:frown: That sucks man. I have this problem with one of my cars (old cars..) and experienced these symptons, and although I keep being hopeful, all signs point to the headgasket.
It takes a long time for you to see the effects in the oil.
Spark Plugs may have some green on them and show some wear and tear but it's not untill it gets really bad that you'll see nice oil in your coolant.
If you want to be sure, one way you can do it is:
*Drain the coolant, put in brand new coolant
*Take out the thermostat and drive the car without it.
If it's the headgasket, you'll find that the coolant level decreases and/or you it will start overheating once the water portion of the coolant is boild and/or leaking into the combustion chamber. It could take a few days, it could take a week. The sooner it happens, the worse it is. THe other thing you can do is turn the car on, have someone press the gas, stay behind the exhaust and the more water you see/feel coming out, the bigger the problem is.
WHEN it happens again, STOP the car RIGHT THEN AND THERE; I don't care where you are unless you're absolutely going to cause an accidnet, stop the car. I usually put it back in the first position since the fan and the coolant (I think..) will still be flowing. Turn your heat to max to get some of the heat out of the engine as well.
As for the car, it sounds like you got a bad car, buddy

I bought my car with problems (not the NSX) with "problems" and have spent nothing but money on it... I keep thinking "what if I do this and it works rock solid.."
