I have a '91 s10 blazer and last week on the way home I noticed the truck smoking very badly so I pulled over and all the oil was pouring out the back side of the motor right between the tranny and the oil pan. What I need your opinion is what do you think it is, is it a rear seal or is it the cam shaft plug? or how would I check before I pull the tranny or the motor? Any help would be greatly appreciated.
