New Engine is a Bad Engine

I was having smoke coming from my car, so I took it to Kang Union 76 gas staion and garage at the corner of La Brea and Arba Vitae in Ingelwood California. The mechanic told me I had blown a head gasket and that he could help me. He had my car for twelve days and charged me $1300 for a rebuilt engine. When I picked up the car I was still having problems and it was leaking oil. I went back to him on several occasions only to be told, there was no problem. Every time I drive it, it smells like something is burning. One of the times I took it back to him he kept it for another day and charged me another $65. Recently, I took it to the Honda dealer for a diagnostic check to tell me what was going on with the engine, to find out why it was smoking and leaking oil.The Honda dealer said it was leaking oil in four different places and would cost me $703 dollars to repair. They also said that if I had indeed had an engine put it, I should go back to the place that did the work because with a new engine, I shouldn't be having those problems. When I picked the car up and took it back to Union 76 he said he would fix it with no problem. The last time I took it to him, he kept it for the weekend and replaced the head gasket. It is still leaking oil and smelling like it is burning. Rip Off Revenge, Please Help Me Get My Money Back!
