Major Damage to Pistons, Valves and Valve Seats. Better replace whole Engine.

You need to get the cylinder head off so you can inspect the damage.















At minimum,if valves are bent,you will probably need to replace the head.Cost wise that is the cheapest solution.















Then check the tops of the pistons for gouging.If you were lucky,all you have is minor impact gouges,but if they are deep/enough for you to feel with a fingertip,you will not have much in the way of options,because pistons are under stress and once they have been gouged they will ultimately fail















So,your going to have to replace it.(Engine)















But,have it checked by a mechanic who has this type experience before you just throw it away.















Good luck

The valves get bent and the engine will not run. Most times it the engine will spin over real fast not like it did before the belt broke. I take it that your Honda has stopped running lets not go to the worst thing first. Do a compression test, that will tell you if the belt broke or look in the oil fill cap if you can see the cam. There are many things that can make a engine stop running. And if it did break you don't have to listen to all the dune and glum I've just read in the answers about valve guides and pistons with notches in them, the valves will bend that is all. The piston needs to be looked at but will seldom need replacing even if you can feel the dent. You might think they are made of glass. If the pistons can withstand pressures of over four hundred pounds at ignition a little valve doesn't stand a chance.

will need to replace the whole engine which is cheaper















the money spent to rebuild the motor cost twice as much as installing a used motor in
