Hi, can I ask you a question. I have cleaned the PCV valve, looked real clean and fine. My problem is that I have blown 2 crank oil seals. When checking the second one I could have pressed it in another 1,5 mm, maybe that is why it flipped out over the edge. Anyway, how can I check if pressure is too high in engine? A friend recommended me to take off the oil filling cap and check if its puffing. Is there a better way?
