Is there inexpensive way to check for leaks in the intake manifold?

Yes, while the engine is running (in park) spray gumout/carb cleaner along the egdes of the intake. If the motor runs smoother or better then that tells you the intake is leaking. This, however, could cause a fire. A safer way is to use an unlighted propane torch. Turn the fuel on low and slowly move it along the hoses and gasket surfaces. When the engine speeds up, you have found your leak. if you are not sure if there is a leak in the intake ;a good way is when the engine is at idel carefuly place a rag over the carb or throttle body slowley closing the opening ( hold the rag tightly )while slowley placing the rag over the intaks ; if you notice an increase in RPM then you probley have a vacumm leak; to help pin point the leak use a spray with water and slowley go around the base of the carb ;manifold and vacuum lines when the RPM'S increase check that area for leaks ; cracked vacuum lines ;intake gaskets leaking this should help

Can a intake manifold gasket cause antifreeze to leake?
Yes. Antifreeze is actually pumped through the intake manifold. If the gasket is bad it is possible that it leaks out
What effects happen when and intake manifold leaks?

Check for leaks in the intake manifold or a poor fuel pressure situation.
Why is your 1987 Chevy van idle high when you start it?
Check for vacuum leaks. The gasket was known to blow out between the throttle body and the intake manifold.
Is there a spray sealant for air intake leaks?
Not that I've heard of. Replacing the gaskets and inspecting the manifold for warping or cracks is the best way to stop intake vacuum leaks.
What are the symptoms of manifold exhaust gasket leaks on a Chevy truck?
Intake manifold leaks will cause the engine to idle rough and get poor fuel economy. An exhaust manifold will have no symptoms other than the sound of the leak.
Antifreeze leaks along the valve covers?
Could be the intake manifold gaskets are leaking.
What could be the problem for coolant leaks under Chevrolet suburban 1996?
Intake manifold gasket
What problems on an 1989 GM S15 that has soft brake pedal no leaks at MC but must crank 12 times and pump brakes to start?
start by checking the master cylinder break booster by unplugging the vacuum hose connecting it to the intake manifold and capping it, if it starts easier you might have an internal failure in the booster. If not, check for leaks in the hose its self and manifold leaks.
How do you check for a blown intake gasket?
Look for leaking antifreeze/coolant. Usually you can see it leaking around the top of the engine. Also check your oil, if it looks milky it has been mixed with coolant and you intake manifold gasket is leaking. That being said, it is possible to have a leaking intake gasket with no sign of leaking antifreeze. Most intake manifold issues/leaks are coupled with poor engine performance and even sputtering and lack of power.
Why would 2000 impala 3.4 run 220 degrees when at idle?
Have the head gaskets checked and intake manifold gaskets checked for leaks. The 3.4's are known for head and intake leaks! Or a bad thermostat.
Why is your Toyota Corolla idling high?
replace the air idle control sensor on the throttle body ********* also check for vacuum leaks, hoses fallen off or deterioriated, or intake manifold gasket
