Cylinders number one, two, five and six tested 150 three was 125 and four was zero. I added a little oil in there and it was still zero. Blew compressed air n the number four it was exiting somewhere in a hurry but I could not tell where except I know some was exiting from the very top right behind the alternator. I guess it is some sort of vacuum line and some was definitely exiting through there. I want to rip the head off an get it over but want someone to tell me that is a must. I do not claim to be super mechanic but I can follow directions and get the job done. I have put two engines in and three head gasket jobs. I would think zero compression means to me it is a must. I have never done a blow down test or leak down whatever you called it, guess I could look it up. Thanks for answering I appreciate it.
