Volvo Penta oil leak
I have an oil leak in my Volvo Penta 2003. It leaks whether or not the engine is running but worse when it is. I now need to clean below the left side of the engine every day I use the boat. In the photos I have identified where the leak is visible. As you can see the oil drips down behind the engine suspension frame. I cannot see where the leak originates above the suspension frame. As you can see the frame has removed the paint on the engine block at that point. Would there be any way that the vibration or the grinding together has caused a crack in the engine block that has led to this leak? I see no signs of any crack or damage to the block.
I had suspected that the gasket for the timing gear casing is the problem. I did tighten some of the screws for that unit which led to the leak getting worse. This would seem to reinforce the idea that the it is the gasket. However, as mentioned, i cannot find a specific are of that seal that is leaking oil.
I would appreciate any ideas you may have.
