Genny UH-OH!

Thanks
So it looks like the plug is leaking?
The genny was serviced before the last 3500 mile trip.
And the mh has been parked for a year, this the first sign of any problem.

No, Sir. The little plate is access TO the plug. Plug requires some kind of bit/socket (forget just which) and has a gasket. Plug itself screws into the oil sump of the motor portion of the generator. It traces back to the oil filler where the yellow filler cap is.

See if the drain plug is tight.
Can you see one in the picture. i suspect that oval plate IS the drain plug!
i assume (hope?) there is a gasket behind it.
thanks guys

Take off the cover plate on the bottom. You'll need a special torx socket to get the cover plate off. I suggest you replace the 2 cover plate screws with cap screws and dump the torx machine screws. See if the drain plug is tight. Check the oil level and make sure the O-ring is on the dipstick. Onan 4K gennys are known to mark their spot if overfull or the dipstick is loose. There are several gaskets on the head and elsewhere that can leak. Spray some brake clean on the engine and inside the genny cover to see if you can find where the oil is coming from. Not to worry just yet.

The oval thing with the screw each end was a cover for the oil drain plug on my Winnebago... Onan genny. Maybe oil drain plug loosened up? Is oil now empty or is it by some chance overfilled?

On my truck, the dealer put oil in twice (??) and way overfilled it and it
started leaking out from that cover with the screws in it. That is how I found out it was overfilled. I checked the dipstick and wow... back to dealer.
