Nutz About Bolts Prius Maintenance Videos

I guess wasn't tight enough. I used an impact. Loosened over a week. I drove two hours to visit family. Next day I went to weinerdogs at the drive thru I could smell oil burning. I had some trans leaking from seal but the smell is different. Pulled over and I see oil everywhere. Check oil on dipstick ok I have enough. I baby it home side streets. It was spraying oil from crankshaft seal. Pulley bolt I was able to remove with my hands. Now I marked the bolt and pulley hasn't moved. I never found the key. My uncle said the crankshaft might be no good. I used Loctite 660 let it sit for a couple days before reassembly. It's been almost 30k no issues. Im happy didnt happen two hours away from home.
