Pistons Hitting Valves at Melanie Mcelvain blog

Pistons Hitting Valves. The piston is a flat top with only small dimples at the valves, and the head is nearly flat, unlike most gas motors with a fairly large bowl that the valves sit in. Replace the piston, rings, and wrist pin. I just pulled the head on my 1991 nissan sentra 1.6l and noticed that the valves have been hitting on the top of the pistons. You will also need to replace the valve springs and inspect the valves, seats, and guides for. The timing belt keeps the movement of the pistons and the valves perfectly tuned, but if it snaps they can collide and catastrophic damage can occur. For it to not be. The leading cause of the piston hitting the valve is disruption of the valve by any means. These are the most common piston failures: If you have insufficient clearance, the pistons hit the valves, followed by the predictable parts. The first is usually catastrophic: Pistons in modern engines are built to last but sometimes things can go wrong. You can see the small area in the periphery of the intake valves where they hit the piston, the carbon buildup is rubbed off there. Also on the piston surface, there is just an ever so slight etching in these matching areas. When the valve is disrupted, it will remain constant while the piston continues to.
