Only used to do it when it was cold, after some sideways action on limestone 3/4months ago it started making this noise, it happens only under load.
It's not an exhaust leak or pinging.
It's hard to make this noise stand out above engine revs and clutch fan noise and when I've taken it for test drive with mechanics they say it's normal when IT NEVER USED TO DO IT.
It does my head in every time I drive it, cause I know some thing's wrong but can't find it.
It's more predominant when driving next to concrete barriers which bounce the sound back.
I'm hoping it can be heard on the dyno under load so it can be fixed.
Before I go to dyno I need to finish all the valve clearances, check timing chain stretch, check vacuum hoses and PCV valve.
I hope the above fix it so I don't have to take this further,
I'm going to make a recording of the noise tomorrow.
Thanks
