Head gasket?

How do you tell if you have a blown head gasket, i have around the same power, but i have coolant leaking and stuff around the front head of my 3.3 v6, any ideas?

You can change the oil and see if it is milky white. That can tell you that you are getting antifreeze in you oil. That could be a head gasket problem.

I changed it a lil while ago, didnt look to bad but i didnt look to closley at it either, bu im gonn have soome fun (demolition fun) when I get my new car, i did to much wrong when i went trail riding with it on some motocross trails and ramps, and drifting and drift busting the other day, I have some other problems with it too, so I think its time to get a new car

Well, it wasn't the head gasket, it was my intake gasket, and a frost plug that i replaced 4 months ago - thats an expansion plig though, so i may have thghtened it back up enough, i put in a bottle of liquid aluminum for now
