ok I ended up taking the entire pipe out which goes into the well of the car and now tried to take it off the circle o ring thing off and the tools I have are for lighter work ie to take the MAF off so buggered at the min althou I have it in my hand
sorry the end decided to go down and couldnt reply. After using brain power I have managed to fit the new pipe back on and its all working fine - much more pull as well!
