Recommendations for a catch can

[NU13]

Ok boys and girls i'm looking for a recommendation for a functional LS1 oil catch can. I have read a lot of reviews that say the Elite catch can works well. But what about the likes of the Autotechica cans and other brands?
Cheers

How are you going to run it, vented?

Are there options? I take it the vented ones have the breather at the top of them?

Yes, some cans have a bung in the top to run vented. I ran a closed can in conjunction with the pcv system and while it did catch oil it didn't get it all. Finished changing it to a vented system last week.

Which vented system did you go for?

It doesn't bother me (coz mine vented as well), but
just to let you know, that vented systems are illegal.

But mine's vented through the air intake on one side of the rocker cover and a small vent filter on the other one.
I've had this system on for about 7 months and have NO sign of oil in the T/B or in the filter,
as there's no real suction to talk about on the intake side of things.
It just vents into the air intake and out through the filter.

So in reality, I could gut the innards of a PCV valve (to make it look more proper), put that on the end of the rocker cover
that connects to the air intake and it would "probably" pass.
It actually looks like, that air is drawn through the small filter on one rocker cover,
through the crank case and out through the other rocker cover and into the air intake.
But it doesn't actually suck (it just looks like it does), it vents.

I'll put up a picture soon, of the set up I have.

I take it you mean illegal in Australia? So both of you guys are recommending vented units then?

I modified the closed can. Drilled and tapped a 3/4 bsp thread into the top and fitted a nipple to take the filter. Running 5/8 (16mm) hose from each rocker cover to the can. Works well.

Yes, closed system didn't work for me.

Yeah....Illegal in Australia. Don't know the legalities of a vented system in NZ.

Personally, I'd run vented,
I realise the engine is tuned to accept crank case air (vacuum) into the inlet manifold,
but a vented system eliminates that, gives you cleaner air into the cylinders and imo, gives better vacuum in the intake manifold.

But that's just me....
