RSW European Auto Repair can help if you have a cracked exhaust manifold in your Infiniti. The most common reason why an exhaust manifold will crack is excess heat in the engine. We cannot stress enough how important it is that you do not drive your Infiniti if the engine is overheating. The following are signs that the exhaust manifold has cracked and is leaking exhaust into the engine.
Sluggish Performance
You will notice that the Infiniti’s engine performance will start to lag as the engine fills with exhaust gases. This is because the gases make their way into the combustion chamber and interfere with the combustion production. Consequently, the Infiniti’s engine and acceleration will become sluggish.
Reduced Fuel Efficiency
This will create a problem with the Infiniti’s fuel efficiency. The engine gets its best fuel mileage when it is running as efficiently as possible. The exhaust gases interfere with the engine’s efficiency, and, as such, the Infiniti will burn more fuel when it is running. This can be frustrating if you’re on a budget.
Strong Burning Smells
Your nose can also detect that the exhaust manifold is leaking. As you can imagine, engine exhaust is quite hot. As it leaks into the engine, it will overheat metal parts and raise the Infiniti’s engine temperature. It will also overheat parts made of heat-susceptible materials and melt them.
Strong Exhaust Smells
Aside from smelling the burning odors coming from the engine, you may also smell the Infiniti’s exhaust. This can be a huge problem that is dangerous to your health. It’s easy for the ventilation system’s fan to draw the exhaust gases through the vents and into the cabin. This can make you seriously ill.
Noises at Start-Up
Sometimes, the leaking exhaust will hiss or tap when you first fire up your Infiniti. Listen carefully as you press the start button or turn the ignition key. These noises may not last because the exhaust manifold can actually seal the crack out of which the exhaust leaks when it gets hot and the metal expands.
Check Engine Warning
Finally, it may come as no surprise to you that the engine control module will turn on the check engine light. Your Infiniti’s engine is struggling because it is filled with exhaust gases. This can cause various sensors throughout the engine to send malfunction codes to the engine control module.
