After I reinstalled my carb I had my mom sit in the cab and rev the engine. She put it into drive and at high RPMs, some white smoke (combustion blow by gasses?) came out of the PCV filter hole. There was no filter at the time, but I have since put one on. What's up with that? The PCV valve clicks like its sposed to, and there's plenty of suction at that location. How bad is this? What can I do about it?
