Here is a how to on building an oil separator (catch can) for $15.
Most units run anywhere from $30+ and just shoving a breather filter on will still allow oil to drip past.

You need a few things from home Depot

You will find these with the air compressor accessories. It is a water separator, and a couple fittins and some thread lock.


Here is a close up of the water separator.


You can discard the filter that comes in it.


Wrap the thread lock around the fitting. (Of course this is easier with two hands.)


It should look like this.


Once you are done, screw the fittings in to the separator. Your finished product will look like this.


It is now ready to be installed in the car.

I see someone stole this from the SRT4 boys ;)

Good job thou. Add some after picks once you see some oil in it.

Nope, I got the idea from Aaron who had it before the SRT4 was even out. :hmmm:

People have been doing this for years.:hmmm:

I am thinking I will mount it to the back fire wall. Not sure yet. You can make a bracket out of aluminum straping like I did. I just wraped it around the cantainer in a way that I can mount it then justslide it out to remve and empty.

There, he gives a much harder and not as prety looking DIY but the concept is still there.

You won't by any means need on that size but if for some odd reason you feel you need a bigger separator, then you can buy one for about $8 more sitting on the shelf next to these.

I did this on my T/A 4 years ago. I did it on my Tib after going autocrossing and blowing smoke after every hard corner.

When combustion occurs, there is some leakage past the rings and so down into the sump. This pressurises the sump a bit, with these gases making their way up to the top of the engine. The oil/air mist is drawn off from the rocker cover and directed into the intake, where it's sucked the engine and burnt.

stopping this oil going back into the intake has some benefits, especially if the engine is breathing a lot.

I can remember the first time I sucked oil out of the head and into the intake. It was on a Long sweeping 270 degree onramp from the Garden State parkway to Westbound Atlantic City Expressway.. The car was three days old and I thought for a moment I had really screwed something...

Nice Catchcan.. and it has the built in drainage at the bottom.. might want to make sure you put it in a spot where it can be easily emptied.

Thats not how you would drain it. That is an air valve like the ones found on a tire. Its purpose is for relieving air pressure before you remove it from an air compressor. You won't use it all for oil since no pressure will build up. To empty you simply unscrew the little container and dump it.

i understand the utility of the oil/air separator but
I've put a small breather on the valve cover

is it better ti put an oil/air separator and relink it to the intake?

A breather valve is not evironmentally sound because these gases are let out into the atmosphere, so yes, it is better.

Pretty easy to make. Now just having to wait for the engine to cool down. But I went to HOme Depot to get the catcher and tape. Its in the "tools" corral. Then at Lowes go to the "Tool World" and I found the gold thingies.. (blanking on the name). Now I just need to figure out how to mount it. Probably temp i'll zip tie it tightly to something.. or find me some aluminum (sp err probably). Good write up. This will stop my squeeking noise. The dealership will love this new mod.. (rolls eyes). I can just easily take it off though. So no biggie.
