I have a 2006 Winnebago Vectra with a Onan 7500 Diesel Generator. When I purchased it from the dealer he acknowledged a problem with oil leaking from the oil pan but promised to provide me with a new one and pay for the labor to have it done. Within a few weeks the new oil pan arrived but when I gave it to the repair shop they noticed right away that the pan had major cracks in it - identical to the ones in the old pan - that went right to the drain plug opening. The new plan leaked - when we tested it. Whoever makes the oil pan for Kubota is manufacturing a pan with a bad cast. Is anyone else experienced a problem similar? I've ordered yet another oil pan but I'm becoming every frustrated.
