call me daft but on motorway other day i noticed a faint noise i havent heard before on car it was like a whine noise off turbo as it came on boost only lasted 3/4 secs not noticed it before any ideas?? could it be the bearings in turbo by the way there is no smoke and it spools all the way to 21psi then holds at 17psi its a sti type r v3 also dont know if this has anything to do with it but the spring in my dump valve is really weak and lets out gas really easily??? could this be the cause of my new noise or is the turbo on its way out?? the turbo is a ihi vf23 roller bearing turbo. HELP PLEASE!!! ONLY TECKIES NEED APPLY!!!!!!!!
