I have V-6 Volvo Penta 220. I pulled the drain plug out yesterday after bringing the boat out of the water and noticed a little oily substance coating the plug. The oil tank was full so I am not sure where to look, any suggestions?
No way we can look at it to find out what is leaking, Guess you will have to use the same methods of leak detecting us pro's use.
We clean everything up real clean, then start the engine and look for a leak.
