Is there a way to determine, without a doubt, if I have a bad head gasket or a cracked head on my civic? Will a cylinder pressure test determine that? Thanks.

if you have an bad gasket or a cracked head just save yourself the time and just change what needs to be change dont pressure test determine. its more work to be done so just call it a day

 

look under your oil cap after driving it for a while. if there's a white milky paste thing on the underside its probably a head gasket.

 

Yes. There is a tool called a combustion leak tester that uses a special blue dye that can detect the presence of exhaust gases in the cooling system. The dye will turn green or yellow if exhaust gases are present, indicating a head gasket failure or a cracked head or sleeve.

 

Did my post get deleted? Any ways does your car smoke/ burn coolant or oil? These can be indicators of a blown head gasket? And there is a ph tester that can test your coolant to tell if you have blown a head gasket.
