Cummins 6BTA5,9M1 turbo oil leakage.

[Kåre Flataukan]

This engine has nasty leak of oil from the turbo, and I suspect that the oil drain from the turbo is to blame. The drain line is entering the oil pan quite long forward on the engine. The engines fundament is sloping up a few degrees forward compared to the waterline when the boat is laying still. When the boat is doing the marching speed this inclinination is even bigger. I suspect that the inclination is resulting in too little fall from the turbo drain point to the connection point on the oil pan.

My question is therefore: Is it possible to find a point further aft to connect the drain line to the oil pan?

Pardon my english.

Broken exhaust valve and replaced turbo are classic symptoms of raw water ingestion through the exhaust.

I bought this engine 6 years ago and this leak was from the start. The engine was rebuilt with new turbo etc. I am sorry, I am not able to send you pictures as the engine is removed from the boat and it is taken apart. I had an accident: An  exhaust valve broke and ruined the cylinder head and also one piston so I will start to rebuild it as soon as I receive the parts.

I suspect your oily turbo problem has to do with your CCV system, the amount of oil in your crankcase, engine room ventilation and such.  Is this a new development?  Post pictures of what you are dealing with.
