Just wondering how you guys have run your catch cans on the h22, if anyone has any diagrams of how you did it that would be great

 

TTT

 

Diagrams? Find the catch can that you wish to use, either move or retain the stock PCV valve (moving it to the catch can is the better idea) and route the line to the catch can and then back to where it attaches to the manifold. Not all too hard to do.

 

there still is a proper way to do it, maybe I will just T it into the exhaust......

You'll be burning oil like a mother then.

The proper way is to take the line from the intake manifold to the PCV valve on the valver cover and throw it away. Run a hose from the IM to the catch can then run a return line from the other catch can port to the PCV valve.

Personally, I do not run it like this. I leave the IM/PCV valve line alone and instead I simply run it from the breather located on the valve cover then run another line into the atmosphere. I had a -6an threaded bung to my valve cover in order to run the -6an steel braided line as well.

 

Ya but I don't get what is wrong with running it straight to the exhaust but blocking the pcv valve, because the exhaust will suck out all the blow by, sure it might suck up some oil to, but it shouldn't be to much..... but more info the better

 

You can run it to your exhaust but keep in mind there will be some (some meaning minimal) oil that will go into your exhaust. Then it will smoke and you will wonder why you are blowing out blue smoke under load from your exhaust. Also, when you run it into the exhaust you are creating a spot where 2 flowing gasses will combine with one another. This can cause a turbulence in the exhaust flow.

So if you MUST do this then run it into the exhaust at the minimum angle possible. Running it into the open atmosphere or the proper way is your best bet... and the cheapest.

 

ya but running it into the atmosphere creates no suction what you need, and I still don't undertand the proper way. Do you have any diagrams or pics or anything thanks.

 

The breather cover does not require suction. Most turbo honda's just put a small breather filter over where the stock line ran from the valve cover to the intake. The purpose of having this under load of FI cars the crankcase ventilation is high and oil usually splashes out of the breather area. Like I said, you can run it either way. Basically if you install the catch can in the middle of the IM and the PCV valve it does not alter the system. Instead it drains out the mucky oil in the process. I routed mine differently because I do not want those fumes re-entering into my engine.

This topic has been beaten to death in the FI forum, do a search in there and I know for a fact there are a few diagrams floating around.

 

k thanks
