I had my oil changed at Walmart and they would not do it because they said there was an oil leak and they could not tell where it was coming from.. Went to Pep Boys and they did the oil change and told me I did have a oil leak as well but to check it often.. I drove from Georgia to California and only used about 3 quarts. Yesterday, Low oil pressure light comes on.. No oil at all showing on stick... I put in 3 quarts... I start driving and while smoke is blowing out the back from oil getting on engine.. It does not blow more smoke if I hit the gas.. Anyway, to go 50 miles I had to use about 6 quarts.. Any ideas for where to start? Like I said, no signs from looking down from the top.. Of course under it is coming out from the right side... any help would be great.. Thanks glee
