What happens if a piston hits a valve?
Cam lift and timing can put the valves dangerously close to the piston. In this automotive version of Clash of the Titans, the valves will almost always lose. If they hit the piston, you’ll be lucky to get off with just a bent valve stem.
Does the piston hit the spark plug?
If you threw a rod the piston could move up and hit the plug but it would be very loud and probably punch out the block. The wrong spark plug could be your culprit. However if you pt new plug in and it still does not fire you’ve got bigger problems. Detonation is possible and will cause your spark plug to look damaged.
What causes dropped valve?
Many things can cause a valve to drop out. Running the engine too fast (doubtful), backfire (again doubtful), misadjusted valves, weak valve, rotator or keeper. Broken valve spring.
What happens if you snap your timing belt?
Timing belts don’t often snap, but when they do, it can cause piston damage, ruined cylinder heads, and engine valve damage. Probably, when you think of your engine, you picture the valves and pistons, but you don’t think much about what keeps them in good working order. Let’s state it plainly – nothing is more important than the timing belt.
Can a broken timing belt cause bent valves?
Interference vs. non-interference engines. The level of damage caused by a broken timing belt can depend on the type of engine you have in your car. A non-interference engine provides clearance between the valves and pistons, so if the timing belt breaks, you might end up with bent valves, and you might have to have your cylinder heads rebuilt,…
Why does my Pistons squeak when my timing belt snaps?
Your timing belt tells the pistons when to rise and fall, and the valves when to open and close. Timing belts don’t often give you a lot of warning when they’re about to give way – they might squeak or chirp, or they might just suddenly break. More often, though, damage is due to wear in the timing belt.
Which is more important the camshaft or the timing belt?
Let’s state it plainly – nothing is more important than the timing belt. It drives the camshaft, which is what keeps the valves synchronized, and the crankshaft, which controls the pistons. Your timing belt tells the pistons when to rise and fall, and the valves when to open and close.
