Has anyone ever used Dura Lube Severe Catalytic & Exhaust Treatment before? If so how did it work or does it even work?
Oh I know the problem will be back. My goal is to clean the system up some and keep it running smoother-ish while I save the $$$ for the new cat.It'll be back. That stuff doesn't put precious metals back into the convertor, and that's the problem. Make sure the car is running tip top to protect the convertor. That's the main point of the fuel feedback system - protect the cat.
Yes... I've used that method for testing purposes and like it. I wish I could have used it to get through my emissions inspection.
I would still attempt it on a vehicle that isn't worth a new CC for what ever reason. Worst they could do is fail you and send you on your way.Yes... I've used that method for testing purposes and like it. I wish I could have used it to get through my emissions inspection.
The technician doing the inspection had a mirror tilted on wheels that he slides under the car. I don't know if he was looking for a missing catalytic converter or if he was looking for the anti-fouler thing. I was kind of scared to take the chance, so I just put on a new cat every couple of years.
Thank you PoMan. How do I do that mod? Any how to videos online? And does this mod affect the way the car runs?@CJK I'd do the sparkplug anti-fouler mod to the downstream O2 sensor bung on your Versa. It might push that sensor out of the exhaust stream enough to keep the catalyst inefficiency code away. It's not a legal or legit fix obviously, but its OK for the DIYer to do. None of the shops I go to for yearly state inspections would notice or care.
Just google it. It's just a threaded fitting that you thread in between the downstream O2 sensor and the exhaust system. You'll have to remove the downstream (rear most O2 sensor), thread in the anti fouler or even 2 antifoulers, put the O2 sensor back in and drive the vehicle. They work by keeping the sensor out of the exhaust stream just enough, that is see's an O2 content that may (and I stress may) keep the catalyst inefficiency code away. If one doesn't work. Try two of them threaded together.Thank you PoMan. How do I do that mod? Any how to videos online? And does this mod affect the way the car runs?
My state doesn't have emission tests any longer. My main concern is keeping Vera (Vera the Versa) on the road and running as good as possible, for as long as possible.As far as inspections go with a spacer on there, I don't know if it's part of your states rules to check or not. In NY, we'd consider it tampering, and depending on the inspector, it would fail if they saw it and cared. They're pretty obvious, I think at least.
