Thanks for the advice Ero. I was ready to burn the bitch today ("You like fuel that much? Well how do you like it now, bitch??" ) Four years of leaking injectors, even after spending R10000 to fix it, is enough to drive any man insane. Especially one as short tempered as me.
Took the bloody fuel rail off 6 times! Each time I put the fracker back in, there'd be a little fountain or a stream. Even before I started the bloody car. Tried everything - different injectors, different o-rings, rubber tape, plumber's thread tape. I was ready to give up but the last combination of injector, o-ring and thread tape seems to have done the trick for now.
I say "for now", because this is a temporary fix. I have mis-matched injectors, altho they seem to flow the same and hence the engine is smooth. Also the thread tape might get eaten by the fuel, but at least not as badly as the rubber tape. My gawd, have you guys seen what happens to rubber tape in fuel? It MELTS! Right before your eyes Plus I can see these other injectors are getting a little damp up atop, even though there is no leak now.
I just hope it lasts a few months while I find an alternative solution to this problem, which will no doubt involve brand new injectors, probably 440cc.
Damn, I almost didn't think I'd make it tomorrow...

toby, remember the fuel pressure is at around 2.5 bar right.
so you should check for any little scratches of any kind on the holes on the fuel rail. the o-rings at the top of the injectors are there to create a seal, but if the steel is damaged even with a light scratch, the fuel will find a way through.
another thing is to be careful not to damage those o-rings when you're inserting the injectors into the rail. they so easily can get squashed and then stretched or broken. try to use a little bit of red rubber grease when installing the injectors to allow those seals to slip in there easily!

So the fuel started to leak again
Luckily, ChemCool supplied me with another fuel rail (thanks dude!). To be sure, I put my original injectors back on with good o-rings and nothing else. Two were leaking (the two with discoloured connectors). I could see it bubbling from the body of the injector between the plastic and metal. Those 2 injectors are shot. So I replaced those two with another 2, and now it's working! No leaks, and no funny thread tape or anything.
So it was indeed a combination of fuel rail and bad injectors! Can you believe my luck?
This car has reached the end of it's lifespan though. Everything is falling apart. A clip disintegrated just 'cos I bumped into it gently. Last night I was driving home and something breaks in the engine bay. Limped home only to find that the bolt holding the alternator broke off! It's going to be a real struggle to keep the car together from this point forward
