Intake Manifold crack Symptoms !!
The intake manifold of the Ranger is known to crack without any warning signs beforehand. You will do well to regularly inspect the Intake Manifold for fine cracks and tears. One way to inspect is to allow the engine to idle for a bit to build up pressure, then run your hand along the Intake Manifold to feel for any air blowing out.
Next, shut it down and listen out for any sucking noises emanating from the intake pipe that indicates a leak.
Symptoms of a cracked Intake Manifold include the following:
Engine running hotter than usual
Dip in performance
Lots of black smoke emanating from the exhaust
Fully of dirts carbon on the intake will block the Air Sucking
