Hi I've got a 1972 inline 6 that I just changed the motor Cuz the block was cracked in the old motor. I was adjusting the valves the other day, than ran it with the valve cover off just to see how it ran and noticed tiny water bubbles coming up the push rods. Now I've only changed the oil once before I ran the new motor basically I'm asking and hoping that if there was condensation or water in the motor would it come through the push rods not mixed in the oil or is the new-old motor cracked also
