Hey guys I recently bought a 2006 Mazda 3 GT. The car runs great, but the only problem is it a ticking noise is coming from the engine. Ive taken in it to many mechanics and some have suggested that its just the driving chain which is causing the noise, and recommended that I put ticker oil in the engine. Ive done that and the noise is still there. I was wondering has any one else experienced the same problem? And what can i do to fix it cause its quite annoying
