DIY: make your own catch can for <$25

[jma_1000]

NO. You don't need this. It is something to kill time for cheap, obsessive, worry warts like me.

The theory is that you might fractionally extend the life of your turbo by keeping a tiny amount of oil, water, and fuel mix from making its way into your intake. You'll be fine with out doing this mod.

On the other hand if you believe that it does something significant, then YES, it will have the same benefits for someone w/ a stock WRX as it does for a modified one. So you should probably do it. Maybe.

Besides, if you don't do it and your turbo dies prematurely you will always wonder if it would have saved you.

Hope this helps, T.J.

+1, well said. exactly why i chose to do this.

Looks like the one I bought at Home Depot. Look near the air compressor parts.

Edit: He may have stuffed it w/ steel wool or something that the mist could stick to.

[jma_1000]

yep, got all the parts at home depot. i used a coarse steel wool, like T.J. said.

haha, i cant believe how NEW my engine bay looks! i definitely need to clean it.

sorry to bring this post back to life, but how did this air compressor catch can work out for you? can you see the oil build up in the bottom? thinking about doing this tomorrow.

I know it's been a while since this post was made, but I was wondering if anyone had any updated pics of the catch cans that people are making. I get the idea and am sure i can do it. I just prefer to see pics.

So I did my catch can, looks just like jma_1000 and was wondering if the arrow on the can matters which way it was pointing. On his its pointing towards the IC. Mines the same way. Anyone know if this matters thanks

I tried finding that husky filter BUT this was the smallest, most comparable one i could find:

Ok, so most of the links to pictures have gone dead but ive pretty much got it i think.


the filter at the 4 o-clock position is coming from the crank case and into the inlet hose on the last port before the turbo
the filter at the 9 o-clock position is coming from the hard PCV pipe across the inter cooler into the first port on the inlet hose.

my question is: I have been unable to locate the grey/white PCV valve w/ electronic connector and as i read, my understanding is that the 02, 03 models have the PCV valve w/ no electronic components attached to the intake manifold below the throttle body. the crank case vent is a oddly shaped 'T' fitting with one hose going to the PCV valve and the other going to the turbo inlet hose (the one ive added a filter to)

so for best results i should i splice in a fitting to the crank case vent---> to the filter----> to the PCV valve on the intake manifold?

or should i just plug the other side of the 'T' fitting going to the PVC valve on the intake manifold and splice in a new 'T' fitting on the filtered end of the already installed hose going to the turbo inlet---->back to the PCV valve?

both involve me taking the intercooler off, the Throttle body off and cutting the line going to the PCV valve. but is capping off one of that oddly shaped 'T' fittings ends going to screw something up? i mean in there a valve in there? why is is so oddly shaped?

oh god i am has a confuse

Looks like a snake found a home in your engine.
