Wind and Whislte Result + 5th gear?

Well for quite a while iv had a whirring noise,a whistle and also a sound what i can only diagnose as air escaping from behind the engine...The Portuguese Mechanic has diagnosed it as the aux belt tensioner that controls the air con! he showed me and it is definatly coming from that area but does that sound about right?he reckoned aux belt and tensioners would fix it...He also removed the belt and the noise stopped...

Second problem i have is a grumble in 5th gear,now i have posted this on here before and some people have said 5th gear needs replacing\rebuilding,but iv also read that someone has the same problem and some people have said it could also be driveshaft or engine,gearbox mounts.......

My 5th gear symptoms are: A constant knock\grumble(not wheel bearing,kinda like someone knocking on your door knock!!) when in 5th but usually only...if going around a corner(either way) or when i lift off the doesnt do it when i accelerate hard in a straight line but if i accelerate out of a corner it does! there are ways of not making it knock!....The Gear stick does have some vibration in 5th,more so than in other gears...

So.what do you guys think? i just wanted to know again as the other guys thread mentioned the above posibilities and i dont wanna get ripped off by a Portuguese mechanic!!

Re: Wind and Whislte Result + 5th gear?

He's right, it's the tensioner. Easy diy change if you fancy it. Kind of proved it by removing the belt and noise stopping, i.e worn bearing not turning without belt= no noise. If you want confirmation stick a screwdriver or similar on the tensioner body (not the moving part) and your ear on the other end, amplification when compared to a smooth running part is obvious.

Don't do this if you're the sort who's likely to get long hair etc caught up in moving parts....

I think your gearbox needs to be taken out and examined before telling something

Old thread but....having just bought this car I can say that the noise was/is the power steering pump. Easy fix. The 5th gear issue is the retaining nut on that gear working loose (we think!) doing it today.
