Signs of a Damaged Jeep CJ7 Intake Manifold Gasket
The intake manifold gasket is a small component that plays a big part in ensuring optimum performance from your Jeep's engine. As the intake manifold gasket continues to be subjected to lots of pressure, it can eventually cause dangerous leaks. Here are some signs of a leaking Jeep CJ7 intake manifold gasket:
An overheated engine is often caused by low coolant level. If you keep on having to top up your coolant, there is a chance that a damaged intake manifold gasket is causing your coolant to leak out. Coolant leaks don't only increase your engine's risk of overheating. Over time, your leaking coolant might mix with your engine oil and lead to the complete failure of your engine.
Check beneath your vehicle or around the intake manifold gasket for puddles of coolant. Don't forget to check your engine oil as well for signs of coolant contamination. Use an oil dipstick to examine the state of your engine oil. If it has a milky consistency, then your intake manifold gasket has caused an internal leaking problem.
Decreased fuel mileage and increased emissions
Just like most exhaust system problems, a leaking intake manifold gasket can also result to poor fuel economy and increased emissions. Since the intake manifold gasket plays an important role in maintaining the perfect air-fuel mixture for your engine, any damage on this particular gasket can also affect the mixture. If you are certain that your exhaust system is in perfect condition but you're still getting less miles per gallon, then you might have to check your intake manifold gasket for leaks.
A whistling noise from the intake manifold can be a sign of a cracked or deformed intake manifold gasket. If the damage becomes bigger, the whistling noise might turn into a deeper, gulping noise as the intake manifold takes in more outside air into its system.
Poor engine performance
As your intake manifold gasket fails, your engine performance also suffers. When you start experiencing a rough idle, stalling issues, and loss of high-speed power, then you better check on your intake manifold gasket.
