Item : Generac XP Series Portable Generator
XP 8000 E
Serial # 9395033

My generator is approximately 5-6 years old. It has been rarely used. After moving to a new location about 4 years ago we noticed frequent power outages so the generator has been put to use more often. It has about 50.3 hours use on the hour meter. I power select circuits in my house through the use of a manual transfer switch and generator electrical panel. The last time I used the generator, it ran for about 5 hours. I noticed oil under the unit and all around the generator on the snow around the generator. I shut it down before it went out on low oil safety. I removed the fuel tank so that I could access the unit. There was oil everywhere. On top of the generator portion, on top of the motor, and all over the frame. I then thoroughly cleaned it up and started looking for something that might have loosened up perhaps from vibration, but nothing jumped out. At this point since I didn’t find anything I topped off the oil ( a little over 1 quart ) and started it up. No strange noises from the motor and it was generating power. I ran it for about 1/2 hour with no load. At this time since I didn’t find anything wrong I decided to change the oil and filter. At this point I was side tracked for a few days. When I returned to finish up I noticed oil under the generator again and that’s with no oil in the motor. I’m guessing
oil had sufficient time to leak down from wherever it’s coming from after sitting for a few days. Is there any breather or something else that I can look at perhaps under the pull start shrouding assembly? Looks complicated but I’m up for more disassembly. I’m open to any and all suggestions. Thanks in advance for your consideration. Jerry

This might be something where oil dye and a UV light would come in handy... The UV dye is added to the oil and you use the light to see where the dye first emerges from the engine. It's a pretty cool setup and works pretty good if you can't track something down easily!
