PCV check valve cleaning from a 1997 Dodge Ram 1500. I video'd the third clean. My ball was stuck. I used berrymans b12. It burns a little at first, but that subsides. You can also use brake cleaner, just spray it right on there, fill up that ball holder, real good. Then shake your ball. First 2 cleans revealed stuck black balls, dirty dirty dirty. 3rd clean the ball was flipping and bouncing all over in there. That's what you want, bouncy, free breathing, commando style check balls.
NOTE: A Positive Crankcase Ventilation valve is designed to recycle hot gasses and pressure in your engine crankcase sending it back thru the carb or intake with fresh fuel and air, therefore burning the pressurized crankcase gasses cleaner. If your balls are stuck, you may blow a gasket, and severe leakage may occur... You don't want that.
