Another question. On this 98' skidoo 583, I've had a little oil leak underneath that drains out the bottom for about 3 or 4 years and took it in last year and they said they couldn't find anything and that it may be leaking out from some return/overflow under the engine and that they would have to pull it to find out for sure. They said it wouldn't hurt anything, but it will just leak. It's not a big leak, but enough where I have to put a pan underneath to not make a mess on the floor. Leaks less when it's cold. Is there soome easier way to find thisleak than pay them to pull my motor?
