Changes in temperature, UV rays, and the effects of fuel cause cracks to form in the rubber. If the spray test indicated problems but the boots outwardly look fine, they may still be causing issues.

This may produce a distinct coolant smell, along with steam, and drips or puddles of coolant underneath the vehicle. Coolant leaks should be addressed as soon as possible, in order to prevent them from becoming a greater issue. 3.
What happens when an intake manifold gasket goes bad?
A vacuum leak caused by a bad intake manifold gasket can throw off the engine’s air-fuel ratio and cause engine performance issues such as misfires, a decrease in power and acceleration, a reduction in fuel efficiency, and even stalling.
Is there a way to test the intake manifold?
If you have access to a diagnostic smoke dispenser, you can conduct a test of the intake manifold by placing the nozzle inside the throttle body and filling the manifold with smoke. Watch carefully for smoke coming out through the runners, or through cracks.
What causes a leak in the intake manifold?
The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil.
