I just want to confirm this b/c ive read so many PCV treads my head is starting to heard.

A few people stated that leaving the PCV in place and just letting it vent to the atmosphere and capping the nipple off the manifold is will and just run a breather filter to the valve cover.

Is this correct for a turbo setup and any drawbacks besides pollution?


Thanks

 

bump...

SO much info out there is there any performance issues with the setup above

 

I spoke to Ken at Peakboost he said to let it vent to atmosphere, Shaun at church said the same thing.

The kicker is Bubba said to leave the PCV in place.

Why are different tuner suggesting different philosophies on a boosted setup. This is what is confusing just like the many threads out there...

Id like to know on a Boosted car which is best. Leave in place or let it vent to atmosphere???

Thanks

 

Vent it.

 

im venting mine

 

loose the pcv valve, and run it like this below, should be pretty obvious by the pics, bottom one is the drainback from bottom of the catch tank, the other 2 just route to the catch tank in the side. i made these but you can buy them from traders on here

 

Ok Vent it is thanks guys.

One question with venting can i leave the PCV in place and leave the hose on just point it to the floor so the fumes stay under the car. Or do i need to loose the PCV valve on top of the can all together and if i want to run a hose i need to buy another 90deg fitting that fits in the can. That was my concern a fitting that is the same size as the PCV if i can find it at NAPA or other auto parts or not.

 

Where that rag is thats where the freeZe plug goes. And isnt it best to let all of the oil out of the catch can instead of putting it back in. Just wondering

 

no the rag is where the oil filter goes..

the drain back hole is the bottom fitting with the little 'L' bracket keeping it secure.

i personally prefer the drain back system, as its like the original black box, running without a drain back would mean you constantly need to drain the catch can when it gets filled up, and keep topping your engine oil up.

 

Vent it..

I have block plugs and have deleted the oem catch and have a auto drain back setup like a t1 can.

My question is, Is this the port that goes to the top factory catch can? What are you all doing with the port that goes to the top of the factory catch can after the can is deleted? I may have "pointed" at the wrong port in this pic.. Anyone get what I am asking? Its 5:30am im tired.


Here is a pic of mine, You can't see the port I am referring to.

 

yep thats one of the 2 pipes that went to the top of the black box, the other comes from the pcv.

blank that hole up are your good to go.

 

No its not, that is the water outlet for the factory oil cooler. Some b-series have it, and others have it capped off, just like his picture. The outlet for the black box is at the very top of the block, right about the can.

 

the vacuum of the motor will pull the oil back out of the catch can i do not see a need for 3 lines on the back of the block

 

thanks for all the replies guys this is very helpful for me and anyone else who might have a similar question. I will leave it vented and keep the oem black pcv can in place so the oil can drain back when there is vacuum.

But i would still like to get an answer to this.

"One question with venting can i leave the PCV in place and leave the hose on just point it to the floor so the fumes stay under the car. Or do i need to loose the PCV valve on top of the can all together and if i want to run a hose i need to buy another 90deg fitting that fits in the can thats a standard fitting not a pcv valve. That was my concern a fitting that is the same size as the PCV if i can find it at NAPA or other auto parts or not."

 

jetspeedz here is what i did before i got a catchcan. i took the pcv valve out of the car then i cleaned it up a little with some brake parts cleaner. then i cut the bottom(bigger part that goes into the black box, you should look in it and see a piece of metal). when i cut it i cut off a very very minimal amount, only enough to empty the contents inside. its been a while since i took it apart or even looked at one but i believe all it has is a small piece of metal inside and possibly a very weak spring, but im not sure about teh spring.
Attach a hose to it and just vent it down towards the ground, but make sure its secure and isnt gonna get caught up in anything(axle..) thats it.... oh yeah i put a small breahter on the valve cover... anyways i hope this helps!

 

M16x1.5 thread. Use Honda P/N 90083-PG1-000 for the BOLT, SEALING (16MM) from any B-series gear housing if you want to cleanly delete that port for the oil-to-water cooler.

Use 1/8" BSPT plug.

Not really directed solely to the person quoted, but it was easier to simply quote since you've already established the known landmarks.

 

Ok so you did not really run the PCV you modified it so its a regular 90deg T fitting correct. That is what i need to know if i can leave the PCV as is and just point the hose to the ground or do i need to Remove the PCV and get a basic 90deg T fitting? What is the negative side of leaving the PCV vented. I would think this is a good idea b/c the PCV itself acts as a check valve and only allows air to escape the chamber.... correct

 

Will there be a lot of oil coming out of that hose under boost since there's no PVC?

 

Kinda on topic...Could I delete my pcv and run my catch can drain to its spot on top of the black box?

 

So to be clear do i need just a straight through 90 T or can i use the PCV and just leave the hose dangling and what is the negative effects of using the PCV instead of a straight through 90 deg fitting?

thanks

 

bump ok guys leave pcv in and just dangle the hose or the PCV has to come out in favor of just a regular fitting and dangle the hose...

 

I think what B16Civic93 meant is that if you remove/hack the inside of the PCV so it transforms itself into a 90 degrees fitting instead of a PCV valve and then you can direct the hose to the ground instead of the intake manifold.

But my question which hasn't been answered yet was will there be a lot of oil going throught that hose under boost?

 

I took it the same way but i want a confirmation. I'm also very curious about your question as well.
