The camshaft seal prevents oil from leaking at the point where the camshaft exits the cylinder head. A leaking camshaft seal can contaminate the timing belt, cause oil loss, and produce a burning smell. It is an inexpensive part that should be replaced whenever the timing belt or chain cover is removed.
Camshaft seal leaks are common on higher-mileage engines. The seal is a simple lip seal that hardens and shrinks with age and heat cycling.
Camshaft seal replacement is often done as a preventive measure during timing belt service, adding minimal cost and time.
