Default 2004 RS Headgasket

I just finished installing an OEM oil cooler and I noticed that there was some moisture where the head meets the engine block (passenger side).

When I replaced my coolant I made sure I poured in the "Subaru Coolant Conditioner" in to the radiator. I thought the moisture would go away after driving around a bit but it is still moist in that area. It doesn't seem to be a big leak but it is always wet to the touch. The wet spot looks a little black (I'm guessing that it is the headgasket's material bleeding out).

I know this is a common problem with the open deck block on the EJ25 engines, but is there a need for me to worry? Should I take the car in to the dealer and ask for them to replace one of the head gaskets? (my car has almost 20,000 miles on it) I don't mind the small leak as long as it doesn't lead to complete headgasket failure.

Thanks for reading...

Jay

If you have the 'common leaky headgasket' it would be internal to the engine, and you would have other issues.
This is a fairly uncommon issue in the phase 2 engines unless it has been overheated.

....and what is this 'oem oil cooler' that you installed and why???

Some Phase 2 engines experience HG weepage. The "conditioner" usually fixes this but it is not a pour it in and the weeping is gone. It takes many hot cold cycles for the conditioner to work because it depends on the conditioner getting through the leak area. This may take many hundreds of miles and many weeks. Just keep an eye on it at each oil change and if it continues contact your dealer. This seems to be a common problem with many makes and some manufactures are puting in the conditioner in at the factory. Ed

Uncle Scotty:

The OEM oil cooler is the one that is found on the WRX's and the Automatic Forester Models. The main reason I put it on my car is because sometimes I have to make short trips when it is very cold outside (I live in NY). This helps heat up the oil to operating temperatures a bit faster. It also helps cool the oil when I am sitting in NYC traffic.


Ed:

From what I understand, the coolant additive was already installed at the factory on the 2004 models. I just added it again because I flushed my coolant and the service manual also states that it must be added everytime the coolant is drained. I made an appointment with my local dealer just to keep it on record.

Thanks for your help

Jay
