i bought my car from someone awhile back. and i can see that its had a lot of oil leaks in the past and still has oil all around. but its kinda hard to tell where its actually comming from. wheres the few usual places?
-and do you sugest using the stuff u buy from the store that says it will stop oil leaks if u pour it in...?

 

most common places, crank seals, senders, valve covers, bolt going into fuel pump push rod hole. i wouldn't put much faith in any in the can repairs.
