Thought this may be of interest...
Monday - I noticed , engine pitch had changed, sounded to me like alternator was on its way out, couldn't see anything, informed mechanics at my place couldn't see anything.
Tuesday - on way to work, noticed noise was more pronounced, like alternator was about to fail, eventually slight rattle, heard the sound reverberating off cars as I passed, knew it was mine
. I was in queuing traffic, rattle became louder, then battery warning light came on, eventually sounded like my exhaust had dropped off and rattling, at this point I cut the engine off, fortunately I rolled into a junction to a halt. 
Had a look in engine bay smelled slight like burnt plastic, noticed one of the pulley cogs looked like it was at an angle, AA man came checked it out had a feel, said he thought the idler pulley had collapsed. So decided to take it to the garage...seconds away from the end here's what we found...








Fortunately the engine is safe, it was seconds away from being destroyed a very close call. From what I understand here is what happened. Bare in mind I had my cambelt changed about 18months ago by Peter Smith Lotus during a costly C-service. As you can see it appears the bolt hasn't had any lock tight put onto it during the timing belt change (very worrying, considering this was done by a "former" Lotus Garage). It appears because no lock tight was put on it, its allowed the bolt to come out over 18months, this has forced out causing the key to shear off, pushing out causing the pulley to slack, causing the alternator to fail (no power being charged to battery so light comes on), then pulley completely collapses (loud noise), forcing the cam belt to edge out, which slices the bottom cam cover in half and forces it off completely till I turned engine off with only a few mm left of the cam belt still on. Fortunately the timing mechanism was affected and this was a very close call... its good to be paranoid about sounds and if in doubt, kill the engine. Thankfully its all repaired, I have to thank mike at MGW racing for getting me back onto the road quick as its my day to day car.
Very lucky, really really angry though with the fact my last Cservice with PS lotus appears to have been a cowboy job, feel free to comment.

Vitaly Petrov post Indian GP qualifying interview
At the end of Q1 today, Vitaly stood head and shoulders above the rest of the field after posting a time of 1min 26.181secs. In Q2, however, he was unable to improve on this time and finished 11th fastest. As a result of his five place penalty -- following an incident at the Korean GP -- he will begin tomorrow's Indian Grand Prix in P16. We caught up with him tonight to get his reaction to event.
