    does it do it when the engine is cold?does it go when the engine warms up after about 5 mins if so they are the same syptoms ive got. have you changed the cambelt and rollers could be them or it could be the purge valve that sits behind the air filter box, it could also be a sticky tappet im having mine looked at, at the weekend will let you know what we find if anything.im not a mechanic the above are all things people have said my noise could be.

    mine does the same. ever so slight squeak that isnt ment to be there. mien most of the time goes wen the engine has been runin for about 10 mins. but sometimes can stay wen just ticking over. i took it to my garage who said it could be a few things to do with the fan belt. like bearings or tensioners. my dad said the same thing too.

    anyway my car is in the garage untill later tonight getting that and a ticking sound checked so if they spot anything i will let you know
