thanks, i will be popping in tomorrow
ive had a closer look today, it is coming round the top of the air intake area where it is joined to the engine, makes a normal jazz noise when running and the noise seems to be a valve, relay or something inside there somewhere reseting itself, it does sound like it could be normal but just a bit loud.
i will add a couple of videos when i get home later.
also im sure i didnt notice this on the test run on this exact car as its a pre reg but had only 16 miles on the clock.
