Compression Problem

Hi I have a Talon TSi 1991, with a 2.0 16 valve Turbo, The problem is that on piston 2 & 3 I dont have any compression, what could be the possible causes?

I am confused since some people say that its the head gasket, others a cracked head, others say that some valves are done...

can U help? I dont want to spend more than i should.

thanks

take the heead offf and look, then take it to a machine shop.

put a few drops of oil in the cylinder and turn the engine over again.. if the compression dosnt go up you have bad valves if the compression dose go up you have bad rings
