The oil filler tube on my Onan BF-MS is loose in the oil base. Not real loose, just loose enough to turn. This caused oil to blow into the air-cleaner through the breather tube. Removed the filler tube and plugged the hole, no more oil in the air-cleaner! I can't find a replacement anywhere. Has anyone fixed one of these? I am thinking of trying to expand it somehow, or even some JB Weld. Am looking for idea's. Thanks.

I expanded one of mine, but having trouble remembering just how I did it. I'm pretty sure I just took a long punch, stuck it in about 2", then rolled it with pressure to the outside. This just expands the outer end, but mine never came loose. I also did use red Loctite. I had to use a wooden block to protect the tube & a hammer to drive it in.
