R wagon Posted September 24, 2008 Report Share Posted September 24, 2008 Hey guys, recently Ive noticed a whistle like noise coming from my engine whenever im on the throttle. It seems like it is the loudest when the car is cold. The noise isnt very loud but loud enough to be heard from the inside of the car with the windows down. Anyone know what this might be? Thanks.Ben Link to comment Share on other sites More sharing options...

lookforjoe Posted September 24, 2008 Report Share Posted September 24, 2008 How's your fuel consumption since it began?I'd check all your vaccum lines & intercooler plumbing.Also, does the car still boost normally (same levels?) Link to comment Share on other sites More sharing options...
randomdude Posted September 24, 2008 Report Share Posted September 24, 2008 sounds like a good old fashioned turbo to me. :lol: Link to comment Share on other sites More sharing options...
Jaxx Posted September 24, 2008 Report Share Posted September 24, 2008 as long as it isn't howling and smoking you should be okay. double check vac lines and make sure everything is together. Link to comment Share on other sites More sharing options...

Dan A Posted September 25, 2008 Report Share Posted September 25, 2008 My turbo is noticeably louder until it warms. Of course I'm only under light throttle until it warms up, but I can still tell. I'm thinking/hoping it's normal. Link to comment Share on other sites More sharing options...
Medicman55 Posted September 25, 2008 Report Share Posted September 25, 2008 Same thing here. Now that you mention it, I never really thought anything of it, I just thought it was a Volvo thing. Link to comment Share on other sites More sharing options...
WhiteT5 Posted September 25, 2008 Report Share Posted September 25, 2008 They all do it. No harm seems to come from it. Link to comment Share on other sites More sharing options...
