My Cherokee, like may others its age, has a slight blowby problem. It is not too bad, but enough to notice when looking at the air filter. So, thinking back to when I used to race go-karts, I made a catch tank out of pvc pipe to catch the oil blowby. It is really a simple concept. The pcv tube goes into the tank, and another tube goes out to the airbox, hopefully leaving the oil in the tank. I just put it together tonite, so I don't know well it works yet, but I will find out, and let you guys know.
