hi my turbo broke today when going out on the highway i heard a pitched noise for about 10 sec and no power and amazing amount of oil smoke from the tail pipe i was able to go to next exit and stopped ther made some check under the hood but nothing obvius caled home to get assistance and towed home removed turbo and find a broken turbine shaft and plenty of oil in exhaust system ordered a exchange turbo it will come on monday and i will install monday evening thats how my day looked.
i hawe turbo problems for a period of time whith high boost in the morning and getting better after warm up but still not 100 % ok i know it was the unisone ring who was binding and i had plans to fix the problem but i am working plenty so as people do i put it for the future. so people out there dont do the same mistake fix and clean the turbo before total failure it will save a lot of money regards from peter and i am sorry about my english spelling hope you can read any way

Welcome to FTE peter!

You might consider installing the updated drain tube also.

The sticking unison ring shouldn't cause a turbo to fail in that manner. Even if it was allowing it to overboost, the turbo can handle a speed in excess of what the VGT can cause it to overboost. Unless the engine was over sped (Like it was forced to speed up by the vehicle), then there is a possibility.

Sometimes the turbos just go out. I have seen new ones go out, but nothing wrong with the rest of the system, sometimes they outlast the engine. They can be unpredictable, but 95% of the time, they are a high milage part. This is the basic turbocharger portion I am referring to, not the VGT portion with the vanes and unison ring and actuator.

I would do a couple checks to make sure you have good oil pressure to the turbo and a clear drain path. These are the of the most crucial points to keeping it alive. I would suggest updating both your oil feed and oil drain tubes as there is an updated version of them. That is of course if you do not already have them.

Besides crucial oiling to the turbo, other things that can damage them are oil coking in the bearings of the turbine shaft. This happens when the oil burns in the bearing from a hot turbo that does not get oil flow. This usually happens upon very hot shutdown when everything in the engine raises in temperature. Since the engine is not running, there is not oil flow, so the residual oil in the turbine bearings is cooked, causing burned oil deposits on the bearings.

When you install the new turbo, pre-oil it through the feed hole with fresh oil until is starts coming out the drain hole.
