yeah I would say definitely, as the heads are sitting horisontally on the boxer engine (i.e. out towards the wheels, if you see what i mean).

Edit: then again, i've never done it, but that's my guess

are they comon to go on imprezas ??

my rads just split so im assuming its down to the headgasket presurising the system

i guessed it would have to come out due to the location of the heads

Do a compression test and see if one or more cylinders are down before you go and take the engine out, might be something else. Compression tester is only about £20 to buy and you could do it yourself.

i got a comp tester already, just when i had a cossie when ever a rad burst or bowed it was down to the h/g presurising hence me assuming the worst

besides it feels like a flat spot just off boost and a little slower to the norm

head gaskets will probably be fine depending on how long it was driven with a split radiator. The radiators are also prone to splitting due to the plastic end tanks getting brittle with age (constant heat cycling of them) I went through 2 on my classic.

Head gaskets go but I wouldnt say its a common fault, radiators however.....

Engine out job!
It makes sense to do both head gaskets while its out,just to make sure.
I had a similar problem on mine.At first it just lost a little bit of water over a few weeks then it eventually split my rad.I had the motor removed and got it pressure tested.It turned out to be cracked heads on both banks so it was a new motor for me !
