slight metalic sounds?
Hi Ford Fans,
I have a question. What would a turbo sound like and act like if it were to start having problems? Would it be a constant sound across the entire rev range or could it come up at a specific rpm? Would boost be unaffected?
The sound I have comes in around 1500 rpm when making boost ( 5-10psi) and seems to linger during deceleration ( below 30 km) I haven't looked yet but my first spot will be the cold side of the turbo. The truck makes the sound as rpms build not kph. (1500 rpm and 0 kph) Boost seems un-affected.
I hope this is something simple and inexpensive!

pull the intake off and take a look at the wheel. If its scrapping up the housing then your turbo is about to take a dump. Also wiggle the wheel to see how much play there is

I believe I have solved my "slight metalic sounds"
First I listened to both sides of the turbo while it was idling with a stethescope and nothing but normal sounds. Next I got a friend to bring the truck up to 1500 rpm while I listened intently under the hood and narrowed the noise to the alternator area then had him shut the truck off. Next I removed the serpentine belt and checked the bearings starting with the alternator and found the culprit to be the idler below the alternator. Boy am I stupid.
I just hope it will get me home, 250km.
Thanx for reading and thanx for the help.

Good thing you caught it before it failed. I had mine idleing in the driveway and the idler decided to blow up right there. Ball bearings everywhere!! Very easy to fix, I just got a new idler from NAPA.

Yeah they are pretty simple to swap. I would think it should last the 250 km if you want to get it home, just keep a close eye on it (don't know what your shop/situation's like where you are but understandably it may not be ideal). Just keep the RPMs down and driver it nice, try to keep a low load on the alternator and A/C off, stuff like that to lessen the load on the belt and henceforth the idler. LR
