Subaru Impreza Outback Problems
Front engine oil leaks can develop from the camshaft seal and the crankshaft front seal. If one or more seals require replacement, it may be wise to consider replacing the timing belt as well. These seals are commonly inspected and replaced as needed as part of a timing belt service.
The leak may develop from the oil pump seal. Our technicians prefer to use thread locker when replacing the seal to prevent the bolts from becoming loose again.
