I have a 93 civic hatch. I threw in a b16 but I am running the stock computer for right now. Well I got my car to start and it turn on fine it idles up and down but I sounded fine then I took it for a test drive and on my way back hone it started smoking real bad its like a witheish blueish smoke and it smells like gas I already changed the map sensor and the IACV too and its still doing the same thing. O yea the engine I put on was sitting for like around 1yr and a hlaf. One mre thing my car only starts with starter fluid. HELP Me

Remove all plugs and check each cylinder's compression. The results will likely show the head gasket blew, due to head warpage (overheating). The engine is now burning coolant and oil, which are leaking into the cylinders. You will likely have to machine the head and examine the valves for damage.
