Toyota Corolla headers are the first part of the exhaust system that is responsible for getting the byproducts of combustion out of your car. When these begin to break down, it may be difficult for you to detect them because the failure of these isn't that common. Most are built to be tough and strong to last for years. Your ability to notice the earliest and faintest symptoms of a broken set is important for your car's performance and for your safety as well. Here are some indicators associated with leaking Toyota Corolla headers.
Loud exhaust noise from your car can be caused by other parts in the exhaust system. As far as Toyota Corolla headers are concerned, the probable reason for this is cracked and broken headers. Gaps are created because of the continuous heating and expansion of the metal. Overtime, the stress is just too much for the headers to handle. Other audible signs of leaking headers include continuous hissing and popping sounds. The extra noise you hear is the combined sound coming from the tailpipe and gaps of the Toyota Corolla headers.
You may notice some discoloration and burnt paint in the ends of the Toyota Corolla headers and engine meets. Also, the accumulation of rust, no matter how insignificant the amount is, is an early sign of decay as well. The surface may only have few rustic spots on it, but it is never obvious how bad the damage could be on the inner face.
When you place your hand near the Toyota Corolla headers while the engine is running, you may feel hot gas escaping from the area. This is also a sign of leaking headers. This is caused by the worn out pipes and gaskets connecting the headers to the engine. Extra rattling and shaking sensations are also clues pointing to wobbly parts.
Escaped exhaust fumes because of leaking Toyota Corolla headers have a tendency to enter the passenger cabin. When you drive with your windows rolled up, the gasses are trapped and have nowhere to go. If you suddenly feel dizzy and nauseous while driving, chances are you have already inhaled enough exhaust fumes to inhibit your driving ability.
