Known Problems

Rear engine oil leaks may occur because Subaru used a plastic oil baffle plate that failed. This issue is often misdiagnosed as a crankshaft rear oil seal leak or an oil pan gasket leak. Subaru released an updated design of the baffle plate made from aluminum that stops the oil leak.

The head gasket has a high failure rate due to cooling system problems. Subaru is aware of the problem and has extended the warranty to 8 years/100k miles on many vehicles.

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.
