When your Eagle catalytic converter begins to fail, do not rush yet to replace it. First, take the time to determine the cause of the failure. After all, a catalytic converter is not cheap to replace and the underlying causes might just remain and shorten the lifespan of the replacement component. One cause of failure for a catalytic converter: clogging. The catalytic converter needs the free and easy flow of the exhaust gases through its channels to work properly. Sometimes oil or coolant fluid will leak into the exhaust system because of failing gaskets, valves or piston rings. The coolant or oil will evaporate in the extremely hot conditions of the catalytic converter, leaving carbon deposits that accumulate and eventually block the flow of exhaust gases. The catalytic converter can be 'poisoned' by the accidental use of leaded gas, which will completely disable its functions. When the exhaust system emits too rich (too heavy in fuel), the catalytic converter will eventually overheat and fail. The too-rich fuel mixture can be caused by faulty oxygen sensors, MAP sensor, fuel injectors or problems in the combustion cycle. Repeated misfires and 'bump starts' will send too much fuel into the catalytic converter. When that happens, the fuel ignites as it reaches the hot core of the converter. Too much ignition creates too-high temperatures, causing the catalytic converter to fail under heat stress. Once you have diagnosed the reason for your catalytic converter to fail and addressed the problem, order your new Eagle catalytic converter from our site and install it with confidence that it will last a long, long time.
