Guys i need help, i need to change my o2 sensor quickly, but the peice of **** is hard as hell to get off, is there any secrets or any useful info on how to get it off, tried search but nothing came up.
Thanx

 

did u try a wrech and tapping it with a hammer/dead-blow?

 

tried a cresent wrench, ****** is tight on there

 

Get some penetrating oil like WD-40. Get a REAL wrench. I had to go to wal-mart and get the correct metric sockets for my drain plug because the crescent wimped out on the bolt. A correctly sized wrench actually DOES help...

I'd just take the penetrating oil, spray it, let it soak for a few minutes, and lightly hammer it to break the rust or whatever free if needed. Then use the real wrench.

 

try some heat if ya can. if not try some pb blaster or some w-d and let it soak for a lil. use the right size wrench!!
