First I will explain what a catch can does and why the ss/sc guys should have one.

When the s/c is not creating boost, it is creating a vacuum. When the s/c is under vacuum, it is sucking dirty oily air into the s/c. This catch can stops that. Any water or oil that is in the air will get filtered out by the cath can so the s/c is receiving only pure air. Dirty oily air causes the s/c to wear out prematuerly. There is no performance gain by doing this. I simply am protecting my s/c and prolonging its lifespan by doing this.

You can buy the catch cans here. $44.99

So lets get started.

Materials

1. Jegs catch can
2. Phillips screw driver
3. Razor blade
4. Needle nose pliars

Note: Installing the support bracket is up to you. I didn't use it. Explanation is in post #4




1. First you have to cut the existing hose going from the valve cover to the intake.



2. Remove the now 2 peices of hose by squeezing the clamp together and pulling the hose off.



Now both hoses should be off leaving you with this.



3. Here comes the point in time when you have to test fit the hoses and cut them to fit.



4. Once you have the correct length for the hoses, apply a clamp to the end of each of them.



5. Now that the clamps are on it's time to slide them onto the side stems of the catchcan and tighten them down.



6. After the hoses are attached you just reattach the hoses back where they came from and you are done.

 

Wow really nice How To CT, I think I will order mine right now

 

So did you use the support bracket with the catch can or is the hose the only thing supporting it. Just wondering

 

I ended up not needing the support bracket. The catch can sits there nicely and doesn't move.

The clamps keep it in place. If you use the bracket you have to drill it into the top of the firewall. By doing that the stock hoses don't reach the can.

You would have to cut new hoses to reach the catch can. The problem with that is the angle at which the lines run to the can. The lines crimp so the flow is cut off by at least 50%.

The stock hoses are pre-bent so no crimping of the lines when you do it this way.

BTW, thanks Kyle.

 

I was thinking that it probably sat there good enough with the hoses attached but I figured I would ask about the bracket. The jegs catch can looks really nice and good write up on how to install. I think I might have to get one of these to help keep contaminents out of the supercharger.

very nice, i may be ordering this soon, excellent detailed write up.

 

look very simple. good stuff.

 

i'm a noob so cut me some slack.
what does a catch can do?

 

newbie, do you know how to read? I didnt know what it did until I read what the guy actually wrote.

 

ooops

 

newbie

nice write up CT

 

Thanks a lot guys. It's a super simple mod that will help the life of our blowers.

I'll keep you guys updated on how it's working out and how often it has to be drained.

If you have any other questions Inferno just ask. Again thanks guys.

 

Nice idea and nice write up

 

does it have some sort of drainage plug or do you have to take it out to drain it?

 

Very interesting... I'll keep this in mind.

 

At the very bottom of the glass jar there is a drain plug. You just turn the pin to loosen it and drain the oil.

 

Actually you have it backwards. It shouldn't suck anything through that line while in vacuum. There is no vac before the tb where that line runs to. The line you are putting this in supplies the clean air that the pcv system removes. The problem with it is when you are in boost pressures can leak past the rings (blow by) and get pushed through that line into the intake. Of course it's all possible that an engine can be getting blow bye while just idling/cruising, but then you are having some issues.

 

very nice install...though i couldn't spend the 50 bucks for a 10 dollar filter.. lowes ftw

normally when driving between oil changes i get not even a table spoon in the container...but its enough oil that over time would certainly puddle through the induction/throttle body/blower.

its not as bad as i have seen on my brothers sti or friends srt, but for 12 bucks...can't go wrong.

 

That's good stuff. You could definitely do it cheaper. You should toss a little how to in here on doing it the Lowes way. Good to hear it's working for you.

 

nice mod, just for the heck of I'll link to some other catch cans just so people can see some different ones...I'd go with the one you have though, its way cheaper

I picked one up from home depot the other day. I'll post a pic up of it. The install would be exactly the same as it's exactly the same thing. Which is an air/water seperator for an air compressor. Actually, here's the link to the page with it. For some reason it looks a little different, but it's the same part # as mine. Probably just an updated one. All you need is to spend $3 more bucks and get the brass barbed fittings and you're set for around $15. The only difference is that it doesn't come with a mounting bracket. I'm sure you could find something there if you wanted it, but it's not needed like your install. Also included one for a little more from sears. HTH

Thanks for those links blueta! That will help a bunch of people.

Also thank you for your link BLKblurr06.

 

just to let you guys know, you can pick up an oil seperator w/filter for a compressor tank... it's the exact same thing.. for $10 at Home depot.

 

Yeah the link to the Home Depot jobber is in the 1st post. This way people have a choice.

I can't remember have you done this yet Paul? Do you plan to?

 

I actually have a b woody catch can... just haven't installed it yet. since I never have time to work on my own car anymore.
yeah just saw that in the 1st post... I was too tired to read this morning lol.
