Q: Smoke from coolant filler

asked by on March 11, 2018

I have a 1991 Jaguar recently brought it. I was promised that nothing is wrong with the engine or transmission. Well my coolant filler keeps smoking and it pushes the coolant up and down. When engine is on my engine jumps. I don’t know if this is normal or i have a blown head gasket. What to do? What is wrong?

My car has 124000 miles.
My car's transmission is unknown to me.
