noise.?

[rob turbo]

got a strange one ....

it's a screaching sort of, winding metalic one. on boost/acceleration it appears to sound like it's winding faster, then just go's a kind of screahing noise.. has gotten a lot worse & has developed more over time. no smoke & boosts ok, checked all the pipes, no leaking.. im told its the turbo possibly it'self...??

any ideas guys please

cheers

Turbo gaskets probably

it's not blowing at all though..

I'm with martin on this one, had the same sort of noise on Slimreapers old S14, it was the turbo to manifold gasket that we had blown to bits. Made the oddest noise when it came on boost, thought it was the turbo eating itself at first!

it does the same noise from manifold to head as well.

hhmm, thanks for your inputs guys, however ive just had the manifold gasket done + checked the seals in around the turbo.. do's not sound like it's from the engine realey, will do it stood still & rev it.! a weird one this, driving me crackers.!

any more suggestions..?>

cheers

Was it doing it before you had that work done?

[rob turbo]

all ok, we had to take the inlet manifold off as there was a water leak from one of the pipes that, like to cause you untold greif to get to. we nailed it back together using instant gasket... hmm that worked.!

so after i spat that out, along with all the water, i took it to my tuners, he put the head gasket back & nailed it all together again, then this noise started.. a small murmurr, now a good wacker of one..

just a screach as it's boosting.. no loss of power, no visable adverse effects..

just this noise, painfull it is.
