Well we are back from 2 weeks on the water....2 days of which had great wind!. Question for the group. on our return trip we developed 2 problems......1.. we had blue smoke coming out our exhaust..in access of usual......Our mechanic on first hearing of this is thinking ring job.......but the second problem was blackish smelly smoke coming up from our compainionway from the engine.....upon opening the compartment..there was rubber dust..I thought the belt was readjusting itself since I had just installed a new one...but as we progressed the compartment filled with black oily residue.......We thought exhaust leak......But after further discussions belive it is unburned diesel fuel that has vaporized..the cabin filled with this stuff....we shut down and had to be towed back in.....the black "oily" substance is everywhere...in all interior compartments.........We are looking into alot of senereo's the largest is engine replacement....we have already rebuilt this engine....the engine is almost 20 years old......(Perkins) ..in the course of its life the "previous owner" (whom I hold no trust in) said it sat for 10 years.engine hour meter is only 700 hours....but it runs as though it was beat to death...... So the question for the group..what is the oily residue in our cabin. Post note:...water temp/ oil pressure gauges and tach all read norm..dip stick before starting was fine...antifreeze good...sea strainer clear...charging systems all were ok.....just smoke....havent tried to start it since we were towed in...thanks for your help.

Yes, but...

Just a WAG..
...since I am not a mechanic. I agree with the real mechanic. Shot rings or at least stuck, would cause blue exhaust smoke. It could also cause higher crankcase pressure resulting in a mist of oil and fuel coming out the crankcase vent. Start it up and check the vent line for excessive oil/fuel.

Exhaust
I had this same stuff in the cabin from a broken water injection elbow. Its oily, sooty diesel exhaust mixed with some seawater. However, most of your questions can be answered with a thorough inspection of the engine and related systems, including, of course, the exhaust system. Get someone who really knows what to look for. jv

What did the mechanic say?
You said in another forum that you were meeting with the mechanic. What did you find out about your engine problem?
