Please ask Craig what they cost (calan 3 posts up) as I purchased them a while ago and don't know what they currently cost. I can tell you that they are extreemly nice and I paid less for them then my buddy paid for his generic greddy catch can that is too large for a 2.0L.

Looks good man, you wouldn't happen to be getting ready for the car show would ya?

Should work with no issues, other than the cans may fill up a little faster. Crankcase pressure should be nice though.

Hey did I hear Dave right? You also sell the pushlocks?

No... just the cans.

I can get fittings and stuff from Summit, JEGS, etc, but it cost me the same as anyone else (plus shipping)...so it usually ends up being cheaper to just buy the fittings and hose from your own source.

But... we need to stay on topic here and take any other questions to PM's.

Well yes and no. I am always in a state of trying new things and adding, or in this case fixing the car. I almost always seem to find out some new information and have to go back and fix an old ignorant mistake. The fittings came from summit and since we have a distribution center close shipping is free and fast.

Craig, I hope they fill up fast because that means they are doing their job well. It might even cure that oil leak I only get under boost.

That's the idea... as long as CC pressure stays low as well.

You'd be amazed at how many people are running empty cans (or cans with steel wool, etc), and argue that if a can is catching very much oil then something is wrong. They don't seem to realize how much oil vapor and nasty crap is being sucked straight through the can and back into their intake and IM... until they open it up.

[SexyDSM95]

I must have one!

[fallenauthority]

Looks good, now you just need to get that throttle body powder coated, takes away from the nice looking charge piping.

[genegoesfast]

I just did it actually. As well as the intake manifold, fuel rail, thermostat housing, j pipe, compressor housing etc......

[rommel rojasgsx]

Looks great, but you need to do something with that overflow bottle

[RipperXX]

I so got to get me one of these. Will be a while before I do since im no where near my car though (in Afghanistan, stationed in Germany, cars in Georgia...) So PLEASE keep making these things!


I agree about the oil though, if you read the factory manual you will even notice the only reason it lists 15w-30 is for econemy...I don't think anyone here is THAT worried about the mpg. Go thicker if anything not thiner...unless maybe you live in an area where it gets stupid cold.

Thanks again Calan for the catch cans!

[VTEC_THIS]

Got to be a guinea pig and test out one of Craig's new catch can designs!

First off, the catch can is beautiful. It was packaged very well and the design and the welds are top notch! I wish he was local so he could weld all of our parts!

We hooked it up the day we got it and so far so good. I think we’ve only driven the car hard twice since we’ve installed it but all signs of blow-by are gone. Our dipstick hasn’t popped out, no oil spray, no oil seepage around the valve cover gasket or oil cap. Also, it was smoking from our last breather catch can setup through the breather and also out of the exhaust slightly. No signs of that with this guy. So finally a catch can setup that works for us! The coarse filter media and the filter seem to be doing a really great job also. Again, we haven’t had many opportunities to drive it since we installed it but from what I can tell so far it’s an awesome design.

Another thing worth mentioning is we didn’t modify the valve cover, we just connected the –8AN lines directly to the stock valve cover ports (pretty much the same way Corey installed his). I realize if we start running into any issues, the problem would be that the valve cover openings aren’t large enough, the catch can wouldn’t be to blame.

Here are pictures of the catch can when we received it and of it installed on the car. I apologize for all the pictures but I just couldn’t help it, it’s so nice! I know our engine bay isn’t as pretty as say, Corey’s or Paul’s – it’s kind of hard to keep up with those guys though!

Pictures (two -8AN inlets, one -10AN outlet):

Looks great Keri! Just an FYI as I'm not sure I mentioned this in our PM, that side port on the VC can be tapped same as the PCV to run a bigger I.D. fitting.

[TSiAWD666]

I don't understand how that works without suction through the crank case.

[gofer]

The line to the intake (pre-turbo) apply's vacuum to the CC, which apply's vacuum to the crankcase.

[romeen]

Keri, any issues with hood clearance when you were installing it?

[godschylde777]

Ya know just when I think my Gracie is the stuff I get humbled by some great cars.

Yeah sure, but there's no fresh air source pulling fresh air on the other end, so instead of flowing fresh air in there, you're just sucking on a somewhat vacuum sealed box. Not going to get too much circulation that way.

I'm asking just because I want to know why this seems to be the case with so many catch can systems out there despite it contradicting the design of a pcv system. Really not trying to knock it, just curious if you folks are ignoring that design, or there's something I don't see.

That should all be explained in here, John.

Thanks for the tip Corey, it's much appreciated.

No issues Romeen. Of course the battery is relocated to the trunk and the cruise control is deleted so that helps too.

Wow I'm actually a bit insulted you would link that. It only confirms what I suspected which is this does not maintain the PVC system and instead compromises it.

Thanks for the update Keri. Please let us (at least me) know how it works!

As long as the can is placed into the "existing" line between the VC and turbo, it isn't doing anything to change the factory system, except to filter the air being pulled from the crankcase.

On a stock setup, fresh air is pulled from the turbo inlet into the crankcase when the PCV valve is metering air via the IM. Since the can does not block airflow in either direction, fresh air can still be drawn in via that route...so I'm not sure how this would compromise anything.

My comments have all been entirely in response to vtec_this' setup. I'm very well aware of how to maintain the PVC system and use a catch can. I realize I didn't specify that, which is my mistake.

Well I wasn't sure, since you keep saying "PVC".

Keri's setup still works fine to relieve CC pressure while under boost; they just deleted the PCV valve side of it, which eliminates fresh air ventilation during off-boost driving. That may or may not be a problem, depending on how often they change their oil or if they see any small CC pressure spikes during transition between boost and non-boost driving.

BTW - PCV valve deletion is discussed at the end of the article in the link that Brian insulted you with.

[TSiAWD666]

Oh wow that was my iPad stupidly auto correcting!! Pcv pcv pcv

Only the speculation is discussed which isn't anywhere close to an engineering-based answer. Anyway you're just confirming that this is still a deviation from the system and a compromise. That's what I asked so thanks.

Moving on...

So when do these new cans go public?
