Well I just did a seafoam treatment, (smoke was awesome) replaced my plugs, changed the oil, now workin on the o2 sensor. I got the right size box wrench (7/8) but i cant manage to get leverage nor an angle to get it in there and unscrew it. Any ideas?
Thanks

 

Got any sort of piping...something to use for leverage?

 

go to a local auto parts store or hardware store and pick up an O2 sensor socket. It has a slot down the side for the wire and then you can use an extension with the ratchet. The socket should only be about $7-$8.

 

or u can do it the hard way by jacking up the car, loosening the heat shield, holding heat shield to side and then stick a wrench up in there from underneath and take it off. thats how me and my frend did it on my sohc ka.

 

I just changed my O2 sensor today . Tried wrenches and almost rounded it off . Ended up paying $11 at Autozone for the O2 Sensor socket and it came out no prob .
