whats the financial damage for me?

So basically, the oil on my 02 wr426 was being changed and the drain plug was turned the wrong way. to fix it, we tried the heelacoil, but didnt have the right screw so we were rushing. Then we tried a self tapping screw, which completely cracked offf the bottom of the crank case:crazy: whats the damage? anyone done this? what did you do

Do you mean the screw "cracked off" in the bottom of the case, or when tightening the screw, you cracked the case? Pics would be helpful...

sounds like you got in a hell of a mess. As said above you might want to post some pics to give us a better idea of what happened. I think it's beyond JB weld solution, though

yes, i cracked off the bottom putting the screw in. ill try to get some pics later today

Something similar happened to my XR250 years ago. I boogered up the oil plug threads and ended up trying a self-tapping bolt. It caused a hairline crack radiating about a half an inch from the hole. I "fixed" it with JB weld eventually and it didn't leak. But now I reread your post and it said the bottom of the crankcase cracked off. I think it's way beyond repair such that replacement is the only option. A new set of crankcases for an '02 is about $600. Expensive lesson.
