My Chrysler 440 is getting water in the oil. It has internal cooling also but appears to be fresh water. Any ideas on where to start to find out how it is getting in? The exaust manifold on the port side of the port side engine appears to have a crack that has been repaired before. I have new intake manifold on the engine. This appears to not have been an issue until i put a new impeller in the fresh pump. That is when i found the cracks in the v drive which is out getting repaired also
