Hi, I've been getting conflicting answers about this.. There is a noticeable regular clicking/ticking noise under the bonnet on the driver's side of 2004 Mazda 3, some people are saying this is normal with Mazda VVT, and others are saying this is the sign of a major problem with the timing chain tensioner and could damage the engine if not addressed. Can any Mazda owners/specialists advise me? cheers
