yes they could but it depends on the position of the cam. the valves could be stuck in an open postion and then the piston comes up and could strike the valve. this is a bad scenario and i hope it doesnt happen to you
The Simple answer is yes the piston its the valves and possibly damage the pistons
Unfortunately, the results are unpredictable. When a piston kisses a valve, the valve MAY do more than just bend; it can break, fall into the cylinder and get pinched between the head and piston on the next cycle, breaking the piston and/or head. When/if a piston breaks it is also possible that pieces of piston can get pinched between the crankshaft and the side of the block, breaking the block. Admittedly, the above represents the extreme case, and hopefully that doesn't happen, but it's all possible. The recommended maintenance schedule for the L series Saturn timing belt is to replace it every 100,000 miles.
Yes, if the timing chain breaks a valve will hit a piston, causing significant internal damage. The good news is, the timing chain seldom breaks. The bad news is, if YOURS was one of the few that did break, the engine is toast.
The failure of the 2004 Kia 2.4 liter timing belt can cause severe damage to the piston heads and the valves. The timing belt failure can ruin the engine.
Almost always you will have bent valves and possible a busted piston. This is an interference engine.
In almost every instance yes, there will be damage to the valves and possibly the piston.
As I understand it, a freewheeling engine, such as the 2.3 liter Ford is an overhead cam engine that will not crash the valves if the timing belt breaks. A 350 Chevy uses a timing chain since the cam is in the block. If the timing chain breaks on that, you're out of luck.
Yes, this is an interference engine and if the belt breaks you will have engine damage. The belt must be changed every 105,000 miles.
In a freewheeling engine, the piston tops and the valve bottoms do not share the same mechanical space, even if the timing belt or chain breaks.
repair a timing cover on a 1992 ford Taurus
on 1991 ford taurus 3.8 how do you replace a timing cover
Answer: yes it could have bent some valves or damaged a piston with one or more of the valves( could have punched hole in piston or smashed piston so hard that it damaged a bearing)
