I changed my oil and made a big mess

It wasn't due for an oil change for another couple thousand miles, but it smelled like gasoline so I wanted to get it out before it ruined my rod bearings. I attempted to replace my O2 sensor while I was down there, but I couldn't get it to budge

I gave up because I didn't want to snap the bung off and have to remove the exhaust to get it welded back on. I guess I'll wait until I get some PB blaster or something to loosen it.
I was amazed by how clean the bottom of my engine was compared to the top.
W00T!!!!! I got that mother ****er off!!!!!!!! The only down side is the threads for the oxygen sensor are destroyed

I guess that ****er didn't want to go quietly





Here's what happened to the threads on the O2 sensor:
So now I guess I need to remove the exhaust to retap the hole. I tried removing the nuts that hold the exhaust to the headers, but they're rusted on there so I guess I need some PB Blaster or Liquid Wrench...
