I have a 2nd gen b16 in my eg. On the tranny, just above the lower motor mount there is a little crack. But the car runs and drives fine. Is this a problem?

Thanks

 

crack where the front 17mm's go or else where above that on the gear casing? as long as it's not leaking shouldn't be a problem. if it's cracked where the bolts go as long as you have two others i suppose it's better than nothing.
