Jock itch (tinea cruris) is a fungus, the same one that causes athlete's foot and scalp ringworm. The groin area is the perfect place for the fungi to grow and cause a fungal infection because it is moist, warm and dark.
The camshaft lift is the resultant net rise of the valve from its seat. The farther the valve rises from its seat the more airflow can be provided, which is generally more beneficial. Greater lift has some limitations.
Camshaft Location: The camshaft in generally located in the cylinders head or engine block. Car engines which have the camshaft located in the cylinders head are called overhead cam (OHC) engine. There are two types of overhead cams engines they are Dual overhead cam and Single overhead cam. A dual overhead cam (DOHC) engine uses two camshafts, one for the intake valves and the other for the exhaust valves.
