theres been a funny noise/bit like a whining noise when im driving could it be the turbo,there is no smoke coming out the back anyone know roughly
what it could be

 

and what turbo is on my car its a 92 4x4 standerd i dont understand t3 and t4 stuff

 

is it a siren type noise?your turbo will be a T3 on a standard sapp cossie fella

 

On boost or off m8 ?

 

no its not a siren noise m8 its like a dulish rattle type noise

 

on boost, but dosent do it all the time only started today when out driving the noise was on and off but its doing more often now if that makes sence m8

 

its a rattle noise!?if comin from the turbo that will be your waste get flap getting loose have u been losing boost?

not sure m8 normally i can hear the whistle of the turbo but when the rattle/noise comes on it doesent have the bite as normal if that helps sorry dont know out about the engine

 

sounds like u waste gate flap is at fault which is a internal part of your turbo,or a cheaper option it may be your actuator getting weak and not being able to hold tight against your wastegate rod?

il get it checked thankyou for your help m8 getting recondiditioned is that worth getting done or saving and buying new 1

 

well if it aint your actuator and it is your turbo just your one rebuilt again fella will just be as good as a brand new one

 

I would try an actuator first, as you will need one anyway if buggered if not make a nice spare.
Is there wear on the spindle that goes through the turbine housing ?
Physically grab(COLD ENGINE) the arm/spindle on which the rod from the actuator goes onto and see if it has any sideways play or up down movement.
The spindle part of this arm that passes through the turbine(exhaust) housing wears very badly, this causes the valve inside the housing which is just a round flat piece of metal that seals against a hole inside NOT to seal properly and so you lose boost, they TILT and normally crack the housing seat where they(valve) sits as well, but this is NOT necessarily bad, some can still be ok with this.
If wear is not too bad some can be repaired, if not it will need a new TURBINE housing, around £150 for T3.
If going to have it rebuilt, may as well go 360 and step gap at same time for a little extra.
The std bearing is a ring of 270 degree's but this can be changed for much better 360 degree one, essential if tuning though even std will not be very good with 270 bearing.
Step gap seal will help stop oil loss through turbo, by about 80/90%.

good advice from tabetha

only one prob that i could see....
you ve spelt G.B Turbo Solutions wrong
see here

I am sure that you do a fine job GB, but can only really recommend people from personal experience.
I am sure however that there are others on here who can recommend you.

right been out in the car tonight the noise sounds a bit more like a belt slipping noise, the noise is not spinning as fast as the turbo would, i turned all the lights on the heaters etc and i am getting a whining noise from the alternator and goes off when lights are turned off, has anyone come across this before and is this more than likely my problem and thankyou 4 your help

 

How bad is the winning noise cause im sure they make a noise when u have heaters n lights on cause the alternator is under load.If its bad it might b the bearings in the alternator. You will need a new alternator. Thats if u carnt get it re-conditioned.

 

its quite loud would it make a noise when driving without the lights on if the bearings are nackerd

 

If Iwere you just as a precaution I would disconnect the fan belts, for the alternator to make sure it is that, other wise it is most likely your TIMING BELT TENSIONER, and this is very bad news.
If it is the alternator, they are relatively cheap to do, but recon is better bet as housings can crack when extracting bearings even with heating them, if they are tight which they can often be.

why is it a nightmare if its the tensioner

 

cos if your timing belt snaps or isnt tensiond properly it can equal major damage

 

If I had a whining tensioner I would not even start it!!
It is just not worth the risk, as said if it decides to seize, it will first melt your belt against the pulley, then snap then bend your valves, possibly even crack your pistons.
Tensioners are easy to do, 10 minutes maximum, and not too expensive, about £35/£45, don't even need to take belt off to do one.
Just tension to correct tightness, tighten to 45NM(locknut) job done.
If you were anywhere near Narfork I would do it for you FOC.

had the car today at my m8s garage checked the belts and tensioner everything seems fine he said and the alternator is ok the noise is a whistle noise quite deepish im not loosing any boost or smoke out the back what could it be

 

That's just paranoid mate, it only cost me £1350 when my cambelt failed

 

have you checked for play in the turbine shaft?
mine was so worn it was moving around left right,back and forth. and the blades were catching off the housing making a loud whine.there was also no smoke coming from my car either.
my money is on it being your turbo m8
