Well, a few weeks ago, i noticed a ticking noise, turned out one of the studs that holds the extractors on had snapped off in the head, and there was a gap between the extractors and head, and some exhaust gas was escaping and making the ticking. So we took the extractor off and got a right angled drill chuck to try drill the stud and then get and easy out on to it, but of course it was high tensile! so got a different drill bit, and finally got a hole started, but because the aircon compressor was in the way, the hole ended up off centre. So after a lot of thinking and fighting with dad, we decided to unbolt the engine, jack it up in the car with everything still attached, take the aircon compressor off and try drill the stud out, but we couldn't get a hole started in the centre. next idea was to get an old exhaust manifold off of a vs, make a template of all the bolt holes on a bit of flat, and make the hole for the broken stud the size of the drill bit so it would drill in the centre of the stud. Luckily this finally worked. so after we got a hole in there, we used a reverse drill bit and after about 10 minutes of drilling in reverse it just popped out.
whilst we had it all off we noticed that where the exhaust was blowing out, it was right on to the bottom radiator hose, so a new one of them. also we noticed the water pump was about to let go, so a new one of them as well. also we found that 2 of the idler pulleys had crook bearings, so replaced them.
So what should have been a 2 minute job just to screw a new stud in, worked out to take about 10 hours. But it didn't end there. After driving it around for a bit, it was starting to miss and play up. This turned out to be the coil, which also had the exhaust blowing on to it, but luckily that was an easy fix. A whole lot of ####ing around, for one little stud :/
