Anchored in beautiful Barnegat Bay today after a 10 hour run from Cape May. Checked the engine oil after a cool down period and the oil in my port engine is up over a quart and I suspect I have a diesel contamination (the oil does not have the milky appearance I would expect with water contamination).
The engine is a Lees Marine Ford 2715E (Lehman with different marinization parts). I had the same problem 90 hours ago (about 4 weeks). At that time I replaced the lift pump and had no further problems until today.
I removed the valve cover and saw no signs of fuel leaks. There is no loss of engine coolant. The heat exchanger pressure checked good 4 weeks ago.
I'm back to the lift pump that was replaced 4 weeks ago. That pump had been in my spares locker for 5 years. Is it possible that the diaphragm failed from being storage? Any other suggestions on what to look for to troubleshoot? I'm out of ideas, is there anything else I should be looking at?
