Whistle sound

[bobloblaw]

i recently had my high pressure oil pump replaced as along with egr cooler now i hear a whistling noice that comes and goes its not the same noise as the turbo whistle but it sounds like a tea pot whistle. when i hear the whistle i just increase the rpm slightly it goes away when it gets up to running temp its not as bad .it will do it at idle also.truck is running fine but it is very annoying and quite loud

You may not have gotten the intake gasket seated properly or it had a cut damaged spot, there may be a cut/split in the air intake ducting,could be a lot of things haveing to do with the air induction system.

sounds like the turbo was not installed properly it is hard to hook up at back of engine
