On DIY turbo rebuilds, a few years ago I was in desperate need of a turbo for my DSM. A friend had a 14b that was burning tons of oil. it was actually so bad that coaked oil was pushing the exhaust shield plate into the turbine wheel, damaging it. I put a new bearing and seal kit in it and reassembled to marks I made and the thing worked great! If you decide to do it, but the kit from g pop shop, not the eBay crap.
