Start it up it starts shaking

I bought this car recently, there was no problem now all of the sudden when I start it up it starts shaking when driving or when giving gas. I have change oil, then change cable, spark plugs. Fist it started working fine, but after 15 to 20 miles driving it has the same problem.

Then I talk to a mechanic and he suggested that it might need head gasket valve seal cover changed. Because we found the first plug on the left with some oil in it. In that cylinder we had no oil when we first change the plug after driving a little bit oil comes in that cylinder and also from muffler there is white smoke. So can you tell me what could it be?

Thanks

I am going to take what you offer for description and run with it. I would like to start with the white smoke. First of all, the white stuff coming out the tailpipe is water vapor. That points to a head gasket. In order to get to the head you must take off the valve cover(s). You have a seal or two going out on the plug wells. That is the way I see the issue as per your comments.

I would like to add that the shaking is probably the vehicle not running correctly. I would venture that one of the plugs is cracked or a plug wire is bad. Also given the water vapor coming from the exhaust, one of the plugs or more is also tasked to boil water and therefore is not able to fully take care of the job of igniting gas. Further, let me add that there is possibly another issue here. What caused the engine to overheat and take out the head gasket? You should be looking in to that as well. I suspect a leak in the cooling system is present and responsible for this.
