My Uniflite (’84,42’,SE II) is powered by 8.2L Detroit Diesels. Starting this year (2010) I have noticed an oil slick that comes from the exhaust of my Starboard engine. I also noticed that when I first rev up that engine (to set the alternator to charge) I get a puff of white smoke. I just finished an annual, 10-day, cruise and I have been plagued by the oil slick and the oil consumption on that STBD engine. I have been worried about the engine as long as I have owned the boat because it is older than the Port engine (indicating that some former owner may have abused them) and it exhibits low oil pressure (~40 psi which drops to nil at idle) and has always use oil more so than the newer Port engine.
This latest excessive use of oil is unacceptable and I am thinking about a rebuild or replacement. The engine has about 1850 hours. The oil definitely ends up out the exhaust and on to the water. My first thought is about blow-by. Now I’m wondering if there is somewhere that a seal could have gone bad allowing the oil into the exhaust, say in or around the turbo charger. I am going to check the actual oil pressure, but I don’t know what else to do, and that doesn’t suggest anything about the cause of the excessive usage. Now that I am writing this down it has accrued to me that I am not burning the oil. There is no smoke! And, there is no blow-by present at the breather. There is no dripping or leaking oil from the engine. There is just a lot of oil being dumped into the exhaust – like a couple of quarts each day. Does anyone have any suggestions? I have yet to find a mechanic in the SF Bay Area that truly know about the marine version of this engine (but I’m about to try again).
