I have a 1986 Johnson 90 hp and I have injector oil running down the leg. Its quite a bit. I have not run the engine for a couple years. I moved the boat out of the driveway to shovel snow and when I put it back I noticed the oil. Its strange that it would leak just sitting there. I wipe it off and its back again. I did check the hoses to the vro and it looks okay. How the heck can it siphon from oil tank when not in use. Any help would be greatly appreciated. Thank you

Pressure can build up in the oil tank when sitting due to a bad fill cap not vented. Check all that out.
