Generator Oil leak

mojo racing · 12-12-2005, 07:48 AM

I have a Generac 4000 quitepac generator in our motorhome and when I open the cover there is oil that has leaked and or sprayed everywhere. It is not coming from the filter. Where is the leak most likely coming from as it is hard to tell because of the oil sprayed everywhere?

How many hours are on the generator? Have you checked the oil level? Could it have been overfilled? You could put on a degreaser and then hose it off then retry to locate source of leak. Let us know.

Mojo,I just went through an oil leak problem with an Onan generator. I took it to three different Onan service centers before it was repaired correct. The last place found where there was a gasket folded upon assembly at the factory. I called Onan factory and they checked with the people that repaired it last. They agreed to reimburse me on the repair bill even though it was out of warranty.

My Generac 5500 leaks around the oil pan gasket. The pan bolts loosened up after 20-30 hours of operation but I couldn't figure out where the oil film was coming from for quite some time. Finally the bolts got real loose and it became obvious. I was able to tighten about 1/3 of them but the genset has to be pulled from the rig to get at the rest and that's a big job (and I'm out of warranty now). I don't lose all that much oil so I can just top it up once in awhile, but it leaves a mess on the splash pan under the genset.

we dry camp most of the time at racetracks so our8 month old generator has 800 hours on it and is still under warranty. the problem is that the place I bought the rv from is not generac certified and they have to send the motorhome out somwhere to have repairs done. Giant pain in the but and rv dealer not the most helpful. I have changed the oil and filter every 100 hours or so and in between changes the level has never dropped below the end of the dipstick but has gotten worse lately. The oil mists all over the inside of the cabinet and then attracts dirt due to the dusty conditions at the tracks. Lately it has started to pool in the bottom of the cabinet and is just a mess! I am affraid to degrease and hose off because I dont want to do damage to the actual generator part of the unit.the engine itself I think is made by briggs and stratton and the original oil filter had a flat gasket but now the filters i get from fleet farm (generac brand) have a round o-ring type gasket. I thought maybe this was the problem but it doesnt seem to be leaking from there. My thoughts were that maybe it was coming from a breather or something. Do the briggs engines have an oil pan per say?
