Hi guys,

I've had a read of quite a bit of the catch can setups, however it has honestly left me a bit confused so I just wanted to clarify before I went ahead.

Can you please let me know if the following set up for the catch can is effective from the pics below?

Notes:

Original - 1:

this is how it is currently without the catch can in place.

The green dot means it is blocked off there. The intake manifold has instead been linked to the ViPec ecu.

The green loop means it is connected between rocker covers

The green snake to the right is exhaust side connected to the intake

Original - 2:

this is what the planned hosing will look like. Modified hoses are in blue, green means they're the same as before.

The exhaust side has been re-routed to the catch can

The other port on the catch can has then been routed to the intake.

Cheers all

why not just run both to the catch can? and plug up the intake? this will stop your oil vapour being recirculated through your intake and making everything dirty and lowering your power....not sure if its legal tegal to do this in WA though.

As above ...your plan looks ok. Do you have some form of baffles in your catch can? If not and you are getting too much oil into your intake you might need an additional oil/air separator and/or put some mines baffles in the cam covers or make your own.

If the legalities of it all weren't a concern, this would work wouldn't it?

Thanks for the replies everyone.

I'm not quite sure, I'll have to contact the people who originally made it and ask them as I can't visually inspect inside it.

So I can keep the other port on the rocker cover intake side blocked off?

And that line from the intake manifold is fine going to the ECU and not connected somehow to the other vacuum lines? Just concerned that I need to connect in the PCV valve to the system, that's all.

Many thanks again!

Yep route both cam covers to the catch can and you could block off the pcv valve too. The line going from the intake manifold to your ecu is presumably for the map sensor and should not be connected to any other line.

If it's a Sri catch can there's a hidden breather in the middle on the bottom. Don't know if it provides adequate venting capabilities for a modified engine as the openings very little

Grab a bar, a half inch ratchet extension will do, and gently turn the fittings in the rocker covers to face each other as well. Be careful with how hard you push as the fittings can be damaged if you have to push them too hard. Then you will have one cross over hose between the 2 rocker covers and the 2 outlets facing forward going to the catch can. Makes it look a little less obvious to the boys in blue. They should end up looking like this, bare in mind these rocker covers arent sitting correctly, but i am sure you can see what i am getting at. It just means there is nothing blocked off and it looks neater as well

Where the can sits isn't a problem there's enough space there but if you look up the breather on the bottom, the gap between where the tube ends and the top of the catch can is very small compared to the surface are of most breathers which seem to be about -16

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
