Your brake master cylinder is leaking, out the back. But you may not see the leak, because it is leaking into the brake booster. It has probably eaten the rubber in the booster also. Now you have brake fluid in the booster, which travels through the vacuum line to the inlet manifold. Now you have brake fluid being burnt in the motor, and smoking out the exaust. Maybe... Am I wrong?

You've mistaken the brake fluid can for the air filter 
Nah, probably something along the lines of what Jonny2TG said

Ok, thanks for the ideas so far, I pulled the brake booster line to the intake off yesterday and checked it for fulid, it is dry and clean so there goes that!
Just took it for a drive and it is driving as normal and the smoke has prettymuch stopped? maybe it was just a contaminant in the fuel or something?
But there is still something wrong, the back of my car is getting covered in black shit, so I am thinking that that smoke that was pissing out the back was black and not white and it was just the light in my garage that made it appear white?
I started the car and took the radiator cap off, no bubles, drove it for a while and then checked the radiator cap and the oil filler cap and they are both clean and normal, no contamination. So I dont think it is the head gasket?
Anymore ideas?
It blows a shitload -and I mean a shitload-of smoke up high, I always thought it looked white in my rear view mirror but maybe it was just my eyes and it is black? What does this mean if it is black, and also if it is white?
The fumes that were coming from the car on saturday night were really smelly, I dont know what it smelt like, but it was a pretty foul smell?
With the black shit on the back of my car, this used to happen even when I had the 4A-C, could it be my exhaust? It is only abuot 6 months old?
When I started it just before and went round to check for the smoke I could see liquid being spat out the exhaust pipe, which is exactly what the 4A-C did aswell?
Someone Help me please! I am so stumped and I really wanna fix it so I can drive without being worried its just gonna die underneath me!
Thanks again for any info anyone can give me!
Cheers.

Hey WHITCHY
Sorry to here about car dude....
Well not sure if this coud help but I doubt it is your exhuast as only brand new exhuast like only for the first 2 days will be blowing white smoke. Have you checked your computer sounds like your running very rich... the things you mentioned occured to a friends mazda and it was spitting out oil from the exhuast. Ill ask a friend of mine to read your posts and get back to you.
Hope all is good

Sounds like its running very rich. Has it got aftermarket computer? Probably needs some tuning again.

Yeah it is running hell rich! I am getting about 200-250Kms to a tank!
When a mate was following me the other week his eyes were stinging from the exhaust fumes. 
I started off with an AUS ECU and then swapped to a JDM ECU, back to AUS ECU and nothing has changed at all!
Can it be something to do with the fuel system in my car, cause the 4AC before the 4AGE was exactly the same towards the end of its life in my car, but when I first got it it was good for 400Kms to a tank?
Is there any way to adjust all the mixtures or is it all done with the ECU?
Someone must have had a similar problem to this before or know how to fix it?
Thanks for the help so far!
Cheers.

one other thing I just remembered....
Cause I have extractors, the spot for the O2 sensor is all the way under the passenger seat, I hooked it up by cutting the wire and joining it with a long piece of thin speaker wire I had lying around? it is only the single wire O2 sensor and I was told that having them more than 1.5Ft away from the head was a bad idea? But I dont wanna sample off only one cylinder!
Could that be affecting it somehow?
Cheers.

the stuff coming out the exhaust more than likely is water (condensation) thats built up overnight in the exhaust. Does it dry up when left on the ground to dry.
The smoke could be from worn rings or even a valve stem seal thats gone hard and now leaking.
The black shit on your car is because the car is running super rich. The computer will have to be tuned or a sensor is packing it in. You have to start eliminating this to find the problem.
The exhaust sensor is to far away, it has to be where the exhaust manifold or header pipes come into one pipe.

Yeah its factory ecu on Whitchys 4age.
What sensors could cause it to run rich?
I've already tested the TPS and thats fine.
What else we got that could effect fuel mixtures, coolant, air, map? anything else?

Ok Been doing some more thinking....
On the intake where there is a valve with 3 spots for vaccum lines one running to the fuel rail (?into the fuel pressure regulator?) and the other one runs to the MAP sensor, and the 3rd one is blocked off.
On my intake the 3rd one is blocked off with some really hard putty looking stuff so if this is leaking and sucking in air could it be causing it to run rich?
Or if one of the vaccum lines to the MAP sensor or the fuel pressure regulator is cracked could it be responsible for making it run rich?
Turbo RA28 suggested that the return line could be blocked, what effect would this have?
Thats all the ideas I can come up with for now???
If anyone else has any more ideas or suggestions please feel free to share, it is really pissing me off 200Kms to a tank and filling up oil and coolant once every few weeks!
Could it be something to do with the wiring? I DONT KNOW PEOPLE!
HELP ME OUT!!!
Cheers.

Yeah I suggested something with the fuel pressure regulator, fuel return line.. Maybe some stupid amount of fuel pressure behind the injectors making it run so rich?
As by the sounds of it when it was in the old AE82 it was ok. So it's likely something that has changed between ae82 and ae86 conversion.
With the wiring, all the sensor wires arn'nt really touched, map, tps, coolant, dizzy, etc all are wired directly into the ecu.
Unless its freaking out and going into a error mode or something and runnign super rich.
Can anyone confirm if bigports should have a knock sensor? As i've had a 4agze with this problem and it was because the knock sensor wasn't connected and the ecu richening the mixtures right up.
As for that shitty vac port on the inlet manifold i'd try getting a good one and bolting that in, put new vac lines to the fuel pressure reg and also map sensor to eliminate any problems there.
Get mechanic to do a fuel pressure check to make sure thats correct.
If all that checks out ok then i'm thinking we have to try see if we can get some error codes out of the ECU.
Anyone know about bigport 4age ecus, i'm assuming you can wire up a check engine light? Any instuctions on how thats done? I know the bigports dont have a diagnostic plug like the smallports do. I think its just 2 pin plug you jumper together?
Cheers

Also noticed that Whitchys wiring loom doesn't have provision for a injector drop resistor. Well I dont think it does anyway.. Dont remember seeing one when I looked at it.
But my bigport 4age does use one.
Whats the go there? Do some use them and others not? As I know Whitchy is trying different ecus (jdm, aus) to get it working. I'm guessing there must be some differences in the versions not requiring the resistor?

my 4age bigport in the aw11 had a diagnostic plug
there are pleanty of websites with wiring/pin out diograms for bigport motors

Ok, just did a compression test the other day and got:
(1)100, (2)100 , (3)90 , (4)110
NOT HAPPY JAN!!!!
This would indicate valve stem seals and rings are farked doesn't it?
And that would explain the chewing of the oil, and the smoke up high!
but seals and rings wouldn't affect fuel and coolant usage would it?
Looks like its time to save and get a GZE like I should have just done in the first place!
any more suggestions on whats causing the ridiculous fuel usage? Its gonna be hard to save for a new motor when I have to fill up every 200kms!
Cheers.

Anyone correct me if they feel I'm wrong.
1/ I think your up for a head.= coolant usage.Check if your blowing steam out the tail pipe.
2/ If #3 not working extra fuel to keep up the rev's.
