Supporting evidence...
06 Box S
57k miles
I've never seen the temp gauge go above 175 since I've owned it (2k miles)
I had the emissions tested some two months ago and it passed without issue. (would a state emissions test pick up coolant?)
The coolant level looks a little low, but the idiot light hasn't come on
No dipstick, so I can't see if there's discoloration to the oil
motor is completely stock
oil was changed 3 weeks ago, no water was noticed (but the engine was hot so it would have boiled off anyway)
The oil level since has been high

So I guess my questions are...

1. is there anything *other* than a blown head gasket/ cracked head that this could be?

2. would a blown gasket throw a code? I connected a friends generic OBD reader and it didn't find any stored codes.

Thanks guys!
From your post I'm not sure you have a problem but these engines don't blow head gaskets, heads do crack & 175 seems low for engine temp. CEL is there for emissions compliance, it is only concerned with increased emissions.

I would monitor coolant level, remove oil filter housing & send off oil sample to a lab to check for coolant (sodium) in oil, & inspect sparkplugs to look for signs of coolant in cylinder. Looks like your car is due for a change anyway.
