What can happen between the valves and pistons if the timing belt or chain gears break?
What can happen between the valves and pistons if the timing belt or chain gears break?
However, if the timing chain breaks, the piston and valve will collide. The result will be a damaged cylinder head, valve, piston, cylinder, and/or camshaft. These are very expensive items to repair or replace. You’d probably be better off either purchasing a new engine or trading in your car for a new one.
Why is the master cylinder not resting against the snap ring?
You will notice that the master cylinder piston is not resting against the snap ring, figure 3. Occasionally connecting a pressure bleeder and opening wheel bleeder screws will cause the piston to return. You can also tap lightly on the housing, with the bleeders open, to free the piston.
Why do you need to close valves few degrees before TDC?
Note – The opening and closing of valves few degrees before TDC and BDC is required for normal working of the engine as this degree gaps provides proper completion of the operation of strokes and prevents the engine from defects like knocking, and also causes less emission.
What happens when the exhaust valve closes after BDC?
During the movement of piston from BDC to TDC exhaust valve closes 35-60 degree after BDC which seizes the combustion chamber and pressure inside the combustion chamber increases due to the start of compression stroke.and the cycle starts again.
What causes the Pistons to stick on a master cylinder?
When a master cylinder is assembled, the seals and cylinder bore are lubricated for a positive seal. This combined with air trapped in the system can cause a vacuum lock in the cylinder, causing the pistons to stick.

How long can a broken timing belt last?
Some belts are good for up to 100,000 miles. If you’re in doubt, check your owner’s manual, or ask your dealer or mechanic. The level of damage caused by a broken timing belt can depend on the type of engine you have in your car.
