Bad Turbo Whistle-Please Help
Hi, I have a 06 f-350. Just today i noticed a horrible whistle from my turbo. I've been doing some research but just can't find the problem so thought I would ask. It was doing it at low throttle and no throttle. I opened the hood and could hear it really loud. I unpluged the wire to the turbo and it stopped completely. So it must be something to do with the turbo. I do have an egr delete and have done arp studs and black onyx head gaskets if any of that would help. Thanks in advance for the help. I know i'll get the answer soon because everyone on here is super awesome. Thanks again!!!
