Whining noise from engine compartment

[2006PSDSD]

I don't know how to explain it, but this noise is driving me nuts! It sounds like a pump or something is going south on me, but I can't figure out which one. I hear the noise above 1000 rpm, and only after the coolant has hit operating temp. The oil temps vary with it though, but I suppose it could have something to do with that too. This all started after I installed my full BPD kit. No noises were heard before I tore it apart

Anybody else have an issue like this? What was done to fix it?

It is a hose routing issue. You are hearing the oil pump whine through your body. It is the hose from the block to the oil filter

I don't have any other way to route it, and I routed it the way the instructions told me to. I could only get it to go the one path . Is there another path to take?

I don't remember your name, but I know I've talked to you before, lol

Well that explains it, Nick! You can't read instructions...

Just kidding, buddy, but you saw how my hose was routed and I don't have any noises!

It does seem logical that the oil cooler thermostat would only open when the EOT was up to operating temp, allowing oil to flow through the hoses and cooler, causing the noise. Let us know what you find out.

There is also a droning noise, sounds like the fan clutch engaged but not as loud, and is between 1500 - 2000 RPM, and is the turbo pedestal.

I have the BPD kit, but not the whine. I do have the drone, so if I take it apart again, it will get the updated pedestal as suggested by FORD TSB's

I KNOW that my hose isn't going to route like yours due to the length. I think it may be a combination of both hoses after looking at them this morning. My #2 hose is routed between the AC accumulator and AC line, and I think that is part of the problem. I want to hear from Newman and go from there. I really prefer the way yours is routed

Never heard of an issue with the turbo pedistal, but now that you say that I remember something like a drone. Why would the BPD stuff compund that noise. The whine is at much lower RPM's (900-1300)

So you ADMIT that my hose is longer...

Nope! Just a MUCH different style!

The BPD doesn't compound the noise, it has to do with a weekend warrior like myself tearing apart his engine, and putting it back together.

6.0 Moan/Droan Between 1500-2000 RPM:
Engineering has investigated this condition and found the cause to be engine firing pulses causing the turbo mounts to vibrate/resonate. For trucks built through 9-29-03 install a revised turbo pedestal, P/N 3C3Z-6N639-BA. Trucks built after 9-29-03, install a turbo bracket A-brace, P/N 5C3Z-6N639-BA. If the draon is still present after installing the brace on trucks built from 9-30-03 through 1-17-05, replace the turbo pedestal with 5C3Z-6N639-AA. Ensure the droan is not caused by a bound exhaust system. Inspect for any damaged or broken exhaust hangers. Check the turbo downpipe by loosening the pipe at the top and bottom, checking its alignment and retightening. If the droan is still present, check the part number embossed on the turbo pedestal just below the turbo compressor outlet to the intercooler. If the number IS NOT 1846207C1, replace the pedestal with the above part. After replacement, or if the number IS 1846207C1, loosen the turbo inlet pipes and EGR cooler flange and neutralize by installing the components in this order: snug the flange between the LH and RH inlet pipes; torque the EGR cooler clamp to 53 in/lbs; torque the pedestal bolts to 23 ft/lbs; torque the turbo inlet clamp to 9 ft/lbs: snug the inlet pipes to manifolds. Ensure all components are properly aligned. Torque the flange between the LH and RH inlet pipes to 20 ft/lbs and the inlet pipes to the manifolds to 20 ft/lbs. Broadcast Message 0992, SSM 17530, TSB #04-9-4 & 05-19-12.

It could be the exhaust components, but I went through the up pipes, and downpipe, y-pipe a couple of times. All that's left for me is the turbo pedestal

Anyway..... I'm done hijacking the thread, back to whining and hoses instead of moans/drones and blowers...
