gavin.starr Posted July 25, 2011 Share Posted July 25, 2011 I have been developing an engine tick over the last 2 months or so. Its really quite hard to describe. It has a noise like an exhaust blowing but its got a tick to it like it could be the cam or engine related. The thing is you cant hear it in the car, its only when you over take a car or go down a road with parked cars or a wall with the windows down, the noise level stays constant but it increases with the revs of the engine when driving. I know that one of my turbos has the notorious hairline crack in it so i dont know if it could be gas escaping from that or not? Im pretty stumped Can any one help?

Ian C Posted July 25, 2011 Share Posted July 25, 2011 I uploaded a couple of WAVs regarding my engine tick recently, it's in a thread in tech somewhere. Have a listen and see if it's the same. Quote Link to comment Share on other sites More sharing options...
gavin.starr Posted July 26, 2011 Author Share Posted July 26, 2011 A mate of mine said it sounds more like a crack in the exhaust manifold, rather than a tick. It doesnt sound like anything is tapping together, its more like a venting of air in bursts. Like it could be a loose sparky (but its not) its on of these types of noises that has to be heard not described. But i cant capture it. Really annoying Quote Link to comment Share on other sites More sharing options...
Iky Posted July 27, 2011 Share Posted July 27, 2011 I think I have this as well. Is it like a fluttering noise from behind the central heater vent? It's hard to hear unless its absolutely quiet. I asked M-life to have a check but he coudn't hear it. Im going to see him again tomorrow. Hopefully we can trace it. I'm hoping for it to be a loose heatshield or something because I can hear something underneath which seems co-related. Quote Link to comment Share on other sites More sharing options...
gavin.starr Posted July 27, 2011 Author Share Posted July 27, 2011 Mine only ever does it when the engine is under load. if its stationary and you rev it there is absolutely nothing, bus as soon as you select a gear and drive it comes online. some one really has to hear it to see what im on about.

Iky Posted July 27, 2011 Share Posted July 27, 2011 You could get M-life to have a look at it. He's in Oldham so not too far. Quote Link to comment Share on other sites More sharing options...
