What is your question?
Shop recently replaced my plugs, had to take intake manifold off to do so; Since then, car has been running worse and worse; Check engine indicates misfire in cyl 1, took cover off intake, could see coolant on top of Cyl 1 without doing anything further, shop insists its a head gasket, would not do a compression test, told me they "don't do that", coolant pressure drops, but very very slowly, no oil in coolant, no coolant in oil, no smoke, smells or otherwise; Tried to sell me a new coil too, the cyl 1 coil is soaked, asked if they don't know where the leak is, is that smart? I think not, unless I'm eager to buy more than one coil. You can see why I'm leary.. Also, The guy at the dealership, (I'm getting it's 2nd opinion there tomorrow) says it's very likely a manifold gasket. This is based on what I'm telling you.. 1) What do you think the chances of it being a head gasket? 2) Do you believe that the shop is being honest? 3) Is there something I'm missing here? **The only other thing, the shop says that it's a head gasket, primarily because the coolant was found on top of and under the plug, and/or because he says he can see it coming in when he tries it with the plug removed. I did not witness this; **The guy also was telling me that it should be fine to drive, that I couldn't make the engine worse damaged than it is, only that it would perform worse.. This is the another red flag, you don't need to tell me thats not correct, I know better. ;) Opinions, in lieu of hard facts, if possible, are welcome;

Suspect leak at intake manifold letting coolant pond at # 1 cylinder... That will also cause misfire on that cyl.... If head gasket were leaking coolant it would be INSIDE the cylinder and would be steaming from exhaust!.. I've never heard of an auto repair shop that don't or can't do a compression test..however I guess anythings possible.
Shop tells me that the coolant is under and over spark plug, so, its in the cyl, if he isn't making it up. As I said I did not personally witness this, however. So, def on top of the plug, def visible when I just look at the top of cyl #1, with the coil in.. If mechanic is being honest, then in the cylinder too... Does that help? Also said that he could tell it was coming back in after he cleaned it all out.. I cannot verify this; but he has to take the manifold off to get that far, I'm sure of that... Exhaust is cool, nothing odd, nor any weird smells..
Hard to say without looking at it myself.. Sorry.
