nah wont kill it lol, you may just get some extra crankcase pressure, keep an eye on your dipstick and check the level of the oil in the can

thanks alot BROTHER

Just remove the filter & Block it where it came off with a cap.

Run the hose from the PCV valve to the can, then from the can to just before the

turbo intake.

the factory setup draws in oil fume anyway so its not going to be any different.

You can make it better by if possible run a foam filter inside the can so it traps

as much oil as possible from returning to the intake.

the tyre of catch can I have has a removeable top so I can do this.

It would be a better option to purchase a non atmo type can.

the whole idea is to remove crankcase pressure with less oil contamination as possible

while keeping it legal.

thanks alot

If you removed both pcv lines it shouldnt be oil unless it is coming through or around a piston lol.

I know its been done to death, but whats the best way for us to fit a catch can to our cars?

By default, on a stock XR6T the front breather hose goes back into the intake (pre-turbo) which sucks the crankcase fumes out and the rear one with the PCV valve went into the inlet manifold so that it can suck in the crankcase fumes when its under vacuum and wont push anything back once the intake system is making boost. (I think that's how it works yeah?)

After fitting my full 1000hp Plazmaman kit (plenum..etc) the rear PCV outlet goes into the bottom of the plenum, and the front one goes into the pipe between the filter and the turbo.

What would be the best way (for the engine life) to fit a can up? I realise having a little bit of oil going into the system is good for the turbo isnt it? but then it builds up on the inside of the cooler, plenum, throttle body..etc which can affect performance.

Option 1

Leave the rear hose with the PCV valve connected to the underside of the plenum, so that it can draw in any fumes at vacuum/idle, and connect the front hose to a catch can. The catch can has a filter up the top and vents any filtered air into the atmosphere. I then replace the pipe between the air filter and turbo with one that has no fitting on it.

Option 2

Leave the rear hose with the PCV valve connected to the underside of the plenum, so that it can draw in any fumes at vacuum/idle, and connect the front hose to a catch can. The catch can has a return hose which goes back before the turbo.

Option 3

Have both the front and rear breather hoses going into the catch can, and then have a filter on top of the catch can, venting into the atmosphere. I then replace the pipe between the air filter and turbo with one that has no fitting on it, and blank off the fitting on the underside of the plenum.

Option 4

Have both the front and rear breather hoses going into the catch can, and then return the air back into the fitting at the front of the turbo. This will then recycle the filtered air (through the catch can) back into the system.

option 2 would be the easiest one and the answer you are looking for to remove the oil from the intercooler and associated plumbing. If you were to get a custom made catch can, id plumb up both - option 4.You must remember its illegal to vent a catch can to the atomsphere. I just installed a catch can plumbing (option 2) and used a generic can but added a baffle in the can. The generic cans are only very basic, using volume to separate the oil from the air. The best cans are baffled which slows the oil/air enough so the oil separates from the air and drops to the bottom of the can by gravity. There is a bit involved in designing an efficient catch can.

Have a read of this if you want to learn more on air/oil separation:

Great link there Pube.

My suggestion would be to run a canister as per the very last picture but

fit a gauges filter internally to the exit side of approx 20microns so it allows fume only

and keeps as much oil away from the exit.

Other than that a baffle just below it .

that is an excellent read. ive heard people talk about catch cans and know what a pcv does but had no idea how oil separators worked. I think I'll look into putting one on....
