Has Nissan been giving a clear reason why the low pressure turbo is being replaced on the trucks that need it?
I just looked at the low pressure turbo that I got, that had been replaced as failed. No oil in the exhaust, shaft play is minimal, no blade contact or damage. The casting doesn't even have rust on it yet, so it's out of a low km truck. The only thing I can find is that the rotary valve seems to bind up easily. The rotary valve is part of the turbine housing casting, so if they wrote off the valve/casting they'd do the whole turbo. The rotary valve is removable though, so is Nissan just deciding they want to replace the turbo instead of fixing the valve?
