Hello,

I got some cracking near the drain plug on my oil sump (or pan, what ever you want to call it.) I had some retard do a shitty weld job and he filled the whole thing. Now I can't change my oil at all. Sweet! What I would like to do is replace the whole pan (or sump) but I can't find one. Any one have one kicking around? It would probably take one from a 350 too....

Thanks,

Eric

hey, careful on that drain plug. you'll crack the pan. haha, couldn't resist. I've done it myself. I have a 400 pan but it's in rough shape. I'll bead blast it and see how it looks for ya.

donald, you're a sick bastard

eric, I just re-read your post. if it's completely welded shut you should have someone retap the hole. simple for someone with the right tools.

The weld job this guy did sucks. He bitched about it not being 100% aluminum and said it was some cheap alloy. As a result it looks dumb and it still has a slow drip through his welding. Since I would still have to take the pan off to get it welded again and then tapped, I'm thinking maybe I could just find a replacement pan rather than keep paying people to fuck up my bike. Should I be pissed at the Japanese or this local dipshit of a welder?

it's probably true that it is some alloy but that doesn't mean it can't be welded. he's probably never changed settings much on his welder and just has one setting for aluminum or he didn't clean it well or who knows. did he weld the plug in? aaron could surely fix it. I'll still take a look at that pan if you want.

No, the plug is not in. He just filled the hole with aluminum. It looks my bike has an outie belly button now. I'd kind of like to replace the pan if possible. But I'm open ot what ever you guys think would be best.

CB oil pans are all die cast. Die cast aluminum has silicon added to reduce the tendency to crack. But, silicon makes it harder to weld. If your welder had ever welded a die casting before, he'd know that and should have been able to compensate.

On the other hand, being a very old die casting, Honda may have used more silicon than is usual today. So, even a very experienced welder might have had trouble with it.
