I bought a catch can off ebay a few months back, I've been reading up on all the different ways to run the hoses...I just need someone who knows their ---- to give me some input here. It's my first turbo kit, i want to do it right.



Thats the 2-way layout that **** posted, plus the 2nd check valve that projekteg suggested. I will be using Purolator PV1029 PCV valves, apparently they are leak-proof. Does anyone see any problems with this? I understand that i'm circulating the gases/vapors back into the atmosphere through the exhaust, but thats the least of my worries. As long as theres vacuum at idle, and circulation under boost, thats all that really matters right?

open your trunk and then slam your dick in there

Doesnt sound anywhere near as fun as slamming my dick in your mother ***. ---- off

2 hoses to the fittings on the back of the block(buy them from Majestic) and a breather on the VC. and ur done.

If you don't understand, read this.

you will have a leak problem in boost. from the intake manifold hose running to the T you will be pressurizing everything you setup is no good just run the stock pcv system and then vent your valve cover to your can and get your vaccum in boost from the inlet of the turbo. its simple and easy. i can draw something if you are confused. a catch can is so your bottom end can breath and evacuate pressure while in boost. your exhaust SHOULD do it but i dont see it being enough.

so just fix and look at where you have that T it doesnt look right to me.

Honda setups are kind of fucked due to both the pcv and vc breather "supposedly" receiving fresh air. Basically the VC breather sucks fresh air in and circulates through the block to be sucked out by the pcv and all excess oil is supposed to get trapped in the catch tank below it. Doesn't work that way though, as most Honda engines actually "blow" oil out the VC breather due to the pcv vacuum source not being enough to keep up with the blow-by.
Most people will say to just vent them to the ground, I've done this before and I can tell you that it doesn't work too well. The excess pressure that builds up under boost will show a rise in oil pressure, and then a sudden drop as pressure releases or blows past something. The block and VC both really need to be modded and upgraded to keep up with the blow-by, but it's a lot of extra work.

This is on a D16y8, not a B-series. I dont use the 2- fittings on the back of the block, I gut my PCV valve and go from there, to a T at the breather, to the catch can. Then from the other fitting on the can to the slashcut barb in the downpipe...Having if faced away from the direction of airflow in the downpipe will produce enough vacuum under boost to vent the crankcase, having it routed to the Intake with the check valve makes it so there is vacuum until i'm under boost. Remember I took this straight out of ****'s sticky thread. Projekteg came up with the check valve to the IM idea, and it makes sense when you think about it, but I just havent done this before, I was hoping to get some feedback from ppl that have run this type of configuration before, or know of ppl running it without issues. The catch can is sealed, and the check valves i'm using inline don't leak pressure so the crankcase shouldnt ever be pressurized.

ohh i see im sorry i didnt see the check valves, only think i dont know about would be the exhaust creating enough vaccum, i dont think it is a whole lot.

It all depends on the backpressure created under boost. For a n/a setup the slashcut really wouldn't work too well, but because on a lot of boosted setups backpressure can usually exceed intake pressure by up to 2 or 3 times the amount, it will have enough force through it to create a powerful suction. I ran a slashcut on an older setup and put a vacuum gauge on it to see (b18a1/16g) what it really made, and the average under boost was at least 22 in/hg.

thats awesome then how do you mount the slash in there? like open end slash opposite the force coming at it?
