More problems...Please help

[Panda]

Well it all started this morning when I started my car to go to school. The engine was idleing really rough ...I thought it was just becasue it was cold (coldest morning in a long time). After like 5-10 mins of nothing changing I gave up and took my other car to school. Just tried to start her up and im getting the same problem...Its also blowing white smoke that smells like gas out of the tail pipe

I've done some searching and so far ...Im guessing its a blown headgasket :oops: ....But doesn't the car have to heat up to blow its headgasket...When I parked it yesterday the temp gauge showed a tad over the quarter mark...and when I started it today it was REALLY COLD..

please help me....

thanks,
Dan

did it freeze at night? (below 0) if so u may have a blown block, just because there was water instead of antifreeze
