yeah mate he re-used them after he sprayed the pipes aswell lol, if it was me i would replace all the gaskets that have been messed with all on the turbo side and on the manifold/throttlebody side, if it still whistles then you know it cant be a gasket, but the pipes have been checked and new turbo,

Hence why if he doesn't check the gasket I won't be giving advice anymore. I've been helping him over pm and first suggested boost leak test the hoses. Then check induction side. All that was fine so said gasket. Since then, he's rechecked everything but.

hi guys havent been on here today.

 

i will get new gaskets lol

 

i will get intake manifold gasket, idle control gasket, throttle body gasket.

 

on the turbo side: the ones on the intake pipes.

 

also gone test the fmic on its own incase that got damaged somehow when was removed.

 

only re used as read several people on here did.

 

going to do another boost leak test on the turbo side to see if can pin point which one is.

any updates mate?

 

sorry, only got round to doing another boost test yesterday,

 

tested the turbo side this time, still coudnt hear where its coming from.

 

going to get gaskets next and then hope for the best.

 

 

wierd though, as i set the compressor to 20PSI yesterday and youd think it would make the whistling sound somewhere, but nothing :(
