Can Sea Foam Motor Treatment clean oil screen in my GMC Sierra? [SOLVED]

Will Sea Foam in the oil clean the screen below the oil pressure check sensor in my 08 GMC Sierra? I’d rather not have to take the intake manifold off to replace a 5 dollar screen and the sensor is in good condition.

Hey Carl. No matter what, adding Sea Foam to oil will work to clean anywhere oil flows in the crankcase, so it’s always worth a try. Just pour half a can into your crankcase every interval and see if the code clears.
