in skylines, the radiator cap is lower than other parts of the cooling system, hey do this so the front of the car can be lower.. that is why you need to bleed the air out of the bleeder in the inlet manifold..

the breather tank moves the cap higher than everything else.. so if you mount it on the strut tower, with the second cap above the engine, it now becomes the highest point and all the air in the system will gather there, allowing you to easily bleed the air from the system by simply running the engine and filling it up..

rb's if not bled properly will gather air in the cylinder head as its higher than the radiator and the cyl head temps will get high and cause damage also the pressure of the cooling system will be low and it will do bugger all.. so its important to bleed them. breather tanks are better value for money than catch cans if you ask me.

cheers

thank heaps mate

how do u hook a breather tank up the right way as its in japanense

im assuming that the bleeder has a radiator cap on top.. what has come in the kit??

most of them have a t piece that plumbs into a coolant line, or the coolant line gets replaced by the lines and bleeder tank.. just like a catch can arrangement but with coolant instead of blowby.

The picture looks like it explains it. Yes you need to get a tee for the bottom radiator hose. You can buy these for water temp sensors. You will then need to get a nipple that screws into it to attach a hose to. The top end looks like it sits between the over flow bottle and the radiator. the highest to the overflow bottle the lowest to the radiator. The other one can be capped off. Just make sure that you mount the top of it higher than the cap of the radiator so the air rises to the breather tank.

that is how i trought it would go just wanted to make sure

it has to sit higher then any coolant running around right so the dose that mean it has to be higher then the coolant line it the top of the turbo has i have a hi mount

      After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
