Engine noise - rattly squeek/squeal

Postby owain1 » Sun Jan 02, 2011 1:06 pm

I've only noticed this happening recently, but it could be that I can't normally hear it when the radio/fan is on.

There seems to be some sort of rattly/squealing noise coming from the enging, but only when it's in gear/being driven.
If I rev the car up in neutral it doesn't seem to make a noise at all, neither does it make a noise if I dip the clutch+rev it whilst I'm driving.

The first time I heard it I just assumed it would be a belt that needed tightening/replacing, but does anyone have any idea what it could be? Would most belts still squeak when the car was in neutral with the engine running?

I know I've not given you much to go on, but I don't know how else to describe it!

Thanks :mrgreen:

Check your oil level, if it is low it can cause rattling

As I say, check your oil level first, it normally us that simple, usually the issue when I get a rattle

Sorry I missed your post, the oil level is fine.

I'll see whether it's still happening tomorrow, I didn't notice is as much on the way home, so it seems to be when it's cold.

On my gen2 the power steering belt squealed but only when driving. If you turn the wheel it puts strain on the belt (full lock is best ;) ) and can make it squeal.

may be the other belt, under the powersteering that drives the waterpump and alternator, pretty easy to adjust, slacken off the retainer bolt, then theres a threaded bar with a slider on it, just tighten it and you'll notice the alternator mooving, and the belt tightening.
