 Non turbo 4 cylinder applications all have head gasket issues, you've heard this before, most of you know this, and yes its a result of a bad/faulty design with the gasket. The factory gaskets have a coating that deteriorates over time (typically between 80-120k miles. That range is dependent on if you've run the SOA mandatory coolant conditioner, which is designed to get you past that 100k mile hump). The symptom of leaking "head gaskets" is oil weeping between the head/block surfaces. This weep over time turns into a significant leak, which then turns into coolant leaking as well, after that symptom you often times will go into overheating, from there its a few mile slippery slope...which then has coolant and oil intermingling together. If you haven't guessed it yet, this is where bearings get trashed, you develop a rod knock and hopefully at this point you've realized its about to be over but recognize before the next critical stage. The sad thing is....it doesn't need to get to this point. If you work with a specialty shop its easy to point out early on when this is happening (at the weeping stage) and proactively fixing it. By doing so, you 1- secure your investment with your vehicle, 2- save yourself the headache of being broken down on the side of the road, and 3- you get to enjoy your car for another X amount of miles b/c you didn't let it catastrophically fail. Did you know when we do head gasket jobs here at LIC Motorsports we don't install the same gaskets that do the same thing? Would you be shocked to know that the dealer and most other independents still install these bad/faulty gaskets to this day when they perform this job (reason being is Subaru hasn't revised the gasket on the older SOHC vehicles). These vehicles all have cylinder head gasket related issues:
You can purchase revised/upgraded gaskets here: Non Turbo Upgraded MLS Head Gaskets More info about our Head Gasket Service here: Maintenance Service Page Here is images of when someone has let it go to far and more or less driven there car into the "ground" (that slurry leaking out is the "milkshake" of coolant/oil that has mixed).

Just bought 2009 Subaru Outback Special 2.5i with 98k miles for $9,900 in perfect condition. Only thing wrong slight leak from oil pan gasket and will have mechanic repair for $240. Last year previous owner at 83k miles replaced power steering pump, timing belt, water pump, spark plugs, valve cover gaskets, head gaskets at Subaru Dealer. They installed gaskets part#11044AA633 single layered. I found from reading the old blog it is better to use the MLS or FelPro, etc but previous owner didn't request either. Question: How long do I have before the heads leak again? Was the original 83k a good estimate to hope for?

Really just depends on how they did the repair work. If they resurfaced the heads and did the job properly (which they don't all do), it'll last that 80-100k ish. If they didn't resurface the cylinder heads and just slapped it together (which is common for dealers to do), you'll be lucky to get 30k out of it.

Thanks for your quick reply! Would they list resurfacing the heads on the Dealer repair/work order (it's not listed on what they gave me)? Or do I have to call and quiz them on their procedure? Thanks Again!

NewOwner- yes it would be listed on your repair order/invoice if it was done.

That year/make/model does not have the issues mentioned in this post. Subaru revised the gaskets in 2010 for the outback and legacy's. Although with that being said, we do still see a lot of HG issues on your model car, reason being is the cars tend to run hot, which warp the heads, which leads to HG repair as well....but its not due to a faulty gasket like the older models mentioned in this post.

I believe only the 2.5l engines had this issue. The 2.2l is generally fine. Mine has 270k on it and is only now barely starting to weep oil I think, but not enough to register on the dipstick

correct, as mentioned in this article, its for the SOHC 2.5L vehicles. The 2.2L is the best motor Subaru made and commonly get 300k+ miles. It's a shame they stopped producing these almost 20 years ago. Your comment will be posted after it is approved.
