I have a 86 GL with the ea82 non-turbo. I found coolant sitting in the recessed area where the spark plug is on both sides of the engine. I have to put in a "little coolant every couple of weeks. the car has 160,000 miles on it and i believe it has sat for a long time not running. is this the intake manifold gasket? head gasket? will my car keep running for a while till i can get the time and money to fix whatever the problem is?

Look for bad hoses. Might also be the intake manifold gaskets, yes. When you replace them be very careful not to break the bolts getting the manifold off, use OEM gaskets from the dealer ONLY, chase the threads with a tap & die and then torque to 12 ft/lbs.
