Engine Oil Leaks with Subaru Engines in General

Asked by Sep 16, 2012 at 02:55 AM about the 2012 Subaru Forester

Question type: General

I'm planning on purchasing a new Subaru Forester, but I've heard that Subarus in general have problems
with the engines leaking oil after 40K to 50K  miles. Is this true? Has the problem been resolved

It's pretty typical of all Subaru's with the boxter engine. Nothing I know of has been done to fix the issue. The only way I know of to fix the issue is to run factory recommended oil (I prefer Castrol) and add Lucas Oil Stabilizer.

leaks are normally from rocker cover gaskets at the side

i have an 01 outback with 175k miles and it never had a leak problem some engines need a head gasket rebuild which mine did which could have been the reason for no leaks

I have an '08 OutBack with 98K miles. Not a leak to be found. Engine and undercarriage is clean and dry.

50,000 miles would be premature for a Subaru. My 2003 has 197,000 miles on the original gaskets but does leak some oil. Use Subaru anti- leak in the radiator, replace coolant regularly with the proper type, use a good grade gas so you don't have pinging and maintain the battery connections. These things will help extend your head gasket life but due to the open block design of Subaru engines the head gaskets will have to be replaced sooner or later.

Subies can run a "wet diaper" more as a function of TIME (and luck) rather than mileage rolled around. Minor leakage at the valve cover spark seals...and maybe even a rare rear main seal...can be reduced by using a petroleum "stop leak" oil conditioner. 2.5i right side head gasket oil leakage, however, has no cheap fix. As I mentioned elsewhere, using 10w oils instead of 5w (or especially 0w synth!) will seriously abate oiil consumption rates. Remember that boxer motors sit in fluids at rest, and are butterflied "open", so isothermality is difficult to achieve, resulting in the increased chances for running wet with age. Thicker oils work well.
