a boat in our club has a a yanmar GM10 and during the winter we had to put some oil down the air intake to start it , but it was easy enough , from the first bit of a problem it sometimes would start without the oil and sometimes it needed it .on launching it needed oil but then ran fine for over an hour. however the owner went out yesterday and i went with him to check it would start ok ,but no chance even putting oil down ,no luck so i put my hand close to the air intake ,Filter removed and turned the engine over only to get the palm of my hand covered in oil again and again . I can turn the engine over by hand just by turning the alternator ,so there dosnt seem to be any compression. the engine had been unused for over a year ,i can only think a sticky valve BUT? anyone had such a fault and can maybe offer some help it would be most appreciated. the owner is a newbie to sailing and i told him that this forum was the best aid to all sailing problems. Thanks for reading this. Kieron
