The engine trembles

I think that the joints were also burned because every time I turn on it, it takes water vapor when it heats blue smoke and spills a lot of oil from the front of the admission multiple but I have not checked the compression could it be a valve?

Apart the first times that began to drive it reached 180 km/Hy now no longer exceeds 140km/h also reaching 100km/h begins to vibrate the bodywork too much

If it is the normal Mustang, Deverias review the tuning, in addition to the distributor, the against exploits for the exhaust is due to bad setting, it can measure comprehensive, but it is difficult for it to be a valve, measure it hot and cold in case there is dilation and poor settlement of the valve that some see me.
