Need Some Knowledge

[satanic]

I remember seeing a thread about this a while ago, but my search turned up fruitless please don't kick me for posting this up again. Also, if there is anything here I have said that is wrong or dumb, please correct me by all means.

Just got an Oil Catch Can which appears to be hollow = "unbaffled"? Reading up on it, this means that the can is pretty much pointless ~ not good!

Someone said that steel wool in a stocking stuffed inside will solve this problem. Is this what baffling is? If so, what type of steel wool - what type of stocking And is it literally as easy as stuffing it into the can somehow?

Thanks all...

PS: Some of the cans I have seen have a filter on the top of it... does this filter have a purpose? I might think about modifying the can to fit a small K&N in there as well (good/bad, you tell me)

You need to make a divider which seperates the inside of the can into 2 halves, one half for each hose. This is best made from thin alloy...

At the bottom of the divider you should drill some holes for the air to go though, note these holes should be at the bottom as it forces the air to go through the stocking which is the next bit.

Stuff some kitchen scoures (spelling, you know what I mean) into stockings, tie them off a put one in each side of the catch can. Dont use steel wool as it can rust!

The stocking should catch the oil but let the air through, so now you have an oil/air seperator

Oh yea, the filter on top is for external venting cans which are illegal due to emmisions laws.

Cheers for that... great help (especially about the filter)

However, what if the I can't make a divide? The access hole is literally like the size of a 10c piece

[GunMetalR33]

So its empty and you cant open it?

My Greedy one has alan keys to take the top off. Where are the locations of the hoses connected to the can? If they are at opposite sites to each other then I guess you could just shove the stocking in between them.

A pic of your catch can would help...

I'll post a photo up when I get home tonight... can't do it right now.

Yeah, the hose connectors are right opposite each other - the design is just like a Cusco can. Even if I can't make the divider inside the can as you suggested, you rekon it's a good idea to just stuff the can with kitchen scouers in stockings?

[GunMetalR33]

I would have to see the photos before I can say, but put it this way, unless your catch can is going to vent to the atmo then an empty can is pretty much doing nothing but look good.

Here you go matey... photos!

Mate, are you sure that you cant open it. I'm just asking becuase it looks to me like that bracket around the top might come off or something. If you cant open it and put a seperator in then I would get one of the readline filters to run off one of those outlets, note this is not legal though but it would stop oilly air going back into your intake...

Juts shoving the stockings in through the little hole wont work very well for two reasons:

1) The air is not moving through much of the filter because those outlets are very close together.

2) It would be an absolute biatch to get the filter out when it needs to be replaced.

[satanic]

Where can i get one of these readline filters o wise one

and by the outlet you mean the blue nozzles yeah?

[GunMetalR33]

yea put the filter on one of the blue nozzels. You should be able to get the little filters from places like autobarn etc etc. There is a really good thread on setting up catch cans by sydneykid on here somewhere, try to search for it as it will be a good guide for ya.

My catch can is set up to plumb back into the inlet which is the legal way but if you have a hose from the one of the blue nozzels then connect the little filter somewhere burried in the engine bay then you should be right

[satanic]

I'll need to T-piece the filter from the main line yes? That way the oil will still flow through the tube but have a filter for it to 'breathe' correct?

[GunMetalR33]

This is what you need to do:

See the hose comming from the cam cover to the can, yours should be the same. With the one comming from the can to the inlet, instead of running the hose to the inlet run it down into the engine bay so you cant see it then put the filter on the end of it.

[GunMetalR33]

Try to find SK's thread as there are many ways to set this up depending on how you us your car. eg, PVC valves block etc etc.

PVC would be a good place to start your search... OR is it PCV Sorry I am not sure...

Thanks guys... SK's setup looks to be quite complex Looks like I'm going to need quite a bit more parts (bungs etc.)

Bungs yes but not too many, I think only 1. I think you can use a ball baring to block the PCV valve...
