Oil catch can?

[Elite Engineering]

Man, after reading everything here, I'll most likely be getting the Elite Engineering Standard Can. I had to order my truck, so I'll be able to install this with next to no miles.

 

So it sounds like even in the winter time, these cans should be ok to run, and there are no negatives if for some reason the fluid in the can froze at the bottom?

 

My other question is, I think that I read the Elite Eng. Can uses a steel wool media... does this ever need to be replaced?

 

No. If you like, you can remove it and wash if ever needed, but it should last a lifetime. One of the benefits of an Elite Engineering Catch Can is that you can take it apart and get inside to clean if you want.

Ok great, thanks!

Freezing won't hurt any of them out there - unless the thing is full to the brim with water. In that case your going to have more problems than a busted can ...

I got a little more than 1/2 oz after 285 miles. Looks like chocolate milk!

Yep - just like mine. I'm curious if the condensation will decrease once the weather warms up the next couple months. It's a byproduct of combustion, so maybe not. We'll see ...

 

 

After a 40 mile drive yesterday I popped the hood just to check it (haven't emptied it for over a week), and out of curiousity I touched both hoses to see how warm or cold they were. The hose from the PVC was warm, as I expected .. but the hose to the intake was ice cold - even up close to the intake cover. That means my location up front there is cooling it off real good. Should keep moisture out of the engine at least.

It should around the end of May I see mine change to a black color with no more water

I read in another thread somewhere that these Catch Cans could possibly introduce some type of Suction Noise - has anyone experienced this? If so, just how loud is it...?

Not a peep out of mine, Nick.

 

 

Good to know Ryan - thanks! I suspected the level would cut down a bit. I get crazy condensation in there when I take short trips -can't even see through the glass. It's like the windshield in a rainstorm without the wipers on.

[wurgs]

No change in the sound of mine either.

[Bonker]

No change in sound on mines.

...to change the subject slightly...

 

Anyone notice that the two rocker cover vent tubes, going to the intake duct, are not valved (one way) for flow? That is; flow from the crankcase/rocker cover can flow in the direction of the intake duct. I noted oil up in those two tubes and some film in my intake duct. Not much, but it's there.

 

My assumption is that the system is designed to draw in from the PCV into the manifold. The pressure is lower inside the manifold than in the intake duct. That should keep the crankcase blowby flowing in through the PCV route...and into your cans.

 

Just more stuff to think about....

No vents in my valve covers. Must only be on the new ones. The PCV is the check valve on mine.

I'm not sure I understand what you're saying. The flow from these two tubes is supposed to go into your air box and through the intake tube to the throttle body. Valves aren't necessary either because backflow only occurs on turbocharged engines, not our stock engines. That's why the one-way valve on catch cans is necessary in turbo charged setups to keep back pressure from blowing out the seals in your crank case but we don't need those check valves on our stock engines. I did notice some oil on these two tubes when I removed my airbox but the inside of the airbox and the throttle body were both clean as a whistle so the oil seems to be coalescing at the snap lock fitting of these tubes. I may eventually spring for a clean side separator but we'll see.

Elite Engineering offers a clean side oil separator to trap the oil before it makes it to the intake air box.

First they connect the 2 valve cover nipples together to allow left and right banks to breath. Then they

replace the oil fill cap with the separator which has a tube running to the driver side air box nipple.

The other airbox nipple (passenger side) is capped off.

 

The purpose is that at full throttle, air is drawn from the valve covers into the air box. The separator has

the steel wool mesh in it to keep the oil from making it to the intake air box. The oil in the separator is then

drawn back into the valve cover by engine vacuum under normal throttle load.

 

I've got this setup on my 6.2L along with the Elite catch can.

 

I had previously only seen oil near the bottom of the original breather tubes. My understanding

is that drawing oil into the intake airbox only happens during wide open throttle conditions. Since my

truck only has 320 miles on it, it has never truly seen WOT yet.

^ So this essentially only helps for WOT scenarios? Are they fairly simple to install?
