Hi and thanks for contacting YourMechanic. When the Check Engine Light flashes, it means that there is an intermittent problem making the light flash on and off. When the light flashes, it is best to pull off the road and...

You could have a couple causes of the oil leak at back of intake manifold. (https://www.yourmechanic.com/services/oil-fluid-leak-inspection) This engine oil pressure sending unit is the most common leak in this area of the engine. Replace oil pressure sender if leaking.
