I have just finished rebuilding my dtr125 engine over the weekend after having the bore sent of for a rebore, I changed the left side crank case as I had a split just near the gear selector all went back together okay. but now I'm having oil seeping out of the joint where the to sides come tougher right at the very bottom. I have checked all screws they are tight anyone had this issue before or can suggest what the issue is thanks.

@Darty no mate just put it back together I'm going to try some JBWELD on the seem and see if that does the job. I changed the left side crank case because my gear selector had bent and cracked the casing resulting in oil leaking out the case but now the oil is coming from the seem where the 2 cases join can't win haha

You should definitely have used some sealant on the mating surfaces.. You'll be lucky if that stuff stops the leak but I would split them again and add in the sealant just to be safe. You've done the majority of the job so it's worth going back to finish it. You don't want to find another oil seep later on when it's all back in the bike

@Ads123 Sounds like a bit hit to get that damage, are the engine mounts straight?!

@Mightyman Small, cracks or surface gaps that won't flex. it works pretty well. But absolutely not the long term fix solution.
