Air leak

Hi guys replaced the cam shaft positioning sensor yesterday since then I can hear an intermittent air leak or something, sounds like when you pull the dipstick out while the engine is running kind of noise like a little squeal
 
Its normal if it make that sound only when dipstick/oil cap is open
Pretty sure everyone have it ( in these cars atleast )

He's saying it sounds 'like' that noise, not that that's what the noise is :smile:
 
It's comes and goes when cold. Replaced the camshaft sensor and cleaned some sensors so will receive check the work I did. Put new one rings on the breather valve just in case. What's the best way to find a fault like this
 
spray round with some brake cleaner...if theres a leak the engine revs will soon change if its on the induction side
