Hello guys, sorry in advance if this is the wrong section to post this Question in, if it is, could a Mod' please move it to the correct section, cheers!
Ok so today I went to do my usual weekly checks on my engine, and as I started her up (MK4 1.6 8v astra club - Dont know the engine X code sorry), I noticed a rattling/ticking noise from within the engine bay. I more or less located by ear that the noise was coming from near the air filter / cam belt / spark plug section, but everytime I rev my engine it can be heard. Its not an overly loud rattle, but it's never been there before.
Have checked the spark plugs, all tight, checked for anything rattling in my engine bay, strut brace, loose cables/ harnesses, and all seems ok!
It sounds like a ticking/rattling noise, it's not really loud, but its annoying me now since ive never heard it before!
Many thanks in advance to anyone who can offer me any suggestion as to what it may or could be!
