Well, I got the truck back today.... They said the water pump was bad and causing the driveway leaks and it was replaced with warranty and what was causing the unusual whirring... I guess it's good being at 90k miles now to have it changed out. They also wanted $350 to change out the lower overflow hose it's on order for $75 and will replace myself even though I see nothing wrong with it.
As per the exhaust leak they said they couldn't find anything I explained to them exactly where the leak was they said 1) no carbon tracks, no leaks... 2) it's not a part covered through warranty but for $400 they would change out both flanges if it made me feel better
So I brought it home drove it on the sidewalk halfway and let it cool for 2 hours sprayed it with PB catalyst on both sides and soaked for half an hour... Took a 15mm deep socket on the end of flex tip to the impact gun and loosened 3 of the 4 flange bolts the top of the driver side exhaust turbo was a pain and had to use a wrench.
I wiggled everything and sprayed some rust remover spray onto the connection and theng tightened up all 4 of bolts. Hooked up the positive side of my shop vac and blasted pressure back into these exhaust... Not a single bubble from either.
Pros; turbo whistle much quieter, no more rough idle at 2500 rpm, and gas smell in engine bay gone!
Cons; Ford didn't help at all on this one and it took about 3 beers deep on the very tight spaces to work on without removing anything.
