I have a 1994 Toyota Corrolla. It has a 4AFE 16valve engine. I just recieved the car as a gift and it has an issue. The number 1 cylinder registers 0 compression. The other 3 cylinders register 180-190. I put a little oil in each cylinder and retested. Still 0 compression on the # 1. I pulled the valve cover to check the alignment of the cam pulley with the bearing mark with #1 @ TDC. I then proceded to the crank pulley to check that with the cam in position the notch on the crank pulley would be aligned with -0- on the timing belt cover. I basically have a few inquiries. First, if the notch in the crank pulley was passed the -0- mark on the cover by say 1/8". Will that cause me to register 0 compression on #1 cylinder? Second, I manually pushed down each lifter to see if I could feel or hear the valves moving freely and reseating. Is that a stupid test? Third, could this be caused by a head gasket? I'm basically an intermediate mechanic. I only do this when I have to because we're poor folks with three kids any help/guidance in this matter would be greatly appreciated. Thanks J.B.
