PLEASE HELP!! TURBO WHINE!!!

[jktank]

So here is my problem. I had a y pipe leak, and I replaced the gaskets (didnt have money for B-pipes) Replaced those with the felpro gaskets. I had a slight turbo whine before I fixed this issue. After I put everything back together it whines twice as bad now. I have looked all over this forum and seen others have had this issue, but no solutions. all my turbo boots are free of holes and tears. When I had the turbo out the comp wheel was chipped up a little so I ordered a wicked wheel, but thats back ordered till the 26th and i need my truck so I put it back together until that comes in. The wheel had no play up down left or right. I have a 4 inch pipe and thats all the mods I currently have. I cannot figure out for the life of me what this whine is and I am now looking at gauges to see if I am low on boost or running my EGTS up. The reason I fixed the leak was I was getting a low boost code. Which I believe I am no longer getting, it hasnt came back up yet. MY truck is an 01 f350 quad cab short bed 7.3 no mods. Someone please help. Cannot afford to have anything melt down on me.

I would guess the excessive whine is the chipped vanes on your old wheel. I would also say your EGT's are prob ok given the stock setup. I would drive it unless I felt it was not running right. I bet you're low on boost a little due to the condition of the wheel, but nothing that would melt down.

If the oil is too old the turbo will sound bad. When was the oil last changed?
