I have a 1987 GL Coupe that I just picked up. It is running 'ok', some hesitation and a little surging. Did a basic tune up and oil and coolant (the shop had put in two quarts of oil too much and I drained it, some had dripped on the cat I think from the rear seal but stopped). Been driving it for about 2 weeks to work it out and yesterday I checked the coolant and it was down a quart and the reservoir was empty. I had put a can of conditioner in it after the change so I just filled it up and have taken about 4 trips around town to work and back and I'm getting a coolant smell every once in a while and just a wisp of steam from under the carb between the spare and the air cleaner. There as a tiny pool pf coolant on top of the block, maybe 1 tablespoon. It has a 1.8 OHC with 100k on it and otherwise seems ok. What should I be checking? Where might this be coming from? I've not seen this before in any of my EA-82's. Any help is appreciated.
