Hey mate,
It started to go away again but 'sometimes' if I'm pulled up near a wall or another car at the lights I can faintly hear it. But it's nowhere near a loud as when the oil was first changed.
As a sidenote Redline are shipping the bearings and studs over at the moment so hopefully by Friday week that will be all finished up and we'll see if that impacts the noise. The irony is now that the random tick is gone there is another ticking happening!
///M Power-Belgium had a listen and seems to think the same as me that I have an exhaust leak. It's one hell of a tick noise but it's only audible on the drivers side, can't hear it on the passenger side.
Once she's out of surgery I'll let you know
