2. Engine won't turn over: If the timing belt has broken inside your motor, the engine will not be able to turn over or ignite. When you turn the key, you might hear the starter motor engage, but since the timing belt operates the crank and camshaft, it will not spin over. Obviously, if the car won't start, a phone call to a mechanic is usually the first step. However, if the issue is due to the timing belt being broken, it may also result in other internal engine compartment damage.
In many cases, the timing belt will break while the engine is running. Some of the typical damage done to a vehicle with a broken timing belt may include damage to cylinder head hardware (rocker arms, push rods or valves), damage to crank bearings or oil pump inside the oil pan. A professional and experienced mechanic will know to inspect all of these supporting components if the timing belt needs to be replaced.
3. Engine misfires: A worn out timing belt might also impact the engine's fire rate. The timing belt is attached to pulleys that drive the crank and camshaft as we've indicated above. However, sometimes the belt will slip on the camshaft drive and cause one cylinder to open or close earlier than it should. This might cause a misfire situation and if not replaced soon, may result in catastrophic engine damage.
4. Oil leaking from in front of the motor: It's also typical that the engine will leak motor oil from the timing belt cover. The cover is secured by a series of nuts and bolts that may come loose over a period of time. Another issue that will cause oil to leak is when the gasket that is found in between the engine block and timing cover wears out, is cracked or has been improperly installed and is pinched. Leaking oil from the timing belt cover commonly results in engine overheating as well and can prematurely wear the timing belt.
It's very difficult to discover a problem with the timing belt until it's too late and has broken. However, you should check with your vehicle’s manufacturer to determine when the replacement interval is scheduled and have the timing belt replaced by Timing Belt Manufacturers.
