The saga continues I decided to make a start taking off ever hose & checking them.
When I removed the hose connecting the airbox to the throttle body it showed that the fibreglass had deteriorated & broken apart where the jubilee clip fits.

I hope that is the culprit and will get a fibreglass repair kit tomorrow to work on it.
Also the plastic T piece into this hose for the breathers Heinz referred to was brittle and broke apart so I need a new one of those as well. I 'll get it in copper.
