that's cool?

No.  U only need to use the one from the rear valve cover. The one that goes to the center of the intake manifold.

Alright man thanks. I just don't understand why they routed the front cover vent up before the throttle blade n why not run it through the catch can too.

You should read up on how PCV systems work. The rear cover PCV pulls a vacuum since the intake manifold has a vacuum. Since the front PCV is before the rear, it sucks in fresh air from the intake plumbing. It's just one big system, pulling air in from the first PCV hose and pushing air into the intake manifold with the second PCV hose. If you T'd them together it would basically negate your PCV system and drastically reduce your engine's life.

Your PCV system works like so....The engines crankcase uses the front valve cover as the source of fresh air that passes through the crankcase and up to the rear  valve cover to let PCV gases escape and be sucked into the intake manifold via engine vacum.

I have a stupid, noob question on this:


I just installed a catch can, which is recovering about a shot-glass worth of oil every two weeks.

Since this is just oil sucked through a rube, is there any reason why I can't just poor it back into the oil fill?

I can't think of any reason why not, but I wanted some opinions!

This thread inspired me to order the catch can, which I'll put on when I finally get around to putting the LS1 intake in before it sits in my garage for another season.  Anyway, I'm curious too why not to just pour the oil back into the crank case.

I would assume u could pour it back in no problem.  Now personally I wouldn't but that's cause I modded mine a little. But you should be safe to.  And for some reason yall seem to burn way more than me...my can only catches a few drops every 3k miles when I change it and all in all I have barely any oil loss at all

O and by modded I mean I stuffed it full of steel wool (the scrubbers u can buy at Walmart) and also ran plastic tubing from the in line to the bottom of the can.  And sealed the can myself with rtv

Mine has steel wool in the top part so the oil has to go through it.

Wow, good article.  Thanks for posting.  Explains why the Ebay catch cans are so much cheaper than most.

So, based on the article, it's probably not a good idea to recycle the oil from the catch can, both due to filter media and possible water being deposited in the crank case.
