i have a 95 honda civic 1.5L LX

I just replaced my exhaust.my new exhaust is made by Spec-R. ( for 92-95 civics)

My problem is my oxygen sensor cap fell off about 3 weeks ago. i havnt been able to find a replacement OR a thread size to just slap a bolt in it. as a quick fix i got some jb weld and a quarter( yes .25 cents) and jb welded it over the hole.. it fit perfect but JB will not hold it on. i need it fixed asap and i rather not have to take the exhaust apart to have it welded if i can help it

i have seen one person on the internet that said the thread size will be a 18mm but it was the stock exhaust. wouldn't they be the same size?

 

Use a spark plug should be m18 x 1.5 i believe its for lawn motors.

Also running th car without the o2 sensor isnt good. kills mpg and dumps to much fuel.

 

I don't think he's running without an O2. Possibly he has a second O2 bung and that is where the problem is.

 

i know. that's why im trying to fix it

 

ebay has them!!! http://www.ebay.com/itm/O2-Sensor-Plug-02-SENSOR-18-X-1-5-MADE-IN-USA-ONE-PLUG-ONLY-/200891054877?pt=Motors_Car_Truck_Parts_Accessories&hash=item2ec60a3b1d&vxp=mtr
its a M18 x 1.5 pitch not 18mm socket size bolt ..those are 2 diff types of measurements

 

Enough said. Thanks

 

or find an old o2 sensor cut the wire off screw it in and plug it or get one from a junkyard.... or buy a bolt like i posted above ... most hardware stores wont carry that size though
