So my car is over heating, I believe it is the head gaskets, one is leaking externally oil or the oil pressure sensor is leaking, making it a little harder to tell on the passenger. On the driver side there is a very small amount of oil. With the car running I cam see bubbles now and then in the over flow tank and I think heavy moister in the exhaust. But how do I now which cylinder head is leaking? And can they be changed in the car or remove the engine?

I'd recommend pulling the spark plugs and see which plug looks different.

The headgaskets can be changed with the engine in the car, but it's a pain in the butt.

So far I've taken the passenger side head off, in the car and know I an working on Taking the drivers side off. I forgot to mention that this is the 2.5 DOHC engine. I am also curious about how the FAL-PRO MLS head gasket does that's the best the auto parts store can order in are they any good? Or should I order a different one off line?

Thank you josh, it's been fun so far the passenger side was not to bad the spark plugs both looked wet and inside the cylinder looks like it was damp. I am just assuming that you should probably change both had gaskets at the same time is this true?

If the other side isn't leaking it's not mandatory to change it.

Use the Subaru OEM gaskets. The Fel-Pro are known to fail again posthaste.

Always choose oem unless you're putting together a fun car then cometic is what I would use.
