I've got a relatively new GTB1756VK that I've been running on my BHW for about 10,000 miles. In the last few months, it's only been pushing a max of 25 psi because my tune hasn't been finalized. That's only when flooring it, it usually runs much lower than that.
Today, the ECU kept going into limp mode, complaining about "boost control level not reached" or whatever. When I looked under the hood, there was a mess of motor oil around the turbo and the ProVent was full of sludge. I took off the turbo inlet pipe, and the compressor housing is dripping with oil.
The compressor wheel has maybe 0.25mm of wiggle in every direction, it's minimal. It turns freely, there's no binding whatsoever, even if I push it in any direction while turning. The engine otherwise appears to run just fine.
What causes the turbo bearing seals to fail? Is that what I'm looking at here? Is it rebuildable? I spent a pretty penny for a custom-built turbo that supposedly has a billet compressor wheel and "uprated" seals, I kinda expected it to last longer than this under unabussive circumstances.
