Hey all. Put about 15 000km on my truck so far since I purchased it (189 000km in total right now). Only had it since mid summer, so trying to get used to some of it's winter quirks. Right now there are three things that are concerning me.
First is that the turbo has started sounding different, way different. When it gets between certain pressures, say 8 and 16PSI of boost, it'll go from it's nice usual wirring sound to sounding like a turbine thats ever so slightly rubbing metal on metal. I get it is cold out so it takes time for oil to warm up and get around, but this happens regardless of how warm the engine is.
Second issue is the amount of exaust coming out. Right now it's floating around the -17C/0F mark. I get the whole moisture in exaust = large exaust ploom. But until my engine really warms up there is a stupid amount of steam coming out the back. If I floor it enough comes out that no one immediately behind me or passing me in the opposite direction is able to see the road. Thus far I haven't noticed a loss in coolant, so I don't know what else it could be, if it's even an issue?
Third one is another very new sound. At first I thought it was the turbo again, but it doesn't correlate with anything else. Regardless of throttle application, engine rpm, gear, turbo boost, etc, the engine produces a very high pitched whistle that manages to drown everything else out. It isn't a constant sound, it happens intermittently and doesn't last long when it does, but it is concerning.
Anyways, I'm wondering if it'd be prudent to take the turbo out, rip it apart, clean it, inspect it, and throw it back in? If so, where would I be able to find a how-to guide?
Your white exhaust vapor may just be normal. Do you use a block heater? High pitch whistle u describe as intermittant & rpms don't matter, hmm? You didn't say, so assume you notice no loss of power at anytime? Look for updates. Good luck!

Awesome, thanks for the link. There is no real loss of power except when the motor is cold. Shifts a bit rough too. But from what I know that is normal.
Does the high pitched whistle come and go with boost pressure? If so you have a leak on the pressure side such as a hole in a boot or in the intercooler, etc.
Large "steam" plume could mean coolant leaking from the EGR cooler into the exhaust.

Truck was said to have been "bulletproofed" by previous owner. But not everything was done. I had the old mechanic give me a list of what was/wasn't done, but I have since missplaced it. However I believe the EGR delete was part of this. If this is the case, could this still occur, and how do I verify the delete and that the cause of the plume may be a leak?
If it's a full delete then the EGR cooler (long square thingy in the engine valley next to the passanger side of the intake manifold) will be gone. If it's a sneeky delete then the EGR cooler will still be in place but the exhaust inlet and outlet will be capped and welded up. (still possible to have a small leak from the cooler if the welding was crappy. There are "Bullet Proof" EGR coolers that have had the OEM internals removed and replaced with tubes which are pretty much leak proof.
Well there is and EGR cooler in there. What should I look for and where to see if it is stock or a bulletproofed one.
Also, a week ago I grabbed a mechanically inclined friend to have look at turbo. Took the intake off, tried shaking it around, spun it, ran engine, etc. The thing seemed fine. So we threw the air intake system back on. He figured a pinhole in the exaust. Side question from that - is the plastic cap on the front of the air filter really necessary?
Anyways, squealing went away for a day and a half, then came back. At first quiet and intermittent like before, now it's loud and constant. Granted I've been driving it lots. No change in performance, just that incredibly annoying noise.
Speaking of which, we recorded it! From startup to when squealing starts. Squealing took a little bit to happen today, so just skip to 2:50. Turn your volume down too. We recorded with the hood open, but didn't know how to post a audio file, so we just attached it to a picture of the truck to it after recording -
Sounds to me like a fan clutch or serpentine belt slipping.

When the y pipes start to split and the hole is very small, they whistle. As they get bigger it will start to hiss. Common symptoms are loss in power/boost and exhaust smell in the cab. Don't know about the moisture.

While others have complained of smelling fuel in the cab, I haven't noticed any exhaust smell.
The dealerships are closed, but I stopped in to see an off-duty ford mechanic I know. He figures it is the turbo bearings going, and that it is caused by my HPOP ****ting the bed. His rational is that at idle there isn't enough pressure from the HPOP anymore to lubricate everything at idle, but at higher RPM and higher engine pressure, the oil pressure is high enough to lubricate the bearings. Another symptom of this that is presence is a very rough cold start. I just assumed it was because of the cold, but apparently it shouldn't be as much of an issue as mine has been.
Anyways, ugg... How difficult would this **** be to fix? I'm due for an oil change shortly, so I'll get that done before I head back to Alberta. Get a firm diagnosis then as well.
The theory would be plausible if the turbo was lubricated by the hpop....but it's not. Everything in the engine is lunricated by the low pressure oil pump. The high pressure oil pump is only used for injector operation. And plus, if ur turbo bearings were starved of oil to the point where they squeal, it would have exploded pretty much instantly.
