What's up everybody? I have a 97 Rav4 4wd that I am rebuilding basically from the ground up. I bought it from a neighbor who said it was taken care of and loved. Which means he put gas in it. Anyway long story longer I have an oxygen sensor that I need to get out of 23 year old rust and corrosion. Any ideas? I have tried all the usual go-to's (blaster, heat, offset socket, breaker bar, tapping on it) so I'm drowning.
