What to know about the Timing Cover
The timing cover is an important part planned to guard the timing belt, timing chain or cam belt of your car from road debris, grime and gravel. The timing belt or chain of your car controls the rotation of the camshafts and crankshaft in the internal combustion engine. As long as they are spinning, the engine’s valves open and close in synchronized movement with each cylinder’s intake and exhaust strokes.
With regards on the make of your car, it will have a timing belt, timing chain or cam belt. If your car has a timing belt, the timing cover protects it from road debris that can damage and break its teeth. Without the protection of the timing cover, the belt can skip, slip off the timing gears or even break. In case of engines that include a timing belt the timing cover only guards the timing belt and can be made of plastic, metal or both.
In case of cars that have a timing chain, the timing cover secures the front section of the engine block with the help of a timing cover gasket. Thus, the timing gears and chain receive lubrication with the engine oil. If the timing cover gasket breaks, you will notice engine oil leaking. If your car has a timing chain, it will most likely have a metal timing cover.
Facts to Note:
If the timing belt slips off the pulleys, your engine will be severely spoiled.
Most timing belt covers have timing cover gaskets, which help to guard the belt.
How to Fix:
The vehicle hood is raised and held
The faulty timing cover is detached and gasket surfaces are cleaned on engine
The new timing cover is fixed and tightened to specifications
The timing is tested and adjusted as needed and checked for any oil leaks
The vehicle hood is closed and road tested for good operation
If the timing belt or chain needs to be changed, have your expert mechanics check the timing cover for damage and change it if required. Remember that oil leaks can damage the timing cover gasket, in which case the gasket can no longer protect the timing belt. If that happens, you need to change the oil seals, timing belt and gasket together.

Common symptoms indicating you may need to change the Timing Cover:
Engine oil and/or coolant leaking
A rasping or grating sound coming from the front of the engine
Missed timing marks (The crankshafts, and camshafts of the car should be perfectly aligned or timed with the moving pistons of the engine. If there is any misalignment, you will notice a sharp decrease in power when moving up inclines.)
Importance of this service:
As part of the regular upkeep schedule, make sure the timing cover is intact and working appropriately. Debris and grime can not only damage the timing belt of the car, but also damage the engine. Running the car with a damaged timing cover may lead to the timing belt slipping off resulting in severe engine damage.
