learned a lesson
When I got home I looked and started to think gasket between manifold and exhaust pipe. Today bought the part 2.00 then called my buddy he came over we put car on jack stands and took down ex pipe. We removed the donut and there was a small crack in it but not all the way through. Tightened everything up sarted car and noise was still there. Put my hand down to feel for leak and there it was one of the plugs for smog pump in exaust manifold fell out, so what should of taken 10 min lasted for 2hrs So lesson learned look for easiest solution then work my way up
