I'm in the process of changing the O2 sensors in my 2001 Range Rover. Easily accessible, but the front ones north of the Cats are a bit stuck. I'm sure they've been in there since 2001.
Last Saturday, I was able to get one out but it was tough sledding. Back and forth with the extra long wrench, heat, and PB Blaster. Now I need to chase the threads.
Long story short: It's now Thursday and I'm still sore in my upper back, shoulders, and arms. AND I still to take out the other one. Back two are already done.
