An automobile's exhaust header is a very important component in the whole combustion process. It is designed specifically to take the burned gases out of the engine block and into the exhaust pipes. Having these gases go back into the engine and undergo the combustion process again will pose detrimental risks to the whole of the vehicle. More so, if the headers let these gases out at the wrong place, it can be a health problem to the driver and passengers when inhaled. These reasons are why you should be extra conscious on troubles with your headers. Following are some signs to help you be certain that your Jeep Wrangler headers are not working as they should be.
A strong and unusual gas odor will be emitted by the tailpipe if there is an issue with the exhaust pipe, particularly the headers. This is due to leakage in the headers or blown up gaskets. The strong odor comes when an amount of exhaust gas escapes through the leak or the damaged head gaskets. This symptom comes with a large concentration of soot on the whole of the exhaust pipe.
Another symptom of a leak is an unusual knocking sound heard from under the hood, especially on the exhaust header part. This sign is very difficult to detect especially while driving because of the normal engine sounds. Nonetheless, you should be extra conscious and give close attention to such unusual noises.
A common manifestation of a blown up gasket is rough engine run coupled with compression loss. These happen because the exhaust fumes from the engine block are not delivered well into the exhaust pipe, causing back pressure which reduces engine performance. If such problems occur, inspect your head gaskets, locate the damaged one, and replace it immediately. Blown gaskets are common in automobiles.
The second typical sign of a damaged head gasket is blue exhaust smoke coming from the tailpipe. While you may find this amusing, this can be a serious problem as a head gasket or two is obviously damaged. The blue smoke comes from oil or coolant seeping through the exhaust pipe. These contaminants burn inside the pipe, damaging it through the blue flame.
