I have a 02 Honda civic ex c tech 1.7. My heater stopped working and i realized that my radiator fluid was nasty so i decided to change it out. After doing that an an oil change and cleaning everything up my thermostat wouldnt click on so my car started to over heat. I hooked it up to a compression tester and found out that i had a leak somewhere but the radiator and the hoses were all brand new. I decided that it was probably a cracked head or a messed up head gasket and i am recently trying to get the throttle body off to remove the head. The fuel rail is not coming off and i need some help. Can anyone please help me.
