headgasket leaking? or?

ok, done a search but i think i would need a more precise diagnosis onto whats going on..
i got a KE30 with a 4AGTE, AFM/standard management, T28 turbo etc etc, been in the car for 6 months, drivent about once every week, loads of fun!
i took it out yesterday after a week of not driving it, and came across a problem - after i gave it abit up a street, it started to misfire (like on 3 cylinders) every time i gave it throttle. But this was like 30mins into the drive.
So i took it home and checked things i could imagine to cause this problem, leads, plugs, igntion, fuses etc etc...but the only things i could see were:
1. abit of water in all cylinders, not alot, but enough to notice if you peer down the holes...no.2 was not too bad tho.
2. spark plugs had a pretty noticeable build up of carbon
the radiator fluid was not too bad - as in milky wise, but i topped it up with more fluid.
-hasn't overheated in ages too.
So i took it out today for a drive and it was fine, UNTIL it came on boost and it began to do it again
went home, took out all the plugs, cleaned em all with a wire brush and i absorbed most of the liquid within the cylinders - took it out for a quick drive and it *seemed* fine (couldn't drive it hard)
are these the tell tale signs of a BHG? or could it be an electrical fault?
I know water in the cylinders is definately not good, but it just seems unusual that between yesterday and today, it ran fine for 10 mins, and then other times it would not even take off properly
ps. compression test soon, but i just want to eliminate other things beforehand

mmm well the misfire and black plugs would definitely be related, so i would ignore other ignition issues for the moment.
are you certain it was water and not fuel?
if its water then theres no other way, other than a bhg.
its a bit strange that its in i all cylinders though, unless it has cracked beside each cylinder..?
how much water are we talking exactly?
do you mean enough to cover the piston top?

no, just a skim of liquid in each chamber.
basically i ripped abit of paper towel, put it on an extension claw tool and it absorbed the liquid within about 2 dabs in each cylinder.
I'm not sure if it was water/fuel - but my guess is water and it definately was in all cylinders- not so much in 1 of em tho.

milky coolant means BHG-not too milky is bad as well
Should be green,pink/red or even clear but not milky.

hmm
checked the radiator fluid last night and it is clean as a whistle (green/transparent and topped up)
I took the car out and it boosted up fine with no dramas, i also bought some 'stop leak' for gasket seals and poured it into te radiator. Has anyone had success with these products?
also is there any other way water could have gone into the cylinders other than a BHG ?

cracked head.. but you dont want that.. when my headgasket went on my supra it started out just like you said, eventually it got worse and worse.. A good way to check is take off your oil cap and clean it out, then take your car for a drive, not too hard but not like a granny, when you get back check the oil on the oil cap, if its milky then BHG.. if there is no oil on it and its dry then go again and drive it a bit harder.
Another good way to check is see if your radiator is sucking water out your overflow or if its just filling it and its overflowing.. If it still draws water from the overflow then your gasket is OK and its another problem. but if your overflow is overflowing after a bit of a drive then BHG.. good luck mate..
make sure you find the problem coz it can (and usually does) lead to worse shit
