This morning I was driving to work and about 100m from the school gate the car started making loud banging noises. I have been around enough race cars to know what a broken conrod sounds like and that was very similar to what I was hearing. I got a workmate to tow me into the school carpark and spent the day organising a new motor and tow truck to get the car home in between classes. My old bloke came around tonight to see what I had done. I started the car .... bang, bang, bang turned it off quickly. We opened the bonnet and started it again and the noise was gone but the motor was rough. The old man said one of the spark plugs was jumping up and down with it's lead and must have been smacking into the bonnet
. A quick check showed it had worked loose and bashed the crap out of the top of the thread going into the cylinder head. I managed to carefully insert a tap and clean it up replacing the plug with a new one and hey presto all was well
. I just hope I have not removed too much metal but will be carrying a plug socket around and checking frequently. I really hate cars.
