Are there any temp. fixes for a leaking head gaskit?

What is your question?

L have the oil in the cooling system, the rough running motor at times. If I keep a closr check on the coolent and refill as necessary it helps. The check engine light is either on or blinking. I can usually keep it within mormal temp. limits. I am planning to either fjx or sell the car but I must seal with my grandsons death first. Thank you.
