2.0 DISI petrol ticking noise at idle
« on: November 28, 2015, 08:20:02 pm »
Hi guys,

I don't know if this is normal as this is my first petrol Mazda, but I can hear some ticking noise from the engine once is warm and at idle speed. If I touch the throttle a tiny bit it goes away until the revs drop back to that 600ish warm idle. This engine is direct fuel injection could it be that noise?
Has anyone else experienced this? I have 15000 miles on the clock and got the car a month ago from a main dealer who serviced it before I bought it.
It is a 11 plate 2.0 Petrol.

Thanks

Given that it is the same engine as the Mazda3 2.0  I'd venture to say Butterfly Valves.
Look at life through the windscreen, not the rearview mirror.

Okay? Is that an issue? Or is that normal? It is a constant tickticktick noise at idling.

Yup. That's the one.   You are still a member on the 3 forum. There is plenty of information there regarding this.

And the in 2010 they updated the engine. It is a newer type DISI, not questioning you, don't take me wrong, but if there was an issue with the butterfly valve I suppose I would hear it all the time.
But could be wrong. I ll keep an eye on it. It has 3 years RAC platinum warranty.
What is the worst that can happen if this is really the butterfly valve?

I found this on Wikipedia.

The plastic intake manifold on early versions of the 1.8 and 2.0 has a major fault due to poor-quality materials. The manifold has swirlplates mounted on a square shaft at the aperture where it mounts to the cylinder head. Early 4-cylinder Duratec engines can be ruined when the swirlplates break off and enter a cylinder. Most cases are of single swirlplates but also the shaft can wear and break. Early signs of this fault are evidenced by a ticking noise emanating from the front of the engine. This can occur as early as 25K miles, with failure typically occurring after about 90K miles. (more details)

Applications:

2007–2010 Ford C-Max
2004– Ford EcoSport
2003–2011 Ford Focus
2000–2007 Ford Mondeo
2010–2012 Ford Transit Connect
2004–2005 Mazda Axela/Mazda3
2002–2008 Mazda6 for Europe
2006–2007 Mazda Premacy/Mazda5
2006–2015 Mazda MX-5

Has anyone else have similar noise? Or am I the only one? I asked my mechanic and he said it is a normal noise.
