I'm going to check a few things out first take one bit off at a time then the clutch inspection plate just I was thinking what If something fell in there? Look at everything before taking the engine to bits it just Dosnt seem right that the engine would be fine one minute and not the next. Sadly it's all down to money now I thought spending all the money on the extras was the way to go and then the knocking happend.. I hope it's something simple. Iv booked next week off. I know the mrs won't be happy but tough. so if I haven't found out by monday I will take it apart and learn myself. Got nothing to lose..
