No Compression in any cylinder


New Member
I recently replaced my head gasket as well as all of my piston rings and now when I go to start the car it only cranks. It does not sound like it is firing. I did a compression test on all of my cylinders and they all have zero compression. I thought a valve could be stuck open so I tuned the intake valves to 0.003 inches and the exhaust to 0.006 inches. This had no effect on the compression results. Have any of you had a similar problem? Or do any of you know what this could be?
