Is there any exhaust shops open on a sunday? In particular chains, like HiQ, Central tyre, quickfit etc etc.

As the guy who did my decat did not use the spark plug anti fowlers i decided to fit them myself, it appears the thread on the decat pipe is possibly crossthreaded meaning the spark plug anti fowl adapters will not go in and nor will the original o2 sensor.

If no exhaust shops are open does anyone know where I can get a 18mm tap?

Thanks

How the hell did you manage that? you've most probably just got some of the aluminium from the anti-foulers in the thread on the decat, just take the decat off and you might be able to get it out with something.

Thats what I need to do take the pipe out and then fit the anti fowlers in put the pipe back on the car then add the o2 sensor, Its 5 more bolts to take off then do back up but will sort my problem. Its awkward being under the car when its on ramps with it getting darker, i'll attack it again tomorrow morning.

I cant think how it was crossthreaded, it was kind of hard taking the o2 sensor out.

Oh well, do focus/B&Q etc sell 18mm taps (not the kind water comes out of )?

Thanks

Oh, if it was hard taking the sensor out maybe the monkey who fitted it cross threaded it putting it in.

There is no way those soft anti foulers would screw the thread up.

B&Q wont sell the taps you want I bet, I think Halfords sell them.

I wouldn't think many places will sell the taps, it's a weird size, from memory I think it's 18mm * 1.75mm course thread.

Just try screwing either the anti foulers or O2 sensor in and out of the hole a few times, try some copper slip on the thread also, then try wiping all the crap out of the hole.

I would say borrow mine, as they were hand cut so a better thread, but they are locked away at Honda with the Spoon exhaust
