Any thoughts on the oil leak?

Thanks.
Maybe you need to refix the speedometer cable mounting, it seems the cable is not correctly mounted. Renewal of the speedo cable might be the best option if the problem comes back.
For the oil leak, best to do is wash & dry the engine especially the crankshaft rear seal area. use the the car for several days then reinspect the seal area, if it is not dry anymore then the problem is in the oil seal. Normally with prolong use, the old shaft seal developed a shallow groove around the crankshaft. If the mechanic installed the new seal on the exact position where the old seal was before then the lips of the new seall is not sealing tight because it rides in the groove thus leaking the oil. HTH
