Ok,I made a thread about a very bad vibe with my 91 Mustang 5.0..Its either a spun bearing or somthing went south in the lower end..Changed ALOT of parts (trans,clutch,flywheel ect...) and nothings changed..Feels like the engine is going to come apart after 3500RPM and its trashed two rear seals,new one almost lasted a day...Im buying a used short block tomorrow and looking it over before buying it..Guy said its in very good shape and still has the cross hatches on the cyl walls..Ive always had cranks turned when the bearings went bad but heres my question...Once I take the caps off and if the bearings are in good shape (not burnt/copper color showing and is crank smooth),can I polish it then put it back together with new bearings??I know people have done this as long as the crank is fine so thought I would ask first...Thanks in adv...
