Pop, Smoke, Funny Burning Smell...

[foznice]

the story goes like this:

My car - r32gtst came over without a belt thrown over the AC compressor, and a lot of cooked rubber stuck to that particular corresponding section on the crank pulley. So I bought a new belt dayco belt for the AC Compressor..

So I took the PS belt off, no problems there.. then the alternator belt/water pump belt, still no problems. And I began working away at all the cooked rubber on the crank pulley.

Because I was working away at the crank pulley, I was working at it from underneath the car, with a knife and a wire brush, picking/scratching all the little bits of rubber from the crank pulley.. because I was working underneath the car, I only have access to a certain section of the crank... So I would clean a section of the pulley, crank the starter motor quickly without starting the engine, and hopefully expose an uncleaned part of the crank for me to clean..

So I cranked it once, cleaned it, all good.. Second time I hear a pop, and looking throught the gap in the bonnet (from inside the drivers seat, I see smoke shoot out from somewhere within the engine.. I was like f**k.. then I got around to the engine and tried to work out where the smoke was coming from.

At the time, I had the second pipe that connects to the plenum off (RB20DET, the one that runs from lower right corner of the engine bay, to the curvey elbow pipe before the plenum) - because I had to get the powersteering, as well as the vaccum hoses from the emissions box and, as well as the power steering and alternator/water pump belts.

The smoke seemed to be coming from the intake pipe that was still connected to the engine, and it smelt like a burning smell (rubber or plastic burning)...

Now the only thing that I can think of, is that maybe a little piece of rubber SOMEHOW got into the intake while the pipe was off, and became part of the combustion process, what I don't understand, is that if this was the case why would all the smoke be backfireing out through the intake, as oppposed to the exhaust.. So I really have no idea what the f**k it was.

I put the pipe and vaccum hoses back on for the remainder of the time when I was cleaning the pulley and cranking the engine, just incase something managed to get into the engine..

Upon reconnection the altternater/water pump belt, I started the engine and let it idle to see if everything was cool, It idled at 1,500RPM..

I then went to put the AC belt on and realized that it would NOT fit... So all this crap was completely for NOTHING!!!!!

then I put the powersteering back on with no problems.. So now, everything is back together, and the car idles at 1,100RPM, however I didn't give it much time to see if it would drop down to or so, and I haven't run it around the block yet (but I will).

Things seem to be OK at the moment, I was just wondering if maybe what happened with the smoke - if that was something really obvious to people, is there anything that I might have missed, should be doing should be checking... It may seem ok now, but what if it's something waiting to explode/breakdown/whatever when I'm sitting at the bottom of a hill?

Thanks
