The Stovebolt Site Forums The Shop Area The HiPo Shop Dirty little 5.3L L59 Secret

Gord, I think it is actually an LMG. I just sucked it up and had my shop switch it out for $400. Thanks for posting your article, apparently GM realized it was an issue. Contrary to the youtube videos, the GM tech guide advises taking the intake manifold off to get to the sensor. It's right next to the firewall. I made sure the shop used Delco parts including the little screen. I think the learning for me is, if you swap one into your Bolt, just go ahead and spend $30 on Amazon or Rockauto and replace it. Again, these are great engines....I've just never heard anyone mention it before. BTW, I only put full synthetic Mobil1 oil and GM intervals, so don't think it was gunky oil in my case.
