I am posting a video of my newly acquired 1999 Dodge Ram 2500. There seems to be some blow-by coming out of the vent tube. Nothing comes out of the dipstick or the oil cap. New to these trucks, and I am concerned with this. Could anyone please tell me if this is acceptable or normal on these trucks? I understand the crankcase has got to vent but didn't think it would be seen this much. Engine has low miles (around 130k).
