So the turbo went on my MQ at 114,000klm, just out of warranty.
The guys at diesel care in Dalby put a new turbo on it and it killed the new turbo in a day or two.
The second turbo is away getting "assessed" as to what killed it but they are assuming low oil pressure and think to chase up the issue that they might need to take the whole engine out, which is not gong to be cheap.
I have run a catch can since about 70,000klm, but have never had a look at the manifold. (this is just an FYI on the car, and not necessarily what i think is the cause)
Apparently one of the injectors has a washer that is letting carbon blow past it. At this stage they suspect that there may be a carbon blockage in the pickup tube, or something like that? (But they really don't know yet)
Has anyone heard of anything like this before?
It was down 10 to 15% on power when they put it on their dyno before the second turbo went.
Also, when i asked about the intake manifold, they said they can do their "prostream" terra-clean intake system clean with the manifold still on. Has anyone had any experience with this from diesel care, and is it worth doing, or should i just be spending the money on manifold removal and off-vehicle clean?
Frustrated and without my MQ, just a month before i go on holidays and need it to tow the boat.
