Oil Catch Cans: Who needs them and which one to get?

From Perrin's Website:

Anyone have any recommendations on particular brands?

 

home depo is my preferred choice
concealed and dual can option

dualCANS

 

:werd: and inexpensive also

 

The dynasty auto ones on ebay are really cheap too...nice solid machined aluminum and it was like $35 shipped I think.

 

I think the only one that really works is the Crawford air/oil seperator.
But it's $$$$.

 

in theory even a coke can would work, I am running a Perrin unit

 

Ming: That looks pretty good.

Anyone else running dual cans?

 

And the last time I re-adjusted one of my t-bolt clamps, I noticed some residue hnoes:

 

Good info!

 

There are a few more expensive ones that drain the collected blow-by oil back to the pan (I think the Crawford one mentioned above is one). That would be the one that I would get simply because it would not need to be drained.

 

Would there be any reason you would want to know exactly how much blow by oil exists? Maybe to gauge the condition of the rings?

The Perrin style units with the sight tube can allow you to monitor that whereas the recirculating separators will simply take the oil back to the pan.

 

I'm currently running a redbull can

 

If I remember correctly, it's sugar free too :rofl:

 

I asked SS and he recommended only one can. There is a lot of varying opinions on this on Nastycock. I am getting one because it was gunked up blowby that stopped up my PCV and remember that made the car puke oil only I was lucky.

Ming I love how clean your kit looks. How often do you have to drain yours? People like Milo and myself that run high hp engines on bigger turbos would most likely have more blowby.

 

I would think that if the blow-by condition was that bad, there would be other obvious symptoms such as excessive smoke from the exhuast or lack of power.

 

I just a couple of these cans (http://cgi.ebay.com/Oil-Catch-Can-R...6QQihZ017QQcategoryZ72205QQrdZ1QQcmdZViewItem) and then this plumbing kit (http://www.iwsti.com/forums/showthread.php?t=68600)
