Put a lid on it. Believe it or not, the very first automobiles did not have the luxury of a valve cover on their engines. Apparently, car owners back then had to constantly re-oil their engines because the valve train kept spitting engine oil out. Imagine how big and oily a mess those earlier engines made and the amount of effort their owners had to put in to keep them working. You're lucky enough that cars today are all equipped with valve covers. A valve cover not only prevents engine oil from being thrown out the valve train, but also keeps dirt, dust and moisture from messing up your car's engine. The cover provides solid protection over the valve train, keeping it from getting knocked here and there by whatever gets around the engine. Take note, however, that over-tightening its screws can crack the cover. A cracked cover will leak oil and allow dirt to enter the engine. Should your car's valve covers become cracked and defective, head to Auto Parts Deal for high-quality replacements.
