Bad turbo????

This may be a repeat for some of yíall. I updated a previous post with these details as it all stemmed from my problem with an underboost code. Now Iím afraid I have a turbo problem.

I just had my turbo our to clean it because of an underboost code (P0299). When I split it open it looked pretty bad. The unison wheel was frozen onto the housing, and the vanes were really sticky. Even worse, quite a few of the fins had damage to the leading edge. I debated getting a new turbo, and decided that my existing turbo was making boost and showing no symptoms besides the underboost code, so maybe it would be OK to clean it up and put it back together.

I got it moving freely and put it back together, wrestled the sucker back in and finally took it for a test drive.

It sounds terrible. It sounded fine before I pulled it.

I remember years ago changing out my oil cooler I got air trapped in the lines and it sounded like I had exploded my engine. I donít remember how it sounded in particular, but I do remember that flogging it down the freeway cleared the problem right up. I didnít figure that pulling the turbo would introduce a lot of air into the system, but boy is it making bad sounds.

Almost like a grinding/whining sound, and when I hammer the throttle and the boost climbs the turbo starts really whining and it feels like grinding (or maybe Iím feeling vibration) and it seems like it might just let loose. When I get out of the throttle it mostly calms down, but when I stop completely and it starts to idle I get a very pronounced vibration.

Iím monitoring VGT % commanded and I have it set to give me alarms at 85% and 15%. When Iím in the throttle at high boost and I get off the throttle completely I get a super quick flash of 15% and then it instantly gets higher. Before when the vanes were stuck Iíd get 15% on occasion for several seconds and also 85%.

On the bright side, I didnít get the underboost code back, and all my monitors cleared and the sucker is finally ready for smog.

So......What do yíall think:

Bad Turbo?
Bad installation?
Air in the lines?
Bad Karma?

Seriously thought I had this one licked

Well, I got to work today hoping I had an exhaust leak. I checked the up pipe and down pipe to turbo connections. Both looked perfect, but it seemed like I didn't tighten down my down pipe clamp enough. So, I tightened it and hoped for the best.

Just like yesterday, the first minute or two of the test drive seemed fine, and then started hearing terrible sounds again.

Here are videos of the sound:

1. Me pulling a hill

2. Me on flat ground going slow on a side street

Then, add insult to injury I got a new Check Engine Light. P2290 Injector Control Pressure too low!

Did some checking and here is what I found with my monitor:

I found a post with expected parameters and ranges for ICP PSI, ICP Voltage and IPR duty cycle

ICP PSI
Key Off:0 as expected
Low Idle: between 577-582 should be 625.5
Operating range is from 0-4045 according to a post I found

ICP Volts
Key Off: .25 expected is .2 so that seems pretty good
Low Idle: .75 to .86 expected to be 1 not sure how bad that might be
Operating range .15 to 4.7

IPR Duty Cycle
Key Off: 15 should be 14.84 so that seems pretty good
Low Idle: 42 should be 24 this sounds bad to me
Operating range according to the post I found should be 0-50%, however when I goosed it in park it climbed over 60%. Does that mean that the range actually should be greater and the post was wrong, or that I went out of range?

Lot's of questions:
1. What in the heck do you think that sound is?
2. What do you think is wrong and throwing my ICP pressure too low code?


Grrrrrrr.....getting frustrated. Thanks for the help

Sounds to me like the turbine is contacting the housing
I would suggest pulling the turbo and inspecting where it is hitting

the turbine spins pretty fast and needs to be in balance -- you mentioned damage
not sure on these Ford turbos, but on my tractors the turbo spins around 90k rpm at full load

I would do the checks before she spits chunks into the engine

Pull your air intake hose off and grab the nut on the compressor wheel and see if you can wiggle it back and forth or up and down. If you can move it more than just a hair then it could be bad bearings allowing it to jump around and contact the housing. Sounds like that is the problem, especially since you said there was damage to the blades. Damage to the blades will also cause a loss of boost.

Thanks for the reply. I checked the wheel on the intake side before installing and it seemed perfect. One of the blades was a bit worn looking in that the finish was coming off and I could see the green base material underneath the silver coating. All the fins on the compressor side looked to perfectly shaped. It was the exhaust side where I saw the damage but strangely only on about 25-35% of the fins. I didnít check for play on that side (like an idiot). It is building boost like normal.

They ride on the same shaft, if there's play you will be able to feel it from either side. Well, you should be able too. Someone may comment and make me a liar lol. Having that much damage on the turbine side will definitely affect how fast the turbo spins and how much boost it can create.

Edit: I see you said its building boost normally so that's not an issue yet, other than the underboost code that appears randomly. May not be related, I'm not an expert by any means. Definitely check for play though.

Agree with the above answers. Sure sounds like the compressor and/or turbine blades are contacting something!

Hydro, your suggestion is to pull the turbo and check it out right? Thanks for taking the time to read and reply.

Couple things have me confused:
-the exhaust side fins were damaged when I pulled it the first time, but the turbo was spinning great.
-it doesnít always make that sound, wouldnít it always sound terrible if something was out of alignment?
-why after pulling my turbo and reinstalling it do I have and ICP pressure too low code and readings that seem out of spec?

Anyone think that sound could be an exhaust leak from the turbo? Iím thinking that maybe I didnít do a good job getting the two halves of it together.

Pull the turbo before you damage the engine

The vanes on the exhaust side if worn and if the shaft bearing is also worn -- can come into contact when the turbo is fully closed
also need to be sure of the case alignment -- since you had it apart

The vanes move close to the turbine wheel when the VGT is at a high percent value
pressure is from the outside towards the center -- if the slots or the vane tab have too much wear, they can contact

Something was gnawing on the turbine fins already

it is possible to get a new turbine and bearing kit for a cheapo rebuild, if the rest of the parts are still good

Here ya go, lots of rebuild vids on the tube
