Ive noticed recently a tapping noise coming from my engine, even after 15/20 mins of driving so im starting to worry as I cant afford a new engine atm (or a car to replace it :\) was just wondering if its series or just the colder weather we have at the moment as someone said it could be the camshaft or something. The engines a 1996 1.2 D7F (DIET) Engine. Any help/advice needed as plan to do about 800miles driving this week
