Hydraulic Valve adjustment
This is a very common issue in higher-end cars in which the driver feels a rattling noise from the engine. This mostly happens in the winter season or on short trips. The noise comes because of the hydraulic valve adjusters which do not get enough oil to function smoothly. The noise is not definitely harmful to the engine but irritates the driver. The lifters are not able to get sufficient amounts of oil because of their poor design in lifters and cylinder heads. This type of problem is very common in the models before 2008. As the design for the lifters and cylinder head changed in 2008.
Oil leaks from Engine
It is somewhat similar to the Valve cover gasket deterioration with the passage of time. This is also a frequently happening criterion with the oil filter. The gasket seals the oil filter which connects with the cylinder head and engine. However, the oil leak is a serious issue but the oil filter leak is the most serious of all. This is capable of destroying your whole engine compartment if ignored. If there is enough leak in your engine, then oil sweeps down to the serpentine belt and covers it with oil. Then the belt will slip and go to the timing cover which will chew it up. After which the pieces of the belt will go into the engine and hence damage or destroy it.
