Another mystery to solve! I have a Yanmar 4JH4E engine in our boat and the strangest thing has been happening (for quite some time). Whenever we motor for long distances I end up with some antifreeze under the engine. Always about the same amount (4oz). I have looked all around the engine and have found no indication of where it might be coming from. I changed the exchanger cap thinking it might be leaking by when the engine is running hard but it still does it. We make long runs up and down the ICW and this happens pretty consistently. At the end of the day the reservoir is empty and the antifreeze is under the engine. I put a mirror under the engine and see no telltales from where it might be coming from. Nothing in the back or the front either. I am mystified! Any suggestions?
