o2 sensor question


had to buy a new o2 sensor (before cat) because the fucktards who installed my motor (after i blew the original one) fucked up and totally screwed up the threads on the o2 sensor.

i was driving in traffic, all of a sudden hear a loud noise, and it sounded like my muffler had fallen off. popped the hood and realized the o2 sensor was fuxored.

anyways, just bought a new one, to the tune of 90.00 and was wondering, do I need to put any thread lock (loctite) onto the threads in order to secure it in? it just screws right in....

if i am not mistaken just be careful tightening it if your going to use an open wrench, the area tends to warp some under heavy load.
