Hi all,
I need help. My 80 Series 1 HZ Diesel with turbo has develop a 'whirring' sound in the engine bay - sounds similar to the old style hand beaters whizzing. It sounds as if it is coming from the passenger side of the motor and is starting to worry me.
It is only there when I am driving - can't hear at idle and goes once the revs pass 2100.
At first I thought it might have been the turbines in the turbo - but the turbo is on the drivers side and I have had it checked and it's okay.
Can not recall exactly when it started but has been there for some weeks. I have recently replaced the fuel pump but it was there before this was done.
I have also in the past few week done the following things myself - an oil change complete with new oil filter, changed the fuel filter and air filter - just wondering if I mightn't have tightened something - but I have double checked.
Any ideas??

How about the bushes in the alternator and bearings in either the aircon clutch or the aircon idle.
I would also rev it up in neutral and see what noise the PS pump makes especially when turning the wheel
The vac pump is also over that side too.
Check your belts also.
Water pump
When looking for engine bay noise I spray belt conditioner on the belts which makes them dead quiet or a few moments and gives you a chance to really hear the engine and its periphereals

Karl, I think
Ross has covered most of the options. I'd be putting my money on power steering pump either low on fluid or internal problems...just because thats more common than the other things. Good luck

Inside the reservoir there is a bronze sintered filter. As they get old they get blocked and cause cavitation which givesyou the noise. You can remove the top and clean with petrol and reseal. Usually stops the noise.

As said already, I'd go for the PS pump. I had weird noises from the engine bay of my 80 series for a couple of weeks and had trouble identifying the source. When the PS stopped working and I replaced the pump - no more noise!

Thanks all. I was thinking that it may have had something to do with the power steering as the resivour has develope a small leak over time - I did top it up a couple of weeks ago but will check it again.
Thanks.

Hi Karl, try very carefully placing a length of wood about 2 feet or so on each of your anncillaries (w/pump, alt, a/cond etc ) and the idlers with the motor running and if there is a problem the wood will sing (no,i'm not joking).Place your thumb over the end and put your ear near the wood. If you use this method be very careful!!!
I had a similar problem with my 80 and everybody told me it was "the air cond, the w/pump, na its your alternator mate" my dad told me this method and it was the bearing in my air cond tensioner pulley.Just make sure before you start the motor you work out how you can get the wood or screw driver on to the bit you want to check.
cheers geoff
