2002 Ford F250 FX4 off road 7.3 Noise coming from turbo or engine

Eagleeye said:

I UPGRADED my HPOP hoses and added the cross hose because I had a leak, replaced O-Ring and worm clamp on turbo, went for test drive engine stopped and wouldn't start, got towed with a rope back to the house, had to top off the power steering fluid because I lost fluid while getting towed, found out the the fuel pump relay went out, bypass fuel pump relay, Now I hear this very annoying noise coming from the engine only when driving whenever the the TURBO spool to 5.5 psi and above, gradually gets louder.

most folks create a youtube account and upload the video if it helps. The reason I ask if a buzzing electric noise vs a mechanical grinding sound, vs a mechanical squeal etc they all mean different things. Also what hoses for the hpop lines did you get? The cncfab llc brand with steel braided lines or the soft rubbery type hoses off ebay? The soft rubber type hoses will leak sooner than later so im hoping you just spent the $137 for the cncfab llc kit. They are the only true aftermarket kit that works and is affordable. Also some kits tell you to remove the little metal plate and ball fitting and some dont etc so wanting to get as much info as we can to help more.

If the turbo is making a whine noise it could be the clamp is not seated correctly leading to higher egts, lower boost and sometimes a whooshing air rush sound.

Just gonna give you the cold hard truth those will fail in short order.... This is the kit you will be buying soon. CNC Fabrication Early 99-03 7.3L Replacement HPOP lines - 7.3-SD-HPOP-LK

Again don't want to bash your hard work but those EXACT ebay lines will fail you sooner than later. They just can't take the intense cycles from the hpop. But once the noise is clarified we can address the hose issue etc

Any possibility that's the PS pump with some air in still in the fluid? (I mean, it Does almost sound like it could be turbo related, hard to tell without being there... )

Can you get it to change with Load on the pump, keep it in 1st, so you're going too fast, and make hard turns maybe?
