Hi Sinisa
I wish that was the case, the original lasted 15 years and 39,000 miles and the one that I swapped it for was out of a 93K car but I know what you're saying

Anyway, as the weather was so nice today I thought I would have another go at my exhaust system as Andrew had said he could smell fuel when I drove past him and I was continually getting the PO420 fault code and an EML. My thinking was that a possible exhaust leak could be throwing the lambdas out.

It took some prizing apart but eventually had the cat and the other two sections of pipe I'd welded off the car.

It looks like the copper wire gasket I'd made previously had held up well.

I plugged up 1 end of each pipe I'd welded and filled them with water to see if there were any leaks. The short pipe was ok but the long pipe had 3 or 4 pinholes in it which I welded up.
I had a look on the internet to see if I could fill the cat up with water but I couldn't get an answer for that so I had to make a gas tight rig up for pressurising the cat, this was what I ended up with.
For the rest of the afternoon I ended up welding rust pinholes on the cat so I'm going to persevere with it tomorrow but will probably end up looking for a new cat.

Well I spent another couple of hours today welding pinholes in the cat and finally gave up just after lunch. After assembly it does seem to run a little cleaner and on warm up the front of the cat wasn't dripping water on the floor so I think it's more gas tight now. I also cleaned the MAF as one of the little springs was a brown colour and it does seem to be running a bit smoother now. I'll give it a try tomorrow and see how it goes.
