About to be on turbo #3

[mysticblu999]

10k miles after my first turbo replacement I'm going to need another one. The bearings are about to go. I anticipated this about 1k miles earlier. The surging while towing and the really high-pitched whine was back. Now I have the low-pitched whine like the last time it blown back in March. It still makes boost and has not started smoking but it is starting to rattle. It is down on power though. I parked it and got my trusty '98 Mercedes E300 turbo diesel with 335k on the clock, still on the original turbo, injectors.....

These turbos are junk, junk I tell you. Please someone tell me there is an updated turbo.

This not very incouraging, I was thinking only the cab/chassis small turbos were giving problems. My turbo went out at 34K and this one has been starting an intermitent whine at 44K. I was planning to eventually upgrade to the Regular Turbo to end the headache. Good luck and keep us posted.

Sounds like me. First one went out at 36k now I'm at 47k

Knock on wood.. I have a 2011 Job 1 truck that I bought in 2010, I haven't had an issue yet with my turbo, but seeing more and more on here is kind of making me worry! Do you guys return your trucks to stock before you take them in for issues like this?

Not trying to be a smartass but how can you hear the 'whine' from the turbo? It must be pretty loud? All I can hear from my truck is exhaust and tires. My truck seems to be fine, or at least I think so and I can't tell any difference in the engine/turbo. It does drive a bit different now with the .19 update from H&S but otherwise it always drives the same.

It would be nice to know when the turbo is starting to fail ahead of time. Any additional info/details on what we could look/listen for would be greatly appreciated.

I'm not looking forward to returning my truck back to stock to get a new turbo.

Mine is stock, just got new DPF yesterday, and that was hard to do, but since I still have warranty I'm protecting it. If I was to change anything, I would start with the turbo, but even though all I want is a Regular Ford Turbo, they said my warranty would be History.

I second what Andrew said... Would it be possible for anyone with turbo issues to upload a sound or video clip so others know exactly what to look/listen for?

One other thing, what do you mean by 'hasn't started smoking yet but has started rattling'? The rattling part is fairly self explanatory but smoking? Smoking under the hood or?

Again, seriously not being a smartass.

The only advance warning on mine was after shutting engine off, on occasion as the turbo was spooling down I would hear the whine/grind of a bad bearing sound.
When the turbo failed, it idled fine but had the sound like a dry powersteering pump and/or alternator. This was the main time I missed a Voltmeter. When I revved it up I noticed Zero boost pressure and sluggish. Mine didn't smoke while I limped it home, but did smoke the next morning on way to dealership. (out the pipe) but only for about 1/4 mile.

I looked at the old one and the thrushaft bearings had failed and it was wobbling around in housing.
No worries about sounding like a Smartass, That was a Fair Question. Glad to be able to help any way possible. That's what makes this Forums so Great.
