All oil catch cans have one purpose. To catch oil. Doesn't really matter what brand it is. Just like if you wanna pay for a brand name intake or a home depot special, it just only does one thing with the exception of aesthetic purposes. People just don't like the idea of having oil inside the intake or don't want to mess with a filter breather because oil will be splattered everywhere on the engine bay.

So far I only know one oil catch can that can also "act" like a krankvent. Road Race Engineering Oil Catch Can. Look it up.

Go buy a fuel filter for 3$ and make your own, takes all of 2 minutes.

Completely wrong. Please don't fill the forums with mis-information like this.

Not the best solution, for a few reasons.

OP - I suggest you do some research. Here's some reading to get you started:

So your saying

Install a catch can for your DSM (2G)

Doesn't work? I have been using it for about 2 weeks now and if its a problem I would like to know.

I'm saying that paper fuel filters will usually pack off with oil and cease to do anything at all in a very short time. If they do actually remove oil, they probably have too high of a pressure drop and most likely aren't doing much for the crankcase pressure.

They aren't designed for oil vapor and blow-by removal, and using them for that purpose isn't the best solution.

So the best option is to drop 140+$ on a catch can system? That's dissapointing , I suppose my new IC pipe order can wait.

The best option is to use a catch can and PCV system that is properly designed, regardless of how much it costs. Catch cans sell for a wide range of prices; some of the expensive ones do nothing but look nice, some of the cheaper ones don't have the anodized finishes and "aircraft machining" but work very well. (As far as my cans go, $140 is towards the upper end of the price range for a single can; I have others that cost less than half that, but they all use the same inlet filter design).

The bottom line is that you should be able to come up with good crankcase ventilation and a clean intake for much less than $140, unless you are pushing a lot of power or need extra capacity for race regulations.

If you hook up a $3 fuel filter or a Home Depot air compressor filter to your crankcase evac system...well, you get what you pay for. Been there, done that.

I made my catch can for free out of stuff laying around my shop, and it's the ugliest thing under my hood, but it's not restrictive, and it's been keeping my turbo inlet bone dry for two summers now.

It has no breathers on it, and it's fully recirculated back into my turbo inlet. I would tell you how I did it, but then I would have to kill all of you.
