Hey,

Few questions ive found everything about installing them. I will be installing my catch can in the back of my bock to replace the old pvc system. Just wondering if because i have a sealed catch can will that make a difference (Mine looks very similar to http://www.c-speedracing.com/h...4.jpg)? Most the ones i see are vented with filters on them. Also since my catch can is not baffled i have read to put steel wool in it. Do you just cram the canister full with stainless steel? Does the stainless steel ever have to be replaced as the opening in my catch can isnt very big so it would be a pain to replace.


Thanks guys

 

As long as you are running the lines from your block into the can and then up to the manifold you do not use a breather on the can. As for the steel wool you don't need to cram loads of it in there, there just has to be enough to keep the oil from sloshing up into the intake line. Put enough in there so that it is about 1/2" to an 1" from the inlet and outlet ports of the can. That way you won't have any chance of the oil sneaking across the steel wool and into the outlet port.

 

Don't use steel wool. Get something made of plastic that won't break down in oil like one of those bath scrubies or something like that or don't use any kind of baffling at all and vent to atmosphere.

 

Vent to atmosphere won't work with the (vacuum assist) PCV catch can setup that he is talking about doing.

As for the steel wool I meant to say stainless steel scrub pad.... not the really fine stuff either. Petrolium safe Plastic scrubs will work just as good, I didn't find it as custom fit friendly as the steel scrubs.

These are what you are looking for. You can pull them apart and make them as dense as you need them to be.

From what I have hread i was going to run Both into the back of the block and put a vacume cap on the intake manifold line? The Valve cover is still vented to the atosphere.

Thanks

How does that work?

The pressure is all going to go out the vent with the least resistance. ie the hole in your valve cover. Nothing is even going to go through your catch can lines if you do it that way. You need the vacuum or Plug both the manifold and the valve cover and run a vented can if you plan on running that type of system.

My setup is like this.

I put a filter breather on the fresh air intake port on the valve cover.
Ran a line from where the PCV valve was on the valve cover to the intake port of my catch can.
Ran a line from the output port of the catch can to the intake manifold PCV vacuum inlet. Positive vacuum breather system still no oil or solid crap getting into my intake. I may lose .0025hp due to the temp raise...

All is gold fresh air goes in to the engine and crank case gasses without any oil get sucked back into the combustion chamber as they are supposed to.


My 0.02 worth about atmosphere dumping pcv systems.
All I have to say about venting to the atmosphere is don't complain or blame anyone but yourself when you are lying in a hospital bed with cancer. Ever wonder why some peoples cars stink of gas and burnt oil when you go near them. A good guess would be an atmosphere vented crank case or poorly maintained PCV system. Those fumes are highly carcinogenic. I guess it works great for a turbo or race engine but on a DD totally useless.

bah! who cares about the environment?!?!?! we are involved in a very environtmentally unfriendly hobby, a vented catch can is not as bad as almost all the other things we do to our cars.

 

So I will remove the old PVC system.. bock off the old exit. Install one of the h22a breather nipples and direct it to the catch can. Then the second one will go from the catch can to the intake manifold where the old pvc system was leading to.

Is this correct then?

 

Well i some extra honda parts that i didnt use...ohwell. Took out the old tube that goes from the pcv valve to the intake manifold and routed it from the pcv valve to the catch can and back to the intake manifold.

 

anyone know if the Cusco can is baffeld or needs to be baffeld? I've heard a couple of things like "it's big enough it doesn't need to be baffeld" and "it needs a baffel"...so I'm guessing it doesn't have one but, anyone know if it needs to be done because of it's size?
