Re: M25 what is this and where does the hose go?
One more thing, if you guys are seeing a liquid oil discharge, not just the little tiny amount of aerosol vapor oil discharge, then you have an issue somewhere in your engine. There should be just a very small amount, barely visible, of smoke like vapor coming out of the tube, more than that is an indicator of positive pressure in the crankcase, which is, as I stated above, a problem. I recommend that you use the fuel and oil products for diesel engines that help them run cleaner, and I can highly recommend the Lucas oil treatment that goes in your engine oil. This stuff really does work, and it keeps the oil viscosity up where it should be at all operating temps, and does not make the oil thick like peanut butter when it is cold. This helps protect your valve guides and seals, rings, and cylinder walls, and your bottom end bearings, and all of those things are kind of necessary to have a good running long lasting engine.
These little engines will truly last longer than your boat if you take care of them, but if you do not, they will make good anchors if you melt them down.
It is good to learn from your mistakes, but much better to learn from the mistakes of others...
