Two things strike me here the '92 will be SPI single point injection and there for no ticking of the injectors. The '94 should be MPI multi point injected and have the ticking of the injectors so that count for some noise.

1994 has a sort of high pitched whine that is there all the time and increases when revved

Maybe just down to the timming belt being abit tight.

Other way round surely . I used to own an Spi 214 and the injector was quite noisy (constant ticking sound)

 

its probably the gearboxs and the different diffs
aqll the best.mark

 

It does it both in gear and declutched.

The noise from the gearbox is not part of the question here.

This is most likely belt noise.

I agree. It does seem more of a belt thing. If one of them is a bit too tight is it going to cause problems if i keep driving it? Which belt is the likely candidate?

Chris

P.S. Both cars are MPi, out of interest.

 

I would go with the cambelt being the noise maker. If you dont know the history of the car and when it was last changed it could be worth doing.

You could rule out the drive belts if you like by spraying them with ( cant remember what it called minds gone blank lets call it belt spray) somebody will put me right. DO NOT USE IT ON THE CAMBELT.

WD40?

Chris

 

Well it aint that sure its called belt dressing.

Barry

 

WD40 works too.
