2G Catch Can install, this it?

Yours looks right, hose looks tight but right.

Got it installed in the best spot I could find for now

I got thousands of check valves here at work, I’m guessing they’ll work. They are rated for upwards of 50psi.

You're going to be in for a bad time. There was a test done, I think on the 'link forum, where it showed that the PCV system only sees 1-2 psi/vacuum either way. The softest check valve wasn't even really up to the task of balancing such a sensitive tipping point. Someone suggested using a fuel cell tip-over valve which seemed promising.

You want to PULL the blow-by out of the crank case. Simply running 2 lines from the valve cover to a can with a filter on top is the same as just having no lines or can. There's no way it can pull the blow by out because 1 there's no vacuum at all, and 2 there's a filter on the can making any vacuum source useless, so you're at the mercy of the system building up enough pressure to push into the can. Looks neat, even with the -AN fittings for oily air that sees basically no pressure (some would suggest it's rice :] ), but it is counter productive. If you have a drag car you can get away with this, but any other scenario it should be a sealed system with a vacuum source.

For a vacuum source tapping the intake pipe as close to the turbo inlet as I can get has worked amazingly for me. There's always vacuum there and the more the snail spins up the more there is.

I guess I am not following, he is using a sealed can. The photo he posted in the original post is a random one he pulled off google, he says it in his paragraph. His setup will work just fine, it matters more about the material inside for what it will remove before entering the intake pipe.

The check valve I post earlier has no problems at all flipping with the pressure through the PCV. I have been running this setup for years and no signs of an issue with the valves. I replace them yearly to keep them clean but haven’t had one fail.

Did you really say AN fittings can be considered rice? Haha I have disagree with you, they just add another finished look rather than a slip over. Are they needed on the CC or low pressure hoses? No Do they look better than a slip over hose? Most definitely.

A team of engineers for every automaker outside of Tesla thinks otherwise. You literally just agreed with what I typed and defined them as rice. Big wings have their place too. But if in the next breath you're going to then say they're for a better finished look and not necessary, welp.

-AN fittings and lines for the PCV system is ridiculous and there's no point in using them aside of looks, to which your comment above just supported. Virtually no pressure or vacuum is present in the system and it's moving oily air. Why is hundreds of dollars of -AN stuff the norm aside of looks? If you're using a race part only for "another finished look" and to "look better than a slip over hose", then it's the effing definition of rice.

Appreciate all the replies, but my DSMing is over with for now. Ended up trading the 1997 Spyder for a 2007 Audi A4 Quattro.

Who peed in your Cheerios this morning?

Saying the AN fittings look better than a slip over doesn’t mean they are rice haha So if I buy a set of aftermarket rims because I like the look better than stock rims, it’s rice? Gtfo You can say AN fittings are “ridiculous” but majority of those who put a lot in to their cars prefer it as it goes along with the other lines converted to AN like fuel or oil lines. Having something with a “finished/clean” look doesn’t make it rice.

Don’t get me wrong here, I have slip over hoses still in a few spots and don’t have any issues.

So you got rid of both?

i sold the black one right after I bought the red one, and I had no intentions of selling the red one, but a guy offered me a 2007 Audi A4 with 80k miles on it pushing 350hp and with me and the wife having 3 kids it was hard to turn down.

That’s a good deal. Audi’s are nice. I forget what exactly but they have an issue with timing chains coming off and damaging the head iirc. Might be the guides so look into that because it’s super common.

 

[Stapl3]

.

You're right. I apologize and abide.

Nice work on the Audi, they really are great cars. My good friend has a few of them just like that. As for the timing stuff, sadly true. It has to be done and changing it like assembling a Rolex compared to our cars. I've been told a lot of people bail on them rather that doing it as it costs so much, sooo keep that in consideration if yours hasn't had that done.

yea that’s what I’m hearing. It’s got a new motor in it, so hopefully I won’t have to worry about that for a while. I kinda miss the eclipse, but with the Audi being 4 door it was perfect for us, plus it doesn’t look bad. Only thing is it’s straight piped and super loud, but not Honda 4cyl loud, it actually don’t sound bad. And it’s got a Forge Dirverter Valve (which I never heard that term before, always called them BOV) and when it blows off, it sounds just like you are spinning the tires over on dry pavement.
