Hello,
We are traveling north on our 2006 Mainship 400 and while at anchor last night here in Beaufort NC, I was running our Kohler 8E0ZD genset for an hour or so and I noticed a slight diesel fuel smell. We were downwind of a fuel dock so at first I thought it was somebody fueling but being late that didn't really add up. I opened the rear deck hatch where our generator access is and opened the front sound shield door and with a flashlight I saw a small amount of diesel fuel in the mount base pan area. Not good.....
Upon further investigation, while the unit was running, I could see a small amount of fuel seeping out from what is the intake manifold?
I had wiped it clear right before the picture but the yellow circle is where the fuel was seen. (See pic)
I'm not 100% sure but I don't think diesel fuel should be in the intake manifold so my guess it was coming from somewhere else, perhaps above it and had worked its way there? Unfortunately this genset installation is not one that allows access or visibility to the upper side where the 3 injectors are so unless a larger access panel is cut I really don't know how else to locate the leak?
Since it seems to be a small leak could that maybe be a low pressure return line that might be leaking?
I am also pretty sure this is a 2005 Yanmar 3TN74 diesel.
Any suggestions or similar experiences would be appreciated.
