Clicking sound
28. Aug 2011 at 14:26

Afternoon all.

My mig has decided to develop a problem today and I'm hoping somebody can point me in the right direction.

When I started the car up earlier I noticed a clicking sound coming from under the bonnnet.
It's clicking in time with the turnover of the engine.

After idling for a minute when first switched on my rev counter always drops slightly and you can hear the turnover slow down.
Well the clicking sound slows down with it and when you press the accelerator it speeds up.

The sound is there when idle and also there when driving.
It increases and decreases with the speed I'm travelling.

Help required plese guys Undecided

Back to top	Do you break V6's as often as TheBoy? Then you need tunnie's towing services, recovery costs are just the humiliation of being towed by 2/3's of an engine IP Logged

Aug 2011 at 19:06 A couple of people have mentioned the exaust manifold so i'm going to remove the heat shield and inspect it as suggested by Tunnie. Will do it within the next few days and post the results on here. If it is that I hope it's not too bloody expensive a fix

Aug 2011 at 19:38 After removal of my heat shield my manifold was cracked across the top had it welded and the clicking continued thats when we found out about the stud missing from the manifold its self. Some say you cant have them welded but this myth is untrue.

Unlikley due to the fact the tick increases and decreases in time with the engine revs
