Can spark plugs affect catalytic converter?

Bad spark plugs or damaged exhaust valves can also destroy a catalytic converter. It is important to keep your engine and fuel injection system in good working condition. There are a few things you can look for to determine if you have a damaged or clogged catalytic converter.

What is the average life of a catalytic converter?

The catalytic converter, which converts harmful emissions into harmless gas, often lasts 10 years or longer and should be replaced only when needed. It can become clogged, physically damaged, or contaminated by oil or engine coolant.

Will burning oil clog a catalytic converter?

The oil that's burned in the engine ends up flowing through the exhaust system, where it can eventually cause catalytic converter failure in much the same way as a coolant leak.

Can you clean a catalytic converter instead of replacing?

As we indicated at the beginning of this article, cleaning a catalytic converter is not recommended by any vehicle manufacturer. It can damage the internal catalyst and render this mandated system useless. The best solution is to have a professional mechanic replace the catalytic converter.

How long can I drive with a clogged catalytic converter?

A Catalytic Converter Can Be Driven Indefinitely

In the case that the catalytic converter is totally plugged, it will prevent you from running your vehicle. In some situations, it may come to be completely fused directly or overtime, and it will need to be replaced immediately.

Is it worth fixing a catalytic converter?
