Ok I took off the head and all the valves seem to be fine. I looked at the bottom and everything seemed ok. What do you think? When I installed the B20VTEC motor into my tegra it seemed to fire up just fine then the next day you can see that the Cylinder next to the Distro was not firing. YOu can see gas coming out the muffler and also if reved past 4k you can hear like a rock or something of that mature shacking around. But there is nothing in the motor. Please help!!!!!
