I'm replacing my o2 sensor in my jeep. The old one looked striped. Tries to put in the new one but it will not go in. Is the port striped? if the port is striped and i have a new o2 sensor can is there another way to put it in? everytime i try to put it in but it wont screw

 

The treads might be the same as some spark plug hole chasing taps that might be cheap at Harbor Freight. You might be able to clean up the hole with something like that...The one on my Renix Jeep looks like the large Ford type thread.

 

Is a tap hard to do ive never done one is it as simple as screwing the coil into the hole?

 

No, not hard. It's sort of like a bolt, but tapered with cutouts for shavings. You just screw it in and it cuts the treads clean. It's called "chasing" since you are not actually tapping new threads. Actually, that chase might have a handle like a screwdriver.

 

Found this on Ebay http://www.ebay.com/sch/i.html?_kw=s...ug+thread+18mm

 

So i just need an 18mm chase and i just screw correct? Do i have to heat the hole first

 

Doubt you would need to heat it, use some oil though. This might be the cheapest one> http://www.ebay.com/itm/14mm-18mm-Spark-Plug-Hole-Thread-Chaser-Tool-Chasing-Plug-LIQUIDATION-/281439631224?hash=item41871bf778&item=281439631224&pt=Motors_Automotive_Tools&vxp=mtr

 

Thanx Ill try it tomorrow ill let you know what happens.........

 

Done this on mine with exact tool. Im Reinx not sure about newer years size.

 

Just dealt with a similar issue on Ratmanche ... PO of my HO manifold had left a sizeable portion of the O2 sensor threads in the manifold bung. Just pried and picked them out with a small screwdriver. Manifolds are far harder material than the sensor threads.
Renix and HO threads are the same (have a 93 manifold on my 00 XJ and a 94 manifold on my 88 MJ ... Both using stock sensors).

 

You won't get a better reference than that.
