    rattling sound when accelerating

    Well, i noticed on my astra (since it is summer and windows are down) that when i accelerate i hear some rattling noise, that noise cant be heard if it is in idle even when i keep throtle it cant be heard, only when i drive my car and i keep throtle (and in some gear) , sound that i hear is like this one on yt clip ( http://www.youtube.com/watch?v=xgJtLDGg8yE only eliminate engine sound, the rest is what i hear with my engine sound), sound from 36'th second, maybe cambelt tensioner? Place where i did service 2 weaks ago are not very profesionals. So what could this be, is it dangerous?

    If its a mk4 i would try the alternator belt tensioner. I had a rattle like that for ages then i decided to change that and it went straight away. only cost me 12 quid lol. 5 10 minute job.

    I drove it for about a year or so and it wasnt a problem so no need to worry if it is that that needs replacing. worth doing it though cuz its only 12 quid od. Let me know if it was that in the end. cheers.
