Crack in CD 70cc engine block Drain Nut

[ribbyun]

Dear Bikers, i was changing engine oil of my bike and while tightening the drain nut screw the threads got broken.
You can see the crack in block outside drain nut. As the drain nut is not getting tight and engine oil is leaking.
i went to mechanic and he said that he will use moose and make new threads ....
but later he refused and told me to go to khradia and he will install bush and make new threads. ....
please help and tell me what to do?...which option should i go for?.....
and can i get the new oil sump block? and replace the complete part rather than going to khradia?

It has three solutions:
i) Lethe Mechanic will fill this entire hole and will make thread again - some type of welding is involved.
ii) The crank case (Nut Part Only) will be changed and this part is available easily at least for CD 70. But entire engine needs disassembly.
iii) Mechanic will put some magic epoxy steel on it and will be good.

Choose wisely, my recommendation will be Option-II.

Thanks for the reply. i am also inclined towards this option. i discussed with a mechanic(Not Sure about his expertise) to replace the crank case (NUT PART ONLY) but he was of the view that complete engine has to be stripped and might be there are chances that some other problem may develop while assembling.

I think he was not that expert and was reluctant to strip the complete engine. However the other two options described by you are risky too and will involve alteration which is never advisable and problem may further aggravate.

So, i think stripping of engine by some expert mechanic and replacing the complete part would be a wise option. Your opinion please!!!!

If oil is not leaking alot i suggest to usr magic as its v hard or 20 rupay m kam hojaega.

If oil is not dropping too much, leave it and use magic as stated by @pwuser148978599914 and wait for some other problem, then fix it. However, if you are too touch like me then Option II is only solution. It is possible that on stripping entire engine some other problems may arise. But be ready for an unforeseen expenses .

Welding is not risky option, it will be done on oil change. Lethe mechanic will weld and make thread with an over sized nut. But it looks ugly in my opinion ..
