Fuel/Oil slick from exhaust of Turbo Diesel
I have twin 135 hp Turbo Volvo-Penta Diesels. The Starboard engine is
starting to send fuel or oil out the exhaust causing a slick on the water. The Port engine began to use more fuel since this began. I have also noticed that the Starboard engine was using a lot more engine oil than the Port engine. In the past , both engines used very little engine oil. Does anyone have any suggestions as to what my problem might be? Thanks |

Thanks It sounds like your oil cooler has a small leak, you could also have a fuel cooler or a transmission cooler leak. But if that engine is using oil it's probably the oil cooler. I would have a pressure test performed. If their's a leak the system won't maintain pressure and a slick will form (as long as you don't have a water lift muffler) without running the engine. A faulty injector could give you the oil slick, but not increased oil usage. How did you determine the port engine is using more fuel? Those fuel flow systems are not very accurate, it's probably a coincidance. |
