I have a1965 Plymouth belvedere 273 engine. There is about 30,000 miles on the rebuilt motor and compression is good. I removed the PCV valve and found a white milky sludge and a lot of water directly under the valve. The valve rattles when you shake it. The PCV hose is new. I drained the oil into a clear container and did not find any water or other contaminants in the oil.
What does this indicate?
The current PCV valve has threads and a small nut that holds it in place on a small metal cup that fits over a snout on the valve cover. The replacement PCV valve that the parts book calls for, does not have the threads or nut so there is no way to attach it to that metal cup. Anyone know how that is supposed to work?
