That $600 'rebuilt' turbo I bought off Facebook was a parts bin special
Last month I snagged a 'low miles, freshly rebuilt' turbo for $600 from a guy in Midland. Bolted it on a 6.7 Powerstroke for a customer and it smoked worse than the old one, plus the wastegate stuck shut. Pulled it apart after 3 days of chasing fuel pressure and found mismatched compressor wheels and a scored bearing race. The seller blocked me when I asked for a receipt or any rebuild paperwork. Cost me $180 in gaskets, oil, and my Saturday to learn that lesson. Anyone else gambled on a sketchy online turbo and lived to tell about it?
Wait, a 6.7 Powerstroke is a diesel, right? I only ask cause wastegate and compressor wheel stuff is usually what you deal with on gas turbos, so I'm wondering if you meant something else. Not trying to nitpick, just sounds like maybe you meant a different truck or the guy sold you a turbo off the wrong motor totally.
